The filtration process of a water filter

Raw water flows into the filter cartridge from the inlet and then passes through the filter barrel from the inside out. Impurities are intercepted on the inner wall of the filter cartridge, and the filtered clean water flows out from the outlet. As the impurities accumulate on the inner wall of the filter cartridge, a filter cake is formed on the inner surface of the filter cartridge, gradually creating a pressure difference between the inside and outside of the filter cartridge. When the pressure difference reaches the preset value of the pressure difference controller, the self-cleaning process will be initiated.
Self cleaning process
The self-cleaning process of a water filter relies on a suction scanner and a drain valve that move in a spiral motion along the inner surface of the filter cartridge. The opened drain valve generates a high backwash flow rate at the front end of the suction scanner's nozzle and creates a vacuum. The filter cake attached to the inner wall of the filter cartridge is sucked out and discharged from the body. The entire cleaning process takes about 60 seconds, and the system does not stop flowing during cleaning. The suction scanner of the S series has a point by point scanning function, making cleaning more thorough.
Control mode
The self-cleaning filter is equipped with three functions: differential pressure/time/manual operation. At the same time, we have specially designed a priority control function for you, which means that in any situation, as long as the system pressure difference reaches the predetermined value, the equipment will start the self-cleaning function to better ensure the normal operation of your system.
