REVERSE OSMOSIS DEVICE WITH FLOW RECOVERY SHELVED

Object of the invention

5

The object of the present report is a reverse osmosis device with recovery of the discarded flow, produced during osmotic filtration and its subsequent injection into the domestic plumbing network, said volume of water being able to be used for other diverse uses, such as, for example, for use in tanks, showers, appliances, etc.

Background of the invention

At present, a variety of household osmosis devices are known in the state of the art, whose purpose is to obtain low water

15 mineralization, and they implement a fairly similar operating method.

Basically, the operation of these devices is based on a physical phenomenon, through which two fluids of different concentration separated by a semipermeable membrane (porous structure with holes the size of a few micrometers),

20 filters the particles at the molecular level. In this way, it is possible to separate two solutions (one with greater saturation than another) at the same barometric pressure, with said semipermeable membrane, the water of the least saturated solution will pass to the most saturated.

Thus, by applying a higher barometric pressure to the higher solution

25 saturation, the membrane will allow the passage of the solution of greater saturation to that of less saturation, with the proviso that only liquid molecules will pass, but not the suspended or dissolved particles therein. This process is known as "Reverse Osmosis."

The problem with this type of process is that it rejects a large amount of water, which is wasted, is wasted without control, and is not used for other uses.

To alleviate this problem, the applicant is aware of the existence of the Spanish utility model ES 1 067 790 that describes a device for the use of wastewater in domestic reverse osmosis equipment of the type comprising several previous filters, an osmotic membrane and a pressurized tank where water is stored

purified for consumption through the corresponding additional faucet, characterized in that the wastewater utilization device is composed of an auxiliary reservoir in which the residual water from the reverse osmosis accumulates, equipped with an outlet that channels the water again to the previous filters of the equipment of reverse osmosis, and an entrance of drinking water coming from the network, to compensate the consumed water of the pressurized tank.

Said utility model improves the state of the art, but it has the main drawback that, by reusing the excess water from the osmotic process, mixed with water from the supply network, it causes a greater saturation of the membrane, which inexorably causes that it is clogged with greater assiduity and therefore, has to be replaced more frequently, and therefore, increases maintenance costs ostensibly, in addition to reducing the quality of the water obtained by the treatment.

Description of the invention

The technical problem that the present invention solves is to achieve a reverse osmosis device that allows to take advantage of the water flow rejected by the osmotic filtration process, deriving said flow to the plumbing network, thus taking advantage of the volume of water paid by the user. For this, the reverse osmosis device with recovery of the discarded flow, object of the present utility model memory, is characterized in that it comprises means for filtering the flow of the water received from the water supply network (improving its qualities as to suspension of particles, odors and flavors), and that manages to optimize, the water rejected by the osmosis cycle integrated in it, and can be reused in the plumbing network of the home in question.

Thanks to its use, the device presented here, will allow an almost total use of the water resources contracted, not discarding water flow, which can be used in processes that do not require a higher quality of water, such as, for example, the use of appliances, showers or similar. Thus, the user can use the rejected or discarded water, at any point of the installation, as if it were water from the commercial supply network.

In this way, the purpose of the device will be the optimization of the rejection of saturated water by the reverse osmosis equipment or system known in the state of the art, which have ranges between: 1: 2 in equipment with pressure pump and new membrane; until 1:12 at the end of the cycle of use of the mentioned membrane in equipment without pump

5 pressure.

Taking into account that generally reverse osmosis devices are of greater use in areas where water is scarcer, the high ratio between the water consumed and the water rejected is the main problem for the purchase of these

10 devices

More specifically, the reverse osmosis device with recovery of the discharged flow, object of the present specification, is characterized in that it comprises a connection valve to the water supply installation of the dwelling (1), which is connected to a valve bypass (2) used for filling the device during commissioning and / or periodic maintenance of the device, and where, in turn, said valve (2) is connected to a first pressure switch (3) associated with a pressure gauge 35 (4) and a first solenoid valve (5) responsible for regulating the flow of water

5 osmosis, composed of a container body of the sediment filter (7), which allows the filtration of clay, mud and plant particles from water; and with a container body of Carbon filter (8), responsible for removing odors and flavors from water.

The first solenoid valve (5) is connected to a second pressure switch (14) or

10 rejection pressure switch, in charge of measuring the pressure of the rejection circuit, prioritizing the filtration of osmotized water against the injection of rejected water in the housing water installation. Associated with said second pressure switch (14) is an injection pump (13) responsible for taking the water from the rejection tank (12) and increasing its pressure until it reaches at least the water pressure of the water installation of the

15 housing The rejected water is in two connection points with the domestic plumbing network: a first connection point (23) between the end of the rejected water pipe and the start of the osmosis system pipe; and a second connection point

(24) in the conduit that connects the assembly to the domestic network, thus coexisting the rejected water with the water of the plumbing network and the by-pass duct (2).

20 The tank (12) will be connected to a flow regulator or restrictor (11) that restricts the rejection flow, to optimize the functioning of the membrane.
