Each hydrocyclone 8 (9) is provided with a mesh filter 21 and sedimentary camera 22.

Hydrocyclones 8 and 9 are hydraulically connected in parallel with the tank 1 through the pipes 16 and 17, 23 and 24, 25 and 26 and the switch 10 modes of the filter. The switch 10 is connected by pipes 27 and 28 with the punch is 0 modes of operation of the filter is provided with a possibility of rotation around the axis of symmetry of hydrosaluric 29 and sleeve 30, mounted in the housing 31 (see Fig.2-4). The casing 31 is divided into sections 32, 33, 34 receiving and supplying raw water (32), directions of purified water (33) into the pipeline 7 drip irrigation systems and drainage (34) food contamination and colmatage in system 6 irrigation by flooding.

Section 32 of the receiving and supplying raw water is connected by pipes 5, 25, and 26 with a pump station 15 and hydrocyclones 8 and 9 when the supply of raw water.

Section 33 of the directions of purified water are hydraulically connected by pipes 27 and 28 with slotted or perforated pipe 3 mounted in the tank 1 filter material 4, and a flange with a trunk pipeline 7 drip irrigation systems.

Section 34 of the tap of products of pollution and colmatage pipelines 23, 24 is in communication with the sediment chambers 22 of the hydrocyclone 8, 9 and 6 irrigation flood irrigation water.

Mentioned hydrosaluric 29 in each section 32-34 has a radially oriented channels 35, 36, 37 equal flow area. On the surface of the sleeve 30 hydrosaluric 29 mating with the housing 31 of the switch 10 of the modes of operation of the filter, the channel 38, the connecting section 32 of the receiving untreated water from an open pond with section 33 towards the handle 39 of the switch. Position handle hydrosaluric 29 is made to be secured to the housing 31 of the switch 10 for the following cases filter: - water purification (see Fig.2); - delete colmatage of filtration material 4 and products pollution from sediment chambers 22 cyclones 9 and 10 (Fig.3); - locked position of all systems (Fig.4); - the supply of water from the pumping station 15 in the system of irrigation by flooding; - the supply of water from the pumping station 15 in the pipeline 7; - submission of chlorine-containing gas into the vessel 1 through the filtration material 4.

Filter drip irrigation system operates as follows.

The filter will look at examples of the most typical modes of execution of the main and auxiliary production processes.

When filter mode water purification for submission to the dropper operator handle 39 with hydrosilation 29 in the housing 31 moves from the position "d" to position "a" (see diagram in Fig.1). Hydrosaluric 29 in the sleeve 30 and the housing 31 of the switch 10 will occupy in sections 32, 33 and 34 to the position shown in Fig.2.

When operating the pump station 15 (see in conjunction Fig.1 and 2) water from an open pond floating valve 20 by a flexible sleeve 19 and the valve 18 under pressure supplied to the pressure truboprokatniy of 11 gauge control system. In section 32 of the water, combining the channels of the housing 31 and the sleeve 30 is fed in radially oriented channels 35 gidrologiya 29, and through them is directed into the pipes 25 and 26 for supplying raw water to the blocks of hydrocyclones 8 and 9. Last hydraulically connected in parallel with a capacity of 1.

When receiving the diverted water from an open pond and feeding tangentially to the inner wall of the body of the hydrocyclone 8 (9), the mass of water is given a rotational movement around its vertical axis of symmetry.

Due to gravitational forces and centrifugal forces mist mineral Sora and vegetable impurities clinging to the inner wall of the housing of the hydrocyclone 8 (9), fall in the direction of the sediment chamber 22. Water molecules with the smallest particles penetrate into the cavity filter 21, and from him received into the pipeline 16 (17). The pipes 16 and 17 water after primary treatment enters through cracks in the pipe 2 into the tank 1. Water is discharged into the tank 1 above the filtration material 4. Water molecules under pressure in the tank 1 are punched through the pores of the filtration material 4 and accumulate in the bottom part of tank 1. From the tank 1 purified water is drained and sent to the cavity perforated pipes the purified water into the pipeline 7 drip irrigation system (see Fig. 2). The pipes 27 and 28 to radially oriented channels of the housing 31 and the sleeve 30 clean water flows through the channels 36 in hydrosaluric 29 and one of them is displayed in the main pipe 7 for feeding a drip in irrigation pipelines, linearly placed in the irrigated field.

In the described position (a) hydrosaluric 29 radially oriented channels of the housing 31 and the sleeve 30 of the switch 10 of the modes of operation of the filter is closed by hydrosilation 29 (see Fig.1 and 2).

After prolonged use of the filter material 4 in the tank clogged with fine particles of silt, mineral and plant litter, algae and microorganisms. High ambient temperature and periodic filter in drip irrigation system lead to intense activity of fungi. The entire filtration material is subjected to clogging. To restore performance of the filter without replacing the filtration material by removing colmatage operator handle 39 hydrosaluric 29 moves from position "a" to position "b" (see Fig.1 and 3).

In this case, hydrosaluric 29 section 32 of the receiving untreated water from an open pond closes radially oriented channels in the sleeve 30 and the housing 31 perenapravlenija purified water. From the channel 38 radially aligned channels of the housing 31 and the sleeve 30 untreated water enters the cavity hydrosaluric 29, and from it extended channels 36 is directed into the pipes 27 and 28. Last hydraulically connected through the collector with a perforated drainage piping 3. In the tank 1 in the filtration material 4 is created the counter. Suspended solids and sediment from the filtration material 4 washed untreated water filed under the greatest pressure pump station 15. Dirty water with particles and fine debris, algae, microorganisms through the cracks of the pipeline 2 is discharged by the pipes 16 and 17 in the cavity of the hydrocyclone 8 and 9. Dirty water transit in cavities strainer 21 is directed into the sediment chamber 22 and carries away the products of pollution of bottom parts of the hydrocyclone 8 and 9 and the shortest path through pipelines 25 and 26 is directed to section 34 of the tap of products of pollution and colmatage. Combined channels of the housing 31 and the sleeve 30 of the switch 10 and radially oriented channels 37 hydrosaluric 29 water is discharged into the system 6 irrigation flood irrigation water. This system, as a rule, peasant and individual farms combined with the planting of the volume of water in system 7, the operator handle 39 hydrosaluric 29 moves to the position "e", specified on the housing 31 of the switch 10 of the modes of operation of the filter.

For irrigation by flooding, bypassing the tank 1 and hydrocyclones 8 and 9, the operator handle 39 hydrosaluric 29 combines with a grade of "f" on the housing 31 of the switch 10.

To destroy microorganisms in sedimentary chambers 22 of the hydrocyclone 8 and 9 and in the filtration material 4 of the tank 1 in the last overpressure serves chlorine gas. In this case the switch 31 connects the sleeve of a high pressure cylinder and the handle 39 is switched to the position "K" (see Fig.1).

This is achieved by improving the performance of the filter and water treatment quality and reduce maintenance costs.

Uninterrupted operation of the filter provides a supply of purified water droppers address each planted the plant in a protected or outdoors and, as a consequence, increasing yields and reducing their cost.
