  The installation contains ion-exchange FU1L.trts 1, inlet 2 and outlet 3 collectors, pipelines 4, connecting INPUT-filters with an inlet collector, pipelines 5, connecting the outlet of the filters with the outlet collector. The inlet manifold 2 through the valves 6 by the source water pipeline 7 is connected to the main pipeline 8 of the source water. The discharge manifold 3 through the valves 9 by pipeline 10 of purified water is connected to the main pipeline 11 of purified water. The discharge manifold 3 through the drainage pipe 12, the section of which with shut-off valves 13 is located vertically, is connected to the main drainage pipeline 14. The vertical positioning of the pipeline is necessary to eliminate stagnant zones. The main drainage pipe 14 is connected through a shut-off valve 15 to sewage pipelines and through a stop valve 16 by a pipe 17 to the inlet of the tank 18 for reuse of wash water. The outlet of the tank 18 is connected to the suction of the loosening pump 19, the pressure line of which is connected to the main pipeline of the loosening water 20. The main pipeline 20 of the loosening water through pipe 21, the section of which with the stop valve 22 is vertically attached to the diverting collector 3. Main The regeneration pipeline 23 through the pipeline 24, the section of which with shut-off valves 25 is located vertically, is connected to the inlet manifold 2. To the inlet manifold 2 through the drainage pipe water 26, whose section with fittings 27 is located vertically, is connected to the main drainage pipeline 28. A switching unit 29 containing stop valves 6, 25, 27 is installed on the inlet

the collector 2 and the switching unit 30 containing the check valves 9, 13, 22 are installed on the outlet collector 3. The switching nodes 29 and 30 are intended to switch the collectors to the main pipelines. Valves 25 and 27 in switch unit 29 are vertically aligned with collector 2 and valve 13 and 22 in switch unit 30 are installed vertically with respect to collector 3, the latter, at the water inlet from the filter, in front of valve 9 to collector 3 drainage pipe 12 with fittings 13, which is done to eliminate stagnant zones in the pipelines and to prevent the regeneration of the new solution from entering the chemical-cleaned line.

20 water.

The operation of the plant consists of three modes: water purification, recovery and reserve. Switching nodes 29 and 30 ensure the operation of the installation in all modes.

In the first mode (water purification), valves 6 and 9 are opened. The source water from the main pipeline 8 through the source water pipeline 7, the supply manifold 2 and pipelines 4 are fed to filters 1 where the water is being cleaned. The purified water through pipelines 5, the discharge manifold 3 and the pipeline 10 of purified water is directed to the main pipeline 11 of the purified water. In the process of operation, the units loaded into the filters are depleted and lose their ion-exchange capacity. Exhausted

the installation is deactivated

 water tap - valve 6 closes and

9. The entire filter block is disabled for restoration.

The second mode of operation (recovery) is divided into a series of steps. Pearl

- vyy stage on restoration - loosening of the filtering material. At this stage, the loosening is carried out with pulmonary water according to the scheme: valves 22 and 27 are opened and loosening water

50 from the tank 18 by the pump 19 through the main pipeline 20 of the loosening water, the pipeline 21, the collector 3 and the pipelines 5 are fed to filters am 1, from which the loosening water is diverted

55 through pipelines 4, the collector 2, the drainage pipe 26 and the main pipeline 28 down the drain.

The second stage of recovery is the regeneration of depleted material. During regeneration, the valves 22 and 27 are closed, the valves 25, 13, 15 are opened. The regeneration solution from the main pipeline 23 through pipeline 24, collector 2 and pipelines 4 is fed to filters 1, from which the spent regeneration solution through pipelines 5, collector 3, pipeline 12 and the pipeline 14 is discharged into the sewer. The regeneration is completed by closing the fittings 25, taking into account that the regeneration solution remaining in the collector 2 and pipelines 4 will be forced out of them by washing water in the next stage and pass through the filters.

The third stage of recovery - washing the filter material from the products of regeneration. Washing is carried out in two stages. In the first

the stage wash water is discharged into the sewer. At the same time, valves 6, 13, 15 are opened. The wash water from the main pipeline 8,

5 through pipeline 7 of the source water, through the collector 2, pipelines 4 are fed to filters 1, from which wash water through pipelines 5, collector 3, the drainage pipeline 12 and the main pipeline 14 are heated, are drained. In the second stage, the wash water is collected in the reuse tank; for this purpose, the valve 16 is opened, the valve is closed.

15, round 15 and washing water through line 17 are directed to tank 18. At the end of the washing, valves 6, 13, 16 are closed. The unit is ready for operation.

20 The third mode (reserve) occurs when the unit is not required to be put into operation. All valves on the unit are closed.
