| Self-cleaning Automatic Disc Filtration Systems from 2" To 14" |
 |
|
 |
Based on the long experience and reputation of AMIAD |
|
Systems configurable To any flow requirements and irrigation water
qualities
|
|
Due To special design of Amiad discs, the ADF is the most efficient system
of its kind
|
|
|
 |
|
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.

Water enters through the inlet pipe at the bottom part of the filter housing (2).
As the water enters the filter housing it is given a powerful "Cyclone" movement
by the turbine-like blades of the disc cleaning element in the base of the filter
chamber (3). As the water swirls, some of the dirt particles are thrown outward
To the wall of the filter housing To the upper part of the filter, where they remain²
until the Next flushing cycle (4).
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 (5). The stack of discs is held compressed by the piston at
its top (1). Clean filtered water flows out of the filter from the center outlet (6).

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 the 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 (7).
Rows of high pressure water jets direct a spray onto the discs which blasts
suspended material off of them and spins the stack of discs, throwing dirt and
flush water outward by centrifugal action (8).
This flushing also carries away suspended material which accumulated outside
of the stack as a result of the "Cyclone" cleaning effect.
The flush water passes out of the filter To the drain manifold.
At the End of the flush cycle, the direction of water reverses again, the piston
compresses the stack of discs, and the water flows in the filtering mode.
A flush cycle is Then initiated in the Next filter in the battery.
