Definitions
- the invention relates to a method and a device for * regulating the hardness of water for a dwelling, in particular comprising an osmosis unit or a filtration device or an ultrafiltration device.
- an osmosis or filtration device or ultrafiltration device discharges into 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” or "treated water”.
- the inventions described in the documents cited above are suitable for reverse osmosis purifiers without water discharge for domestic use that do not have a sewage system.
- 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.
- 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.
- the document WO 2015/010219 describes a method and a device for treating a city and / or source water in which "pure water” is mixed with water that is not yet treated in a random way. This way of doing things does not guarantee the hardness of the water supplied to the house.
- the invention aims to provide a method and a device for regulating the hardness of water for a home, in particular comprising an osmosis unit or a filtration device or an ultrafiltration device, rejecting no water during filtration but recycling and recovering the discharge water of an osmosis or ultrafiltration, while supplying the whole house with water having only a small amount of dissolved limestone, in other words a water having a hardness of between 8 ° and 12 ° French, according to the minimum standards
- the single figure shows a diagram of a device for regulating the hardness of water for a dwelling according to the invention.
- the supply water of the house arrives via a pipe 10 and passes through a pressure reducer 1 1, 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 22 for the mixing of water.
- This device can be purchased from "ROBINEX SA" at CH-5035 Unterenfelden, for example under the name "Interpass”. Said apparatus 12 being modified by the inventor with regard to a valve valve 15.
- the apparatus 12 comprises a first valve 13, which makes it possible to bring water through a conduit 23 into a device dynamic storage 19.
- the dynamic storage device 19 is constituted by a flexible hose wound on itself in a coil.
- Vmax x (D / 2) 2 xl.
- L device 12 has in its central part a valve valve 15 calibrated at 1 bar difference valve valve added by the inventor to the device "Interpass", which allows "pure water” to mix with water feeding the house so as to have a hardness of between 8 ° to 12 ° French and a stabilized pH between 6.8 and 7.4.
- the apparatus 12 comprises an adjustment screw 22 making it possible to obtain the desired hardness
- the valve 14 controls the input circuit to supply the dwelling via the line 17.
- the pressure of the drinking water will be controlled by a device 18 which will maintain it at 4 bars.
- the water arriving via the pipe 10 passes from the block 12 in the dynamic storage device 19 through the conduit 23 as indicated by the arrows drawn next to the ducts in the drawing.
- the water in the conduit 23 receives from the conduit 24 of "pure water” before being introduced into the dynamic storage device 19.
- "Pure water” arriving via the conduit 24 comes from a purification circuit of the water through the ducts 5 and 21.
- the water purification circuit comprises a pump 9, an anti-clogging device 1, for example as described in document WO 86/04887, an osmosis unit 2 having a membrane 3 and a settling filtration device 6.
- the water 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 through the conduit 5 into a conduit 21 and then through the conduit 24 into the conduit 23 to terminate in the device. dynamic storage 19 while waiting to be used or to be reinjected into the purification circuit.
- the water purification circuit consisting of a duct 4 fed with the water discharged by the osmosis unit 2, or by a filtration device or an ultrafiltration device, and is injected into a decantation filtration device 6, found in commerce and within the reach of the skilled person. Then the water through the conduit 8 will be mixed with the water leaving the dynamic storage device 19 through the conduits 20 and 25 in the pump 9. There is provided on the conduit 25 an anti-return valve 7 preventing water circuit purification system to enter the housing supply circuit 17.
- 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 building materials. It will be advantageous to equip the decantation filtration device 6 with filters of 25 ⁇ or less than 25 ⁇ .
- the restarting of the pump 9 will be done as soon as the sensor 26 detects a hardness TH greater than the hardness limit TH 0 . This restarting will generally take place only in the case of additional introduction of untreated feedwater at line 23.
- the hardness limit TH 0 will be between 80 and 120 ppm, and preferably will be equal to 100 ppm.
- a consumption of water will be made in the house “pure water” will leave the dynamic storage device 19 by the conduit 20 will enter the block 12 through the conduit 16 and the valve 14, said "pure water” will be mixed with feed water by a setting screw 22 ensuring the mixing of water for a hardness of between 8 ° to 12 ° French and a stabilized pH between 6.8 and 7.4, according to the standards in force.
- the ducts 6, 20 and 25 will be connected together by means of a junction 27a T.
- This junction 27a T will be disposed at a distance d from the mixing block 12, d being advantageously equal to or greater than 2.5 cm. Indeed, it was found that, in the case where the junction 27a T is positioned less than 2.5 cm from the mixing block, a water flow could occur between the outlet of the conduit 16 and the entrance of the conduit 23 via the mixing block 12, thus disrupting the general operation of the device according to the invention.
- the ducts 23 and 24 will be connected together by means of a T junction 27b, said junction being advantageously arranged at least 2.5 cm from the mixing block 12.
- the device according to the invention makes it possible to supply a house with water in accordance with current standards.
