CLEANING PROCESS

Waterborne particles entering the filter are captured on the outer surface of a compressed disc stack, forming a layer of contaminants. This buildup causes the pressure differential between the filter's inlet and outlet to increase. The system automatically initiates a backwash cycle based on one of two user-defined triggers configured on the control panel: when the pressure differential reaches a preset: value, or after a pre-determined time interval has elapsed, whichever occurs first. Upon activation, a three-way valve reverses the water flow direction and opens the discharge line. The pressurized water from the outlet acts on an internal spring mechanism, releasing the compression on the discs and allowing them to separate. This reverse flow, combined with the grooved design of the discs, causes them to spin and effectively flushes the accumulated particles from their surfaces out through the drainage line.

WORKING PRINCIPLE

Water enters the filter and passes through the Disc stack. During operation, contaminants accumulate on the outer surface of the discs. This buildup obstructs the water flow, creating a pressure differential between the filter's and outlet, When this pressure differential reaches a threshold of 0.7 bar, a cleaning cycle is required, which can be initiated either manually or automatically.
