Description

Water regeneration facility gray

The present invention aims at a installation for gray water regeneration through the filtering and sterilizing of water from secondary uses (domestic uses such as those from sinks and showers) for reuse on devices that do not require potability of water, such as watering gardens or toilet tanks.

Since times not very far the requirements Domestic and industrial water have been growing at a very rapid pace high. In addition, rainfall is suffering a rhythm falling. It is common that throughout the summer many municipalities, particularly Spanish municipalities suffer water restrictions due to water scarcity.

The problem is compounded because the water Drinking is used, in addition to primary uses (human consumption) and secondary, for tertiary uses, such as irrigation of gardens, or toilet tanks, which do not require a high Water quality grade.

There are other devices that treat quality of the water. However, they are either unsatisfactory for use. that they are intended to give or their installation is excessively expensive and disproportionate to the result that is intended to be obtained.

It is intended, then, by applying this invention, treat the water from secondary uses for provide sufficient quality to be used with guarantees in tertiary uses.

Brief description of the drawings

In order to illustrate the explanation that will follow, we attach to the present specification, two sheets of drawings in which: in two figures the essence of the present invention, and in which:

Figure 1 shows a schematic view of a treatment tank as part of the installation of the invention, and

Figure 2 schematically shows the complete installation with the set of devices that the make up.

Detailed description of the invention

As described and represented, the installation of the invention comprises a tank comprising two sections, a gray water inlet section (9) in which produces the reception of water and in which there is a sandblasting and  degreasing, and a treatment and disinfection section (11), a absorption-drive pump (7), and possible and preferably a post-filtering device (3).

This installation also includes an entrance (1) to the water tank to be treated, an outlet (2) from the tank towards the discharge pump (7) and an overflow outlet (8) (12) of the deposit.

As a means of treatment and disinfection, uses an ozone supply device, which comprises the minus an ozone production device (16), a conduit (22) of ozone conduction produced to treatment section and disinfection (11), and one or more ozone diffusers (18), located normally close to the base of the deposit.

In accordance with the preferred embodiment represented, the water intake takes place from the entrance (1) located at the top of the entrance section (9) of the warehouse through the inlet duct (17). The water may be previously treated by a solids filter. Once enters said input section (9) the sandblasting and the degreased In this area a deposition of particles occurs in the lower zone and possibly a leak, as well as and a flotation of light products (fats and foams) towards the part  higher.

In said input section (9) a collection duct (14), provided with a collection mouth (13). The collection mouth (13) will be located at medium height, preferably above the outlet of the inlet duct (17). From this way the solid particles will precipitate down and not they will enter the collection duct or they will do it in much smaller measure.

When the installation is at rest the water gray from secondary uses is accessing the section of entrance, raising the water level, possibly provided with floating elements and heavy particles. Obviously, the floating particles will float and heavy particles will go to background. When the maximum level is reached the water height will reach the height of the overflow (12) and any influx by above that level it will be evacuated to a general drain (5) through from the overflow outlet (8).

The collection duct (14) is superiorly finished off in an introduction duct (15) in the section of treatment and disinfection (11), preferably horizontal or down (downstream). When the water level in the input section is above the lower maximum level of said collection duct (14) or the introduction duct (15), which is higher, the water will fall by gravity inside said treatment and disinfection section (11). Therefore the Water level in the inlet section (9) will be permanently the of the maximum height of the collection ducts (14) or of introduction (15). It is planned that the introduction duct (15) comprise a non-return valve or clapper (10).

When there is a consumption requirement, the pump (7) will be connected by partially or totally emptying said section of treatment and disinfection (11), but leaving the area of entry, until there is new influx, at which time the excess will be poured into the treatment and disinfection zone (11), until the filling of this one. When said zone (11) is full, if there is new influx of gray water, the level in the entrance area will continue to rise, until it reaches the overflow height, thus producing the emptying of the surplus, and first of all floating elements, thus facilitating an improvement in the quality of the reused water

Preferably, the pump output is directed to a post-filtering device (3), with a consumption output (4) and, desirably a return output (6) to drain (5) in cleaning operations.

According to a preferred embodiment, the deposit, particularly the treatment and disinfection zone (11), comprises a gas evacuation mouth (24). That mouth of gas evacuation (24) comprises a conduit provided with a activated carbon filter (19) and a conduction to a controller ozone in air (20). When the ozone level is higher than the maximum permissible, the controller commands the device stop ozone generator (16).
