How the SK 2” Compact Filters Work

General
The Arkal SK 2” Compact filter is a stand alone, polymeric, automatic disc filters with a patented self-cleaning
backwash mechanism.
The Arkal SK 2” Compact filter is for flow rates of up to 20 m3/h (88 gpm) with filtration degrees ranging from
20 – 400 micron. Inlet /Outlet - 50 mm (2”) diameter.

The Filtration Process
The discs are stacked on the SpinKlin™ spine and assembled according to pre-determined water filtration
requirements. During filtration, the discs are compressed by means of a pre-loaded spring and differential
pressure, forcing the water to pass through the grooved disc surface, thus trapping the solids.

The Backwash Process
Activated by a pre-determined time command or differential pressure, the filter enters backwash mode. The inlet
valve port shuts as the drain valve port opens. Water flows through a bypass filter screen into the outlet valve and
into the filter. During the backwash process, pressure is released and the spine’s piston elevates, releasing the
compression on the discs. Tangential jets of filtered water are then forced through the nozzles positioned along
the spine. At this stage the discs spin freely, loosening the trapped solids which are then flushed out.
*Please note: During backwash of the 2” Compact downstream flow is suspended.
