FILTRATION PROCESS
Water enters the filter through an inlet and passes through the coarse screen that functions as a first stop for large particulate. Water then reaches the fine screen, which further purifies the flow by separating smaller particles from the water. As more water flows through, impurities build up on the fine screen. As impurities on the screen accumulate, a pressure differential builds up between the internal section of the fine screen and its external section.
BACKFLUSHING PROCESS
When the difference in pressure reaches the preset value on the differential pressure indicator, a series of events is triggered while water continues to flow to the system units. The flushing valve opens, and water flows to drain. Pressure in the hydraulic flushing chamber and the dirt collector is significantly lowered resulting in a suction process via the suction nozzles to the dirt collector and from there through the flushing valve to drain. The electric motor simultaneously rotates the dirt collector and moves it along its axis. The combination of the linear movement and rotation efficiently cleans the entire internal screen surface. The flushing cycle continues as long as the pressure difference between the inlet and outlet remains the same and according to signals from the controller. If the pressure difference remains unchanged for a fixed preset time, the emergency flushing valve opens along with the normal flushing valve. The flushing cycle continues for the time that was preset on the controller. The flushing valves close when the pressure difference drops. The operation of the electric motor is stopped after the collector axis reaches a limit switch. The filter is now ready for the next cycle, with clean and filtered water flowing through the outlet.
