AK Automatic Disc Filter Introduction 

 Filtrascale full automatic disc filters using a specially designed disc filtration technology.  Thin color-coded   polypropylene discs are diagonally grooved on both sides to a specific micron size. A series of these discs are then stacked and compressed on a specially designed spine. When stacked, the groove on top runs opposite the groove below. The stack is enclosed in a corrosion and pressure resistant housing.

 During the filtration process, the filtration discs are tightly compressed together by the spring’s power and the differential pressure, thus providing high filtration efficiency. Filtration occurs while water is percolates from the outer diameter to the inner diameter of the element. Depending on the micron rating, there are from 18 (in 400micron discs) to 32 (in 20 micron discs) stopping points in each track, thus creating the unique in- depth filtration. 

Filtration Process

1, The discs are compressed together by both the spring and the pressure difference on the tightening cap, forming a sturdy filter element preventing solids breakthrough.

2,  Inlet water flows into the filter through the filter element

3,  The suspended solids in the water are trapped on and between the discs

Backwashing Process

A command from the control unit to the filter’s inlet valve causes the value to close the filter’ inlet and open the drain.

1,  Filtered outlet water enters from the opposite direction through the outlet port of the filter.

2,  The flaps of the membrane are opened by the water pressure, allowing the water to flow only into the 3 flushing pipes.

3,  The water is forced through nozzles built into the flushing pipes.

4,  Water from the flushing pipes also flows into the piston and pushed the tightening cap up,

   decompressing the filtration element discs

5,  Tangential jets of water cause fast spinning of the separated discs and remove the trapped solids.

6,  The solids are flushed from the filter to the drain
