Description

Ecological urinal

The invention relates to an ecological urinal, particularly economic and ecological or environmental vocation, with the advantage of requiring no connection to sewers, water or electricity distribution systems, particularly easy and inexpensive maintenance , allowing the "run-of-the-river" recovery of the nitrogenous substances contained in the urine, the main substances at the origin of the nauseating olfactory nuances resulting from their natural oxidation.

This urinal has been designed to respond to the problem of cities and agglomerations subject to significant seasonal tourist influx, which especially in the summer, are not able to cope logistically and humanly with the sharp increase in the demand for sanitary facilities at affordable costs for the community. The summer influx generally coincides with higher temperatures, likely to amplify the olfactory nuisances induced by "wild urination", excluding appropriate sanitary equipment.

It is known that these urinations carried out outside the sanitary facilities, most often due to the chronic lack of so-called sanitary facilities in busy periods, represent a real problem both sanitary and environmental comfort in cities and towns with strong frequentation, in particular because of the olfactory nuisances resulting from these urination outside facilities.

On the other hand, it should be noted that to date, apart from some models of "dry toilets" whose development remains anecdotal, or so-called chemical toilets using environmentally binding products and requiring maintenance time-consuming , labor and logistics, the installation of adequate urinals that would cope with a seasonal increase in demand systematically requires heavy logistics and binding in the case of chemical toilets, and most often, a water supply for their cleaning and a connection with the sewer system for the evacuation of dirty water and urine emitted.

These temporary needs represent a considerable cost for the community related to the establishment and then the maintenance of semi-durable or even permanent installations which finally occupy a volume on public space not justified, even during periods of seasonal affluence .

The invention thus aims to overcome these disadvantages and proposes a urinal with a vocation both ecological and economic, temporary or permanent, small footprint and totally natural, low installation cost and maintenance.

According to the invention, this urinal comprises a bed of chabasite material, a bed of covering material covering said bed of chabasite material and able to disperse the urine collected by the urinal on said bed of material based on of chabasite, so as to allow at least one adsorption of the nitrogenous material of the urine by said bed of chabasite material. In the following, said bed of chabasite-based material is also designated as a bed of organo-mineral material, namely predominantly chabasite-dominated mineral material, and said bed of roofing material is also designated as a bed of predominantly organic material and vegetal cover.

This organo-mineral bed is designed to absorb water, the main component of urine with more than 95% of its constitution, but also and more importantly to adsorb in its polytetrahedral crystalline structure all the ammoniacal nitrogen derived from the degradation of nitrogenous materials in the urine, in particular and above all urea, which represents more than 2% of the urine, and which is at the origin of its degradation in ammoniacal form of the unpleasant smells characteristic of the "old urine" .

Chabasite, a natural volcanic rock, has the unique characteristic of being able to trap immediately and in unparalleled quantity in the mineral world - that is to say up to 18 g per kilogram of rock, or 18 times more than ordinary clay - the ammonia nitrogen NH4 + from the degradation of urea urines, and keep it at the very heart of its crystalline structure. Once trapped and trapped in the crystalline structure of the rock, ammonia nitrogen is no longer able to disperse by atmospheric in its gaseous form, namely NH3 ammonia, the main air carrier of olfactory nuisance.

The interest of this double water-absorbing trap and ammonia nitrogen adsorber also lies in the unique ability of the chabasite to gradually absorb the ammoniacal nitrogen stored in the structure when and only when it is solicited by humic acid plants, whose roots are in search of nitrogen for their growth, nitrogen being one of the essential nutrients of the plant world.

The ammoniacal nitrogen trapped in the crystalline structure of the rock is therefore released into the surrounding environment only during the organic growth of a plant, thereby ensuring the growth of the plant while avoiding the leaching of the medium. prior to this organic growth. Ammonia nitrogen is thus immediately trapped, then stored and made available to the plant cover precisely and only at the time of organic growth.

The system thus designed makes it possible to manage and treat naturally and without any external intervention quantities of urine in theory without limit, since able to separate "over water" urea of its water component.

Said bed of covering material may comprise a fiber network, for example of plant and / or carbon fibers, capable of constituting at its interface with the bed of chabasite-based material a microorganism substrate promoting at least said adsorption exchange by the material based on chabasite and transformation by microorganisms of ammoniacal nitrogen from urea urines.

Said bed of chabasite-based material is advantageously pure chabasite derived from volcanic rock or at least one substrate containing more than 50% of chabasite. Said material based on chabasite may be in the form of a powder, aggregates or adjoining blocks or in one piece. The thickness of the bed of chabasite material may vary, for example from 15 to 60 cm. It may extend over a variable surface, for example from 0.5 to 5 m ² , depending on the said thickness to constitute a sufficient adsorption volume of the collected urine, said material containing chabasite being able to adsorb indeed about half of its volume in water so urine.

Said bed of cover material is advantageously insulating due to bed thickness and bed density while allowing aerobic exchange between the chabasite material and the urine. Said thickness may vary, for example from about 5 to 30 cm or more.

Said bed of cover material may contain an organic and / or inorganic material, for example based on soil and potting soil, a carrier for plant organisms, especially organisms with a high consumption of nitrogen such as leguminous plants.

Said bed of covering material advantageously comprises a network of fibrous materials at its interface with the bed of material based on chabasite. It advantageously comprises a cover of organic and / or mineral material supported by said network.

In this way, said plant organisms by adsorbing the nitrates and water resorbed by the material based on chabasite participate in the automatic cleaning of the latter for the adsorption by it of new nitrogenous material collected urine.

Said urinal advantageously comprises at least one inclined plane block or bowl covered with a hydrophobic substrate, so that the residual urine traces in the block or the bowl are pushed towards the bed of covering material. This bowl is connected to at least one urine drain pipe leading to said bed of cover material for dispersing urine on the bed of chabasite material.

Advantageously, said evacuation pipe leads to said bed of covering material in a network of dispersion and distribution of urine on said bed of chabasite material, preferably at the interface with the latter.

The said urine dispersion and distribution network is configured to advantageously allow homogeneous dispersion of the urine on the chabasite material, for example by means of holes drilled along said pipe. The arrangement of the holes is provided for this purpose, for example more tightened towards the end of the pipe. If necessary, a urine delivery pump can be mounted on the urine drain hose circuit.

Said urinal advantageously comprises a sealed container for restraining said beds of cover material and chabasite-based material and a support panel of said urinal bowl. Thus, said urinal can be disposed at a convenient location for its use without being constrained by the presence of a water system for a conventional cleaning of the urinal. Said tank is heavy enough to allow the urinal to be held in position. Moreover, one of the 'faces of said panel serves to allow the user to utter the uttermost discretion, for example by using lateral baffles on either side of the bowl, while the opposite face can serve advertising support or message communication.

In addition, the presence of plants in the tray adds an aesthetic or even ecological character to the device.

Naturally, the device can be extended to the use of several people in a set comprising a sequence of adjacent urinals, such as those mentioned above, or in a set comprising a single container of said beds of cover material and material to Chabasite base and a single panel support urinal bowls.

The invention also relates to the application to the urinals of the treatment with a material containing chabasite urine collected by the latter, namely to adsorb the nitrogenous material of the urine and obtain nitrates and the water for the growth of plants.

Other features of the invention are indicated below.

Plant fibers and other carbon inputs judiciously added and finely mixed with the dominant mineral material will, thanks to the development of aerobic microorganisms, transform the salted ammoniacal nitrogen into N03- nitrate, which corresponds to the form of nitrogen absorbed by plants and any plant organism.

More specifically, said contribution of carbonaceous material intimately mixed with the chabasite, main constituent of the mineral bed whose vocation is to allow the immediate adsorption and then progressive release of the ammoniacal nitrogen may be a simple inert and non-composted plant fiber feed , for example vegetable waste or fibers, or even simple particles of activated or non-activated charcoal, capable of favoring - uniformly and throughout the bed of organo-mineral material thus formed by intimate mixing of organic carbonaceous materials and mineral matter with chabasite base - the development of microorganisms that will proliferate on this ideal support substrate, allowing the natural and rapid nitrification of the ammoniacal nitrogen released by the chabasite and thus its transformation into nitrates which will ultimately be consumed by the plant tissue covering in its second stage the predominantly Chabasite bed, but considered organo-mined ral because combining fibers, carbon input and mineral adsorber.

All of these constituents thus intimately mixed will allow the aerobic elimination of water and urea urine by the plant tissue overhanging the organo-mineral bed thus formed.

The main mineral component of said bed of predominantly chabasite organo-mineral material is preferably natural chabakite from volcanic rock with a chabasite purity of more than 60%. This high purity of the mineral input is made indispensable by the need to instantly adsorb the ammoniacal nitrogen resulting from the degradation of urea urines, to prevent any occurrence of olfactory nuisance characteristic of said degradation. This degree of purity is also indispensable because of the very high Cationic Exchange Capacity (CEC) of the chabasite, which characterizes this specific crystal structure in comparison with zeolites (Zeolith - "stone that boils") more common or other minerals not having the exceptional capacities of trapping and release of the rock specifically chosen.

The organo-mineral bed thus constituted of an organic, carbonaceous and mineral mixture will consequently have to contain at least 50% of chabasite to ensure sufficient and sufficiently rapid trapping and release, a prerequisite for good nitrification and elimination water "nitrogen derived urea urines, and this without appearance of any odor nuisance.

Said material based on chabasite may be in the form of a powder, aggregates or adjoining blocks or in one piece. The thickness of the said predominantly Chabasite organo-mineral bed may be enriched with plant fibers and other carbonaceous elements intimately mixed with the mineral bed and may vary. It may extend over a variable surface, for example from 0.5 to 5 m ² or more, this surface being stopped depending on the said thickness of the organomineral bed and the intended use in terms of daily volume of urine to be eliminated.

The overall volume of the organo-mineral absorber and adsorber bed thus formed by adjusting the two sliders height x surface must indeed have a sufficient absorption and adsorption volume of the urine collected, said material containing chabasite can absorb in effect about half of its volume in water, composing 95% of the urine, and adsorbing up to 18 kg of ammonia nitrogen per ton of mineral present, at the purity levels as previously stated.

On the upper floor of the installation, said bed of plant cover material covering the bed of organo-mineral material predominantly chabasite is advantageously insulating due to a sufficient thickness of the bed consists of soil and soil now the plant tissue surface, and a bed density thus formed avoiding any deleterious outgassing of ammonia associated with the degradation of urea, while allowing an aerobic exchange between the predominantly chabasite organo-mineral material located on the lower floor of the plant during the application of the urine collected upstream by means of a suitable urinal container, in order to allow the cation exchange and nitrification of the ammoniacal nitrogen resulting from urea under favorable aerobic conditions .

Said plant cover bed may contain a carrier material of plant organisms placed on the surface, especially nitrogen-intensive organisms such as leguminous plants.

If the absorption of water in addition to the ammonia nitrogen adsorption is made necessary because of high use and therefore use of the installation, it may be envisaged to also use strong growth, such as different species of bamboo or similar, as well as shrubs with a high combined consumption of water and nitrogen, such as willows or comparable species.

Said plant cover bed advantageously comprises a dense network of fibrous and rooting materials up to its interface with the bed of organo-mineral material based predominantly chabasite. It advantageously comprises at this interface an intense root network supported by said network, the racineal hair of the plant tissue having a vocation to develop progressively in depth through the bed of underlying organo-mineral material, in order to develop an underground right of way in relation to the surface growth, and especially to draw water and nitrogen fertilizer allowing their elimination along the water by biomass formation.

In this way, said plant organisms by absorbing the nitrates resulting from the natural nitrification of ammoniacal nitrogen from the degradation of urea urines, adsorbed and then gradually rejected by the chabasite and converted into nitrates by the microorganisms present, as well as Urine water, contribute to the automatic cyclic cleaning remanent urine previously rejected, allowing to start a new cycle of adsorption / salting / nitrification / elimination of nitrogen compounds urines, virtuous cycle allowing the continued use of the system without intervention external and no contribution of any chemical or not, thus offering low operating costs (no equivalent to this day) and in a totally natural environment. Apart from a light sanitary maintenance, the only external intervention will be to recover from time to time the surface biomass produced by the plant tissue benefiting from the abundant presence of water and nitrogen fertilizer, in order to export the same. Nitrogen supplied by urine urea and duly transformed into biomass.

Said urinal has in its receptacle portion intended to collect urine either urinal blocks of conventional materials including ceramics, or advantageously for collective use a bowl with inclined planes covered with a hydrophobic substrate, so that traces of residual urine in the bowl are repelled and quickly evacuated to the absorber bed and organo-mineral adsorber predominantly chabasite.

These blocks or bowl are connected to at least one urine drain pipe leading to said organo-mineral bed for the purpose of dispersing urine through said bed of predominantly chabasite material.

Advantageously, said urine drain pipe leads to said organo-mineral bed in a network of dispersion and distribution of urine on said predominantly chabasite material bed, preferably at the interface between the organomineral bed and the the cover supporting the plant tissue.

Said urine dispersion network is configured to advantageously allow a preferably homogeneous dispersion of the urine on the predominantly chabasite organo-mineral material, for example by means of holes drilled along said pipe. The arrangement of the holes is provided for this purpose, for example more tightened towards the end of the pipe.

The variable density of the mesh of the dispersion orifices makes it possible to compensate for the lesser presence of urine at the end of the distribution pipe.

If necessary, a urine delivery pump can be mounted on the urine drain pipe circuit to approximate the ideal urine distribution conditions over the entire surface at the interface of the organ bed. -mineral and plant cover support. In order to contain and assemble the two stages of the installation, namely the organo-mineral bed predominantly chabasite and the cover-support of the plant tissue, separated at their interface by the pierced said pipe distributor, said urinal advantageously comprises a sealed tank contention of said constituents and a support panel of said bowl or urinal block for collecting the urine of people.

Thus, said urinal can be disposed of in a location suitable for its use without being constrained by the presence of a water network for a conventional cleaning of the urinal, and therefore in the absence of heavy logistics, both installation than maintenance.

Said waterproof container contention is sufficiently heavy by its intrinsic organo-mineral content plus the plant cover to allow the proper holding in position of the panel on which is fixed said bowl or urinal block.

Furthermore, one of the faces of said panel is used to allow the user to urinate in any discretion; for example using side baffles on either side of the bowl or urinal block, while the opposite side can serve as an institutional or commercial message communication medium.

In addition, the presence of plants in the tray adds an aesthetic character, even ecological device, or even olfactory, using for example the growth of sweet peas, known for their rapid growth, thriving and consuming a lot of nitrogen .

Naturally, the device can be extended to the use of several people in a set comprising a series of adjacent urinals on the same panel, such as those mentioned above, or in a set comprising a single container of said beds of roofing material and chabasite-based material and several support panels cuvettes or urinal blocks distributed around said contention tank.

The invention also relates to the application to the urinals of the treatment with a chabasite-based material of the urine collected by the latter, namely to adsorb the nitrogenous materials of the urine and to extract nitrates and water for the growth of a plant tissue allowing their elimination "over the water".

The invention is illustrated below with the aid of an exemplary embodiment with reference to the appended drawing, in which:

FIG. 1 is a sectional view of an embodiment of a urinal according to the invention and

- Figure 2 is a top view of this urinal.

With reference to the figures of the drawing, there is illustrated a urinal 1 with a single bowl 3 for receiving urine. This urinal comprises, according to the invention, a bed 5 of organo-mineral material predominantly chabasite and a bed 7 of covering material covering said bed 5. The bed 7 forms a distributing member collected urine. This distributing member 7 is capable of dispersing the urine collected by the urinal on said bed 5 of material based on chabasite, so as to allow at least immediate adsorption of nitrogenous materials from the urine by said material based on chabasite.

It is indeed a faculty of this material based on chabasite from volcanic rock to adsorb in principal and in particular ammoniacal nitrogen derived from the degradation of urea contained in the urine and responsible in its ammonia form of Olfactory pollution associated with urine and characteristic of aerobic degradation of urea.

Thus, the bed 5 of predominantly chabasite material traps downstream and instantaneously the nitrogenous matter contained in the collected urine and thus prevents the release and aerial dispersion of ammonia gas in phase equilibrium with the ammoniacal nitrogen resulting from the decomposition of said nitrogenous materials.

This adsorption of nitrogenous materials in ammoniacal form by the material based on chabasite is followed only in a stressing situation by the plant tissue covering the organo-mineral support, a very progressive retrocession of water and NH4 + ammoniacal nitrogen. then transformed by the presence of the microorganisms present thanks to the vegetable fibers and other carbon contributions intimately mixed with the ideal substrate constituted by the chabasite. The exploded crystalline structure of the rock represents the ideal substrate-substrate for the microbial flora thus favored and abundant: this particular fragmented structure offers both a considerable developed surface allowing the fixation and proliferation of microorganisms conducive to the transformation of the materials. nitrogen but also a large volume intrinsically empty and available contributing to the insulating qualities of volcanic rock, and therefore its strong capacity for thermal and hydrous smoothing of the medium containing it.

It is indeed essential to emphasize that the fractal structure of the chabasite allows an intense inter-crystalline aeration favoring the free circulation of air and therefore of oxygen. More intrinsically, the large intracrystalline cavities are privileged places of water storage, with a water retention up to 50% of the mineral volume, but also air in cavities waiting for water and of cations. These very particular characteristics of volcanic rock allow the maintenance of a sufficient aerobic conducive to the transformation of the ammoniacal form into NO3- nitrates, henceforth able to be picked up by the hair so the root system of the plant tissue surjacent that develops in depth through the organo-mineral bed precisely available for easy collection of nutrients. Nitrogen and water thus collected are finally consumed and eliminated by the plant cover plants above the organo-mineral bed, such as those represented at 9 on the surface of the cover 7.

Said cover 7 is here constituted in its thickness of soil or soil supporting and maintaining in its surface a plant cover with rapid growth, consuming a lot of water and nitrates, in order to capture by the root system and then eliminate and as a result of organic growth, water and nitrogenous materials from the urine collected. Said bed 5 of material to. dominant chabasite is here chabasite with a very high degree of purity derived from volcanic rock, which maximizes its efficiency, but it can be a mixture of substrates containing at least 50% of pure chabasite. Said material based on chabasite may also be in the form of powder, aggregates or adjoining blocks or in one piece as here. The particle size can in particular be decreasing in depth to promote the adsorption of nitrogenous materials by the chabasite-based material and promote the drainage of the water at depth, in order to encourage the root system to develop in depth, thus maximizing the collection of nutrients made available to the plants, but also the good physical fixation of the plant tissue.

In order to allow the good aerobic transformation of the ammoniacal nitrogen gradually released by the crystalline structure of the mineral substrate, it is essential to provide the medium with a complement of non-composted inert vegetable fibers - also considered as green waste - as well as carbon inputs. mineral or organic origin. The intimate mixture of Chabasite and these inert or carbonaceous vegetable inputs is the ideal conditions for an immediate and rapid aerobic transformation of ammoniacal nitrogen into nitrates, the form available to plants for nitrogenous matter.

This vegetable intake supplemented with a carbonaceous feed will form by simple natural degradation through and in the volume of the bed of organo-mineral material predominantly Chabasite a substrate 11 supporting microorganisms promoting said virtuous cycle of adsorption and resorption between the urine collected and the material of chabasite.

The thickness of the bed of organo-mineral material predominantly chabasite is in the example of about 30 cm but it can vary, for example from 15 to 60 cm, depending on the desired adsorption and absorption capacities, as well as plants finally installed on the cover. Shrubs with high water consumption can still be installed. They require deeper rooting than legumes and other surface plants that consume nitrogen.

The bed 5 of chabasite material here extends about 0.7 m ² in a substantially square sector of a little more than 0.8 m side, but II can extend over a variable surface that can represent several m ² , a function of the said thickness of the bed to constitute a sufficient absorption and adsorption volume of the urine collected, according to the frequency of passage and the number of people to the urinal, said material containing chabasite may absorb on the water level up to about half of its volume.

Said plant cover bed 7 also plays a role of relative thermal insulation, providing buffer conditions in temperature and humidity favoring the good microbial transformation of nitrogenous materials at their different stages of transformation.

This combined thermal and water smoothing is also favored by the underlying presence of chabasite, whose cavities hold water and air to ensure ideal buffer conditions for the aerobic transformation of nitrogenous materials. The thickness of said vegetation cover is here 10 cm but may vary, for example, from about 5 to 30 cm. Said plant cover bed 7 contains an organic and / or inorganic support material 13, essentially soil or potting soil, advantageously forming a support for plants 9, especially plants with a high nitrogen consumption such as legumes or other plants. and seedlings (peas, alfalfa, bamboo, willow etc.).

Said plant cover bed 7 advantageously comprises, below its surface plant tissue, as here a network of fibrous materials, for example an intense root-derived cellulosic mesh developing progressively in depth through the underlying organo-mineral bed, the growth sought to secure the two floors of the installation starting at a pipe 19 dispatcher of urine, so at its interface with the bed 5 of predominantly chabasite material and bed 7 covered with organic support and / or mineral, such that said soil or soil 13, supported and fed by said network 15.

In this way, said plant organisms 9 by adsorbing the nitrates and the water resorbed by the material containing chabasite participate in the automatic cleaning of the latter, which maintains its adsorption capacity thus renewed new urine nitrogenous material collected , which makes it possible to treat new urine and this in the framework of a permanent and permanent virtuous cycle thus put in place.

Said urinal 1 comprises either conventional urinal blocks, for example ceramic, or advantageously a bowl 3 with inclined planes 17, as shown, covered with a hydrophobic substrate (stainless steel coated with hydrophobic paint).

This bowl is connected to at least the urine outlet pipe 19 preferably leading to the interface of said organo-mineral bed and plant cover, the collected urine being then spread by means of the distribution pipe 19 previously described. Thus, traces of residual urine in the bowl are pushed back to the bed 7 and do not allow the release of odor.

The evacuation pipe 7 extends into the bed 7 of cover material according to a network 21 of urine dispersion on the bed 5 of chabasite material, here at the interface with the latter.

Said urine dispersion network 21 is configured to allow homogeneous dispersion of the urine on the bed of chabasite material, the pipe 19 being deployed in coils above the surface of the bed 5 and pierced with holes at less on part of its length. The arrangement of the holes is provided for this dispersion, for example more narrow towards the end of the pipe. If necessary, a urine delivery pump can be mounted on the urine pipe circuit 19. Other configurations may be envisaged, such as, for example, a parallel distribution or several crossed parallel circuits.

Said urinal 1 comprises a watertight container 23 for containing said beds of covering material 7 and material based on chabasite 5, advantageously adapted to the dimensions of these beds, and a support panel of said bowl 3.

A sealed liner configuration supports beds 5 and 7 may still be considered allowing the sanitary isolation of the whole. Thus, said urinal can be disposed at a convenient location for its use without being constrained by the presence of a water system for a conventional cleaning of the urinal.

The tray 23 due to the weight of the beds 5 and 7 is heavy enough to allow the holding in position of the urinal without resorting to important grounding work.

Moreover, one of the faces of said panel, accessible by means of steps 27 and an access surface 28, serves to allow the urination of a person discreetly through side baffles 29, while the face opposite can serve as advertising medium or message communication.

The panel face receiving the person will advantageously be covered with a hydrophobic coating and an upper promontory (not shown) forming a roof office to protect weather. This promontory may be equipped with a rainwater collection tank and a leaching gutter of said face, as well as solar collectors if the light input is deemed necessary.

In addition, said access 27, 28 may be part of the bed of material chabasite 5 so that the urine emitted outside the bowl 3 can be recovered directly by the latter and do not contribute to the emission of odor .

In addition, the presence of plants 9 in the tray adds an aesthetic or even ecological character to the device.

Naturally, the device can be extended to use by several people in a set (not shown) comprising a sequence of adjacent urinals such as that shown in 1, or in a set (not shown) comprising a single tray for containing said beds cover and chabasite and several support panels for urinal bowls.

Alternatively, the device may comprise at least one urinal removably mounted on the tray, for example comprise a bed of material based on chabasite extending at least on a portion of the surface of the tray which may be an earth barrier, a urinal, a platen fixed to the earth barrier (with the tray at its edges for example) and covering at least a portion of said bed of chabasite material.

The platen is configured to support said urinal (quick-mount, for example rotatably mounted and locking clip on the platen) on said tray above the bed of material chabasite, so as to allow at least one adsorption urine by said bed of chabasite material (by a flow of urine from the urinal on the bed through a passage in the platen). This flow is advantageously closed by a valve on the urinal, open only in service.

The urinal can still be mounted on at least one support panel removably mounted on the tray, for example by a set of mortises on the tray or plate. Thus, the device can be arranged with or without a urinal, said urinal being removably mountable on the plate (for example by means of a paddle) or the platinum urinal assembly being removably mounted on the tank or earth barrier, forming in the latter case a dirt-only scavenger adsorbing odors (including urine of dogs) and with its own vegetalized aesthetic character.

Furthermore, the urinal can be removed from the tray or platinum (or platinum urinal tray) a certain time in case of saturation of the device, the time it recovers from excess urine.

Said platinum can be a platinum aesthetic conformation, which makes the home more pleasant.

The invention thus brings a new application of a material based on chabasite to the treatment of urine collected by urinals in the city, namely to adsorb the nitrogenous materials of the urine (without odor) and to extract nitrates and water with a view to their natural regular elimination and excluding particular logistics through the growth of plants.
