Abstract

Autonomous use of recycled water in detached, semi-detached and terraced housing. The system is based on a chamber which collects water from the siphon traps, and also water from washing machines, air conditioning units and roofs. The water passes from this chamber to an underground tank equipped with a purification kit consisting in a unit comprising an impeller pump preceded by a second mesh filter and immediately followed by a sand filter. The pump is activated automatically by means of level sensors driving the purified water to a raised tank from where the water descends to the toilet cisterns of the house and to non-drinking water outlets located in the garage or garden.

Description

APROVECHAMIENTO AUTÓNOMO DE AGUAS RECICLADAS EN CHALET, VIVIENDA ADOSADA O PAREADA AUTONOMOUS USE OF WATER RECYCLED IN CHALET, TOWNHOUSE OR PAREADA
La presente invención se refiere a un sistema de reciclado de aguas residuales domésticas por el que se utilizan tanto en casas tipo chalet como en viviendas adosadas o pareadas u otro tipo de edificaciones parecidas las aguas procedentes de las duchas y bañeras, de los lavabos y de los bidés, así como las de Ia lavadora, el lavadero y las procedentes de Ia lluvia y del agua de condensación de los aparatos de aire acondicionado para el llenado de Ia cisterna y consiguiente limpieza del inodoro, para Ia limpieza general del chalet, en concreto para el lavado de suelos, lavado de vehículos, además del riego de zonas verdes y en algunos casos para alimentar de agua Ia lavadora. Se encuadra dentro del campo de instalaciones de aguas no potables y de fontanería presentes en cuartos de baño, cocinas, aseos y zonas exteriores o ajardinadas de viviendas tipo chalet y otras casas unifamiliares, incluyendo tanto el sistema de evacuación de aguas residuales domésticas, como todos aquellos elementos que como el bote sifónico y las conducciones de desagüe del cuarto de baño permiten que con Ia instalación de un depósito subterráneo o aljibe, bomba de presión, un depósito elevado, filtros y rejillas para Ia depuración sean recicladas por una vez las aguas procedentes de los botes sifónicos de los cuartos de baño y de aseo que recogen el agua de las bañeras, duchas, lavabos y bidés de Ia casa, el agua de Ia lavadora y el agua de condensación de los aparatos de aire acondicionado o el agua de lluvia para su utilización como descarga de Ia cisterna del inodoro, limpieza de suelos, lavado de vehículos y riego de jardín. Se excluyen las instalaciones de agua sanitaria potable.The present invention relates to a system for recycling domestic wastewater whereby both water from showers and bathtubs, washbasins and toilets are used in both chalet-type houses and semi-detached or semi-detached houses or other similar buildings. the bidets, as well as those of the washing machine, the laundry and those coming from the rain and the condensation water of the air conditioning devices for filling the tank and consequent cleaning of the toilet, for the general cleaning of the chalet, specifically for the washing of floors, washing of vehicles, in addition to the irrigation of green areas and in some cases to feed water the washing machine. It falls within the field of non-potable water and plumbing installations present in bathrooms, kitchens, toilets and outdoor or landscaped areas of chalet-type homes and other single-family homes, including both the domestic wastewater evacuation system, as all those elements that, like the siphoning canister and the drain pipes of the bathroom, allow the installation of an underground tank or water tank, pressure pump, a high tank, filters and grids for purification to be recycled once the water coming of the siphonic boats of the bathrooms and toilets that collect water from the bathtubs, showers, sinks and bidets of the house, the water from the washing machine and the condensation water from the air conditioners or the rainwater for use as a discharge of The toilet cistern, floor cleaning, vehicle washing and garden irrigation. Drinking water facilities are excluded.
Son conocidas distintas instalaciones semejantes a Ia de Ia invención, básicamente aquellas que constan de un depósito en el subsuelo de un edificio de viviendas que recoge las aguas procedentes de bañeras, duchas y lavabos de todo el edificio para bombearlas a un depósito en el techo del mismo desde donde son conducidas a las cisternas de los inodoros. Producen el mismo efecto: un ahorro en el consumo de agua, ya que en los dos casos las cisternas de los inodoros funcionan con aguas usadas, pero no son sistemas autónomos como el que propone Ia presente invención. Es decir, sistemas cuyo circuito de aguas comienza y termina en Ia misma vivienda. Otras instalaciones y dispositivos controlan de un modo complejo (incluso electrónicamente) el flujo de una única bomba situada poco antes del bote sifónico, y de ahí es llevada a Ia cisterna del inodoro de modo que según cada una de las disposiciones de Ia misma hay un flujo distinto; aunque Ia versatilidad de estos sistemas en cuanto a número de flujos distintos es superior al de Ia invención, el coste y desarrollo de los mismos así como Ia complejidad hacen que no suelan ser muy usados en Ia práctica. Otras variaciones son las que aprovechan el agua procedente de Ia lavadora y Ia propia bomba de ésta para impulsar agua a Ia cisterna.Various facilities similar to that of the invention are known, basically those consisting of a deposit in the basement of a residential building that collects water from bathtubs, showers and sinks throughout the building to pump them to a tank on the roof of the same from where they are taken to the toilets cisterns. They produce the same effect: a saving in water consumption, since in both cases the cisterns of the toilets work with wastewater, but they are not autonomous systems like the one proposed by the present invention. That is, systems whose water circuit begins and ends in the same house. Other facilities and devices control in a complex way (even electronically) the flow of a single pump located shortly before the siphon canister, and from there it is taken to the toilet cistern so that according to each of the provisions of the same there is a distinct flow; Although the versatility of these systems in terms of the number of different flows is greater than that of the invention, their cost and development as well as the complexity mean that they are not usually used in practice. Other variations are those that take advantage of the water coming from the washing machine and the pump itself to drive water to the tank.
Se conoce también un sistema autónomo de aprovechamiento de aguas pensado tan sólo para un cuarto de baño de una vivienda de bloque de pisos o apartamentos que difiere de Ia presente invención en que su circuito alcanza tan sólo a un cuarto de baño o de aseo, y no a toda Ia vivienda, incluidas las aguas de lluvia y las de condensación como el aquí propuesto.It is also known an autonomous system of water use designed only for a bathroom of a house of apartment or apartment block that differs from the present invention in that its circuit reaches only a bathroom or toilet, and not to the whole house, including rainwater and condensation water as proposed here.
La instalación y el mecanismo de Ia invención tiene una misma funcionalidad con determinadas características estructurales distintas a las instalaciones y mecanismos anteriormente mencionados, y con Ia particularidad de Ia simplicidad en cuanto al conjunto de piezas y al montaje de las mismas.The installation and the mechanism of the invention has the same functionality with certain structural characteristics different from the aforementioned installations and mechanisms, and with the particularity of simplicity in terms of the set of parts and their assembly.
También constituye un conjunto que es independiente de por sí, es decir, adaptable a cuartos de baño, aseo, lavadoras, aparatos de aire acondicionado y desagüe de azoteas o tejados ya existentes sin grandes modificaciones. Además, Ia mayor parte de las piezas pueden ser fabricadas de materiales convencionales, con el buen grado de mantenimiento y conservación que suponen los mismos en este tipo de conjuntos.It also constitutes a set that is independent of itself, that is, adaptable to bathrooms, toilets, washing machines, air conditioners and existing roof or roof drains without major modifications. In addition, most of the pieces can be manufactured of conventional materials, with the good degree of maintenance and conservation that they entail in these types of assemblies.
Una de las más significativas ventajas de Ia presente invención frente a las conocidas es que en ésta Ia depuración es autónoma, realizándose sobre las propias aguas de Ia vivienda individual, siendo éstas aguas las únicas que se usan por segunda vez o reciclan. Esta ventaja contrasta con el inconveniente de usar en una vivienda aguas que a pesar de estar relativamente depuradas, proceden de otra vivienda con Ia consiguiente desconfianza para el consumidor que ello conlleva.One of the most significant advantages of the present invention over the known ones is that in this one the purification is autonomous, being carried out on the waters of the individual housing, these waters being the only ones that are used for the second time or recycled. This advantage contrasts with the inconvenience of using water in a house that, despite being relatively purified, comes from another house with the consequent distrust for the consumer that this entails.
Otra ventaja es que no se utilizan aguas que contengan o puedan contener materias orgánicas, tales como las aguas procedentes del inodoro, del fregadero o del lavavajillas. La vivienda constaría de dos redes de alcantarillado, una interna de reciclaje, que es Ia que recoge las aguas usadas para conducirlas al aljibe o depósito y otra red de alcantarillado normal, que es Ia que conduce las aguas del inodoro, fregadero y lavavajillas a Ia red general de alcantarillado. La presente invención se constituye a partir de una arqueta general que recoge las aguas procedentes de los botes sifónicos de Ia vivienda, es decir, de las bañeras, duchas, lavabos y bidés, además de las aguas procedentes de lavaderos , lavadoras, equipos de aire acondicionado y azoteas o tejados de Ia vivienda. De esta arqueta general pasa el agua a través de un filtro de rejilla a un depósito subterráneo para reciclaje de aguas provisto de un kit de depuración consistente en un conjunto compuesto por una bomba impulsora precedida de un segundo filtro de malla y seguida inmediatamente de un filtro de arena que también puede ser de carbón activado. La bomba es activada automáticamente por medio de sensores de nivel impulsando el agua depurada a un depósito elevado de agua no potable. De este depósito cae el agua por su peso a las cisternas de los inodoros de Ia casa, a puntos de agua no potable situados en el garaje o lugar reservado para el aparcamiento de los coches, en el jardín, en porches, suelos y para riego de jardín.Another advantage is that no water is used that contains or may contain organic materials, such as water from the toilet, sink or dishwasher. The house would consist of two sewage networks, an internal recycling one, which is the one that collects the water used to take them to the cistern or reservoir and another normal sewer network, which is the one that conducts the water from the toilet, sink and dishwasher to the general sewerage network. The present invention is constituted from a general casket that collects the water coming from the siphonic boats of the house, that is, from the bathtubs, showers, washbasins and bidets, in addition to the waters coming from laundry, washing machines, air equipment conditioning and roofs or roofs of the house. From this general cassette, the water passes through a grid filter to an underground water recycling tank provided with a purification kit consisting of a set consisting of a booster pump preceded by a second mesh filter and immediately followed by a filter of sand that can also be activated carbon. The pump is activated automatically by means of level sensors driving the purified water to an elevated tank of non-potable water. From this deposit the water falls by its weight to the cisterns of the toilets of the house, to points of non-potable water located in the garage or place reserved for car parking, in the garden, on porches, floors and for irrigation of garden.
La cisterna del inodoro consta de dos entradas de agua, una prioritaria que es el agua redolada procedente del depósito superior y una segunda para el caso en que falte agua reciclada, en cuyo caso entra agua de Ia red.The toilet cistern consists of two water inlets, one priority being the red water coming from the upper tank and a second one in the case where there is a lack of recycled water, in which case water enters the network.
