Abstract
L’eau est d’abord introduite par une première pompe (9) dans un premier circuit, présentant un dispositif anti colmatage (1). Le dispositif anti-colmatage est suivi d’un osmoseur (2) ou d’un dispositif de filtration ou d’un dispositif d’ultrafiltration. Puis «l’eau pure» sortie de l’osmoseur ou du dispositif de filtration ou du dispositif d’ultrafiltration est introduite par une deuxième pompe (20) dans un réservoir accumulateur (19), tandis que l’eau rejetée par l’osmoseur ou le dispositif de filtration ou le dispositif d’ultrafiltration est filtrée et décantée est réinjectée dans le premier circuit avant la première pompe (9), enfin «l’eau pure» dudit réservoir accumulateur est introduite dans un second circuit alimentant toute l’habitation.The water is first introduced by a first pump (9) in a first circuit, having an anti-clogging device (1). The anti-clogging device is followed by an osmosis unit (2) or a filtration device or an ultrafiltration device. Then "pure water" from the osmosis unit or the filtration device or the ultrafiltration device is introduced by a second pump (20) into an accumulator tank (19), while the water discharged by the reverse osmosis unit or the filtration device or the ultrafiltration device is filtered and decanted is reinjected into the first circuit before the first pump (9), finally "pure water" said accumulator tank is introduced into a second circuit feeding the entire dwelling .
Description
[0001] L’invention concerne un procédé de traitement d’une eau de ville et/ou de source pour une habitation comportant un osmoseur ou un dispositif de filtration ou un dispositif d’ultrafiltration. The invention relates to a method for treating a city water and / or source for a dwelling comprising an osmosis unit or a filtration device or an ultrafiltration device.
[0002] Dans son principe, un osmoseur ou un dispositif de filtration ou un dispositif d’ultrafiltration rejette à l’égout autant d’eau, et même parfois beaucoup plus, chargée en minéraux qu’il ne produit d’eau osmosée ou filtrée ou ultrafiltrée, dénommée par la suite «eau pure». In principle, an osmosis or filtration device or an ultrafiltration device discharges the sewer as much water, and sometimes even more, loaded with minerals that it produces osmosis water or filtered or ultrafiltered, hereinafter referred to as "pure water".
[0003] Une perte d’eau aussi importante, quand on connaît le coût de l’eau, n’est plus admissible. A significant loss of water, when we know the cost of water, is no longer admissible.
[0004] Il est connu par les documents FR 2 979 339 et FR 2 979 628, qui ont pour titre: «Dispositif destiné à optimiser des purificateurs d’eau par osmose inverse sans rejet d’eau à usage domestique et permettant de supprimer la plupart des interventions de maintenance» et «Dispositif permettant le rinçage au moyen d’eau purifiée des membranes des purificateurs par osmose inverse sans rejet de rinçage, donc spécialement adapté aux osmoseurs sans rejet d’eau». It is known from documents FR 2 979 339 and FR 2 979 628, which are entitled: "Device for optimizing water purifiers by reverse osmosis without water discharge for domestic use and to remove the most maintenance interventions "and" Device for rinsing with purified water the membranes of reverse osmosis purifiers without rejection of rinsing, so specially adapted to reverse osmosis without water discharge ".
[0005] Les inventions décrites dans les documents cités ci-dessus sont adaptées aux purificateurs par osmose inverse sans rejet d’eau à usage domestique qui ne possèdent pas de circuit de mise à l’égout. Toutefois les dispositifs décrits dans les documents français, cités ci-dessus, ne tiennent pas compte de la qualité de l’eau nécessaire aux canalisations, aux lave-vaisselles et aux machines à laver le linge, notamment en ce qui a trait au calcaire. En effet, les dispositifs décrits fournissent de «l’eau pure» qu’à un robinet, alors que le reste de la maison est alimenté en eau pouvant être chargée de calcaire. The inventions described in the documents cited above are suitable for reverse osmosis purifiers without discharge water for domestic use that do not have a sewage system. However, the devices described in the French documents, cited above, do not take into account the quality of water needed for pipes, dishwashers and washing machines, especially with regard to limestone. In fact, the devices described provide "pure water" only at a tap, while the rest of the house is supplied with water that can be loaded with limestone.
[0006] L’invention a pour buts de fournir un procédé et un dispositif de traitement d’une eau de ville et/ou de source pour une habitation comportant un osmoseur ou un dispositif de filtration ou un dispositif d’ultrafiltration, ne rejetant aucune eau lors de la filtration, mais recyclant et récupérant l’eau de rejet d’un osmoseur ou d’une ultrafiltration, tout en alimentant la maison en eau ne présentant qu’une faible quantité de calcaire dissous autrement dit une eau présentant une dureté comprise entre 8° et 12° français, selon les normes minimales conseillées OMS. The invention aims to provide a method and a device for treating a city water and / or source for a dwelling comprising an osmosis unit or a filtration device or an ultrafiltration device, not rejecting any water during filtration, but recycling and recovering the discharge water of an osmosis or ultrafiltration, while supplying the house with water having only a small amount of dissolved limestone, in other words a water having a hardness included between 8 ° and 12 ° French, according to the minimum standards recommended WHO.
[0007] Ces buts sont atteints avec un procédé de traitement d’une eau de ville et/ou de source selon l’invention définie à la revendication 1 et avec un dispositif pour sa mise en œuvre selon l’invention définie à la revendication 3. These objects are achieved with a method of treating a city water and / or source according to the invention defined in claim 1 and with a device for its implementation according to the invention defined in claim 3 .
[0008] L’invention sera mieux comprise et ses caractéristiques apparaîtront plus clairement à la lecture de la description de réalisations données à titre d’exemple en regard du dessin annexé dans lequel: The invention will be better understood and its characteristics will appear more clearly on reading the description of embodiments given by way of example with reference to the accompanying drawings in which:
[0009] La figure unique représente un schéma d’un dispositif pour le traitement d’une eau de ville et/ou de source selon l’invention. The single figure shows a diagram of a device for the treatment of a city water and / or source according to the invention.
[0010] Comme on le voit sur le schéma représenté sur la figure unique, l’eau de ville et/ou de source arrive par une conduite 10 et passe par un réducteur de pression 11, qui réduit la pression à 4 bars. Ensuite elle arrive sur l’appareil 12. L’appareil 12 est un bloc qui comprend trois vannes 13, 14 et 15, un clapet de sécurité et une vis de réglage pour le mélange des eaux, cet appareil peut être acheté chez «ROBINEX SA» à CH-5035 Unterentfelden, par exemple sous le nom «Interpass», ledit appareil 12 étant modifié par l’inventeur en ce qui concerne une vanne clapet. Sur la partie gauche sur le dessin l’appareil 12 comprend une première vanne 13, qui permet de faire entrer l’eau de ville et/ou de source dans un premier circuit par une pompe 9. L’appareil 12 a dans sa partie centrale une vanne clapet 15 tarée à 1 bar de différence,(vanne clapet ajoutée par l’inventeur à l’appareil «Interpass») et par la suite une vanne 14 qui permet à «l’eau pure» de se mélanger avec l’eau de ville et/ou de source de manière à présenter une dureté comprise entre 8° à 12° français et un ph stabilisé entre 6,8 et 7,2, et d’entrer dans un second circuit pour alimenter l’habitation par la conduite 17. La pression de l’eau de consommation sera contrôlée par un appareil 18 qui la maintiendra à 4 bars. As seen in the diagram shown in the single figure, the city water and / or source arrives via a pipe 10 and passes through a pressure reducer 11, which reduces the pressure to 4 bar. Then it arrives on the apparatus 12. The apparatus 12 is a block which comprises three valves 13, 14 and 15, a safety valve and an adjusting screw for the mixing of water, this apparatus can be purchased from "ROBINEX SA To CH-5035 Unterentfelden, for example under the name "Interpass", said apparatus 12 being modified by the inventor with respect to a check valve. On the left side of the drawing the apparatus 12 comprises a first valve 13, which allows the city water and / or source water to enter a first circuit by a pump 9. The apparatus 12 has in its central portion a check valve 15 calibrated at 1 bar difference, (check valve added by the inventor to the "Interpass" device) and thereafter a valve 14 which allows "pure water" to mix with the water city and / or source so as to have a hardness of between 8 ° to 12 ° French and a ph stabilized between 6.8 and 7.2, and to enter a second circuit to feed the house by driving 17. The pressure of the drinking water will be controlled by a device 18 which will maintain it at 4 bars.
[0011] L’eau arrivant par la conduite 10, passe du bloc 12 dans la pompe 9, comme indiqué par les flèches tracées à côté des conduits sur le dessin. La pompe 9 envoie l’eau sous une pression de 8 bars dans un dispositif anti colmatage 1, par exemple comme décrit dans le document WO 86/04 887. À la sortie du dispositif anti colmatage 1 l’eau de ville et/ou de source est envoyée dans un osmoseur 2 présentant une membrane 3, mais pourrait aussi être envoyée dans un dispositif de filtration ou dans un dispositif d’ultrafiltration. «L’eau pure» sortant de l’osmoseur 2 ou du dispositif de filtration ou du dispositif d’ultrafiltration, est envoyée par la conduite 5 dans une pompe 20, qui la pousse par la conduite 21 dans le réservoir 19 avec une pression de 5 bars, où elle sera stockée en attendant d’être utilisée. The water arriving through the pipe 10 passes block 12 into the pump 9, as indicated by the arrows drawn next to the ducts in the drawing. The pump 9 sends the water under a pressure of 8 bar in an anti-clogging device 1, for example as described in the document WO 86/04 887. At the outlet of the anti-clogging device 1 the tap water and / or The source is sent to an osmosis unit 2 having a membrane 3, but could also be sent to a filtration device or to an ultrafiltration device. "Pure water" leaving the osmosis unit 2 or the filtration device or the ultrafiltration device is sent via line 5 to a pump 20, which pushes it through line 21 into reservoir 19 with a pressure of 5 bars, where it will be stored while waiting to be used.
[0012] Le premier circuit étant constitué par une conduite 4 alimentée par l’eau rejetée par l’osmoseur 2, ou par un dispositif de filtration ou un dispositif d’ultrafiltration, et sera injectée dans un dispositif de filtration décantation 6, (que l’on trouve dans le commerce et à la portée de l’homme de métier), puis par la conduite 8 sera mélangée à l’eau de ville et/ou de source dans la pompe 9. Il est prévu sur la conduite 8 un clapet anti retour 7 empêchant l’eau de ville et/ou de source d’entrer dans le premier circuit. Ce premier circuit fonctionnera jusqu’à que le réservoir accumulateur 19 soit plein. Le dispositif de filtration décantation 6 sera vidé régulièrement des déchets sans perte d’eau et lesdits déchets seront séchés et utilisés pour notamment pour faire des matériaux de construction. The first circuit consisting of a pipe 4 fed with the water discharged by the osmosis unit 2, or by a filtration device or an ultrafiltration device, and will be injected into a decantation filtration device 6, (that it is commercially available and within the reach of those skilled in the art), then by the pipe 8 will be mixed with tap water and / or source in the pump 9. It is provided on the pipe 8 a non-return valve 7 preventing city and / or source water from entering the first circuit. This first circuit will operate until the accumulator reservoir 19 is full. The decantation filtration device 6 will be regularly emptied of waste without loss of water and said waste will be dried and used especially for making construction materials.
[0013] Aussi longtemps que le réservoir accumulateur 19 n’est pas plein l’eau circulera dans le premier circuit et aucune eau ne sera rejetée à l’égout. Dès qu’une consommation d’eau sera fera dans la maison «l’eau pure» sortira du réservoir accumulateur 19 par la conduite 16 entrera dans le bloc 12 par la vanne 14, ladite «eau pure» sera mélangée à de l’eau de ville et/ou de source par une vis de réglage assurant le mélange des eaux pour une dureté comprise entre 8° à 12° français et un ph stabilisé entre 6,8 et 7,2, selon les normes en vigueur. Il est de plus prévu une vanne clapet 15, tarée à un bar de différence, dans le bloc 12, pour les cas où il y aurait une très grande consommation dans l’habitation. As long as the accumulator tank 19 is not full water will circulate in the first circuit and no water will be discharged to the sewer. As soon as a consumption of water will be made in the house "pure water" will leave the accumulator tank 19 by the pipe 16 will enter the block 12 by the valve 14, said "pure water" will be mixed with water of town and / or source by a setting screw ensuring the mixing of water for a hardness of between 8 ° to 12 ° French and a ph stabilized between 6.8 and 7.2, according to the standards in force. There is further provided a valve valve 15, calibrated at a difference bar, in the block 12, for cases where there would be a large consumption in the home.
[0014] Comme on peut le constater on dispose d’un dispositif simple, donc bon marché, ne rejetant aucune eau à l’égout et facile à régler. Le dispositif selon l’invention permet d’alimenter une habitation en eau conforme aux normes actuelles. As can be seen we have a simple device, so cheap, not rejecting any water in the sewer and easy to adjust. The device according to the invention makes it possible to supply a house with water in accordance with current standards.
