Self-Cleaning process

The controller, which may be set to trigger the cleaning cycle by pressure differential, time, or both, operates hydraulic valves in the inlet which change the direction of water flow in the filter. This reverse flow initiates the self cleaning process.
Clean water now enters from the center of the disc element. Water pressure acts on the piston, lifting it from the stack of discs, allowing the discs to separate from one another.
Rows of high pressure water jets direct a spray onto the discs which blast suspended material off of them and spin the stack of discs, throwing dirt and flush water outward by centrifugal action.
This flushing also carries away suspended material which accumulated outside of the stack as a result of the "Vortex" cleaning effect. The flush water passes out of the filter to the drain

Filtering process

Water enters through the inlet pipe at the bottom of the filter housing.
As the water enters at the base of the filter chamber it passes through "fin plate" blades which force the water to enter the filter chamber with a Vortex effect. As the water swirls within the filter chamber, some of the dirt particles are forced outward and upward and collect on the wall of the upper part of the filter chamber, where they remain until the next flushing cycle.
The water flows from the outside of the disc stack to the inside, passing along the specially designed grooves on the surface of the discs which catch the suspended material. The stack of discs is held compressed by the piston at its top. Clean filtered water flows out of the filter from the center outlet.


The ADF is an automatic self-cleaning plastic disc filter. Its self-cleaning mechanism is triggered
by pressure differential or timer for 100% cleaning of the disc element.
