Working Principle
The water entering the filter passes through the coarse screen and passes to the area where the fine screen filter is located. The water continues to flow from the fine screen to the outlet and creates a layer of pollution on the inner surface of the fine screen and this pollution causes a pressure difference at the inlet and outlet of the filter. The dirty layer on the screen surface causes difficulty on the water flow. This flow difficulty creates a pressure difference between the inlet and outlet. The difference value is detected by the ΔP sensor and transmitted to the control unit to start the washing.
The Control Unit opens the motorized valve. While the motorized valve is discharging the dirty water; the control unit activates the motor. The circular movement of the gearmotor ensures a helical movement on the suction nozzles which are on the collector assembly make. The transmission of the movement is made with a square gear shaft. The movement of the reducer motor is controlled by optical sensors. Thus, the screen surface is completely scanned and the dirty layer is cleaned. The absorption of the dirty layer is made by the nozzles, as the system that opens to the atmosphere creates a vacuum effect in the filter. The sucked particles pass through the cover body by the collector assembly and are discharged out from the (3) discharge section. The collector set returns to its starting position and continues the washing while returning also. The relief valve is closed and the cleaning process is completed. The filtration process is not interrupted during backwashing.
