How the 2”- 3” Spin Klin™ Systems Filters Work

General
The Arkal 2”- 3” SpinKlin™ series are modular, all polymeric, automatic disc filters with a patented self-cleaning backwash mechanism.
The 2”- 3” SpinKlin™ systems range in flow rates from 10 m3/h (44 gpm) to 200 m3/h (880 gpm) with filtration degrees ranging from 20 - 400 micron. Inlet/Outlet from 80 - 200 mm (3”- 8”) 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 system enters backwash mode. The inlet valve port shuts as the drain valve port opens. 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.
During the flushing cycle each filter pod is backwashed sequentially, while the other pods continue to supply filtered water downstream. When a pod begins the backwash cycle, the system valves automatically reverse the flow in the pod, allowing filtered downstream pressurized water to backwash the filter.
