Self-cleaning filter features: continuous water supply is carried out in the backflush, and the whole backwash is achieved in every point of the suction net filter. The anti-flushing is only a small local pressure change between the suction nozzle and the fine filter screen, while the movement of the collector and hydraulic cylinder does not affect the normal water supply. At the same time, the amount of water consumed during the backflush is very small, with the flow rate of 300m3/ h. For example, the reverse flushing flow rate is 35-40m3 / h, the anti-flushing time is 7-15 seconds, and the backwash amount is 80-160L
