HOW IT WORKS

GENERAL

The Arkal SK 2″ Compact filter is a stand-alone, automatic disk filter with a patented self-cleaning backwash mechanism. The filter is suitable for flow rates up to 20 m3/h with filtration degrees ranging from 20 to 400 microns. Inlet/outlet: 50 mm (2″) diameter.

THE FILTRATION PROCESS

Arkal’s specially developed disc filtration technology works with thin, color-coded polypropylene discs with a specific micron size. The discs are grooved diagonally on both sides, in opposite directions. A series of discs are compressed by means of a preloaded spring.

The grooves of two adjacent discs, pressed together, create a series of intersections that form multiple particle traps. During the filtration process, the force of the spring along with the differential pressure firmly compresses these discs, providing exceptional filtration efficiency. Filtration occurs when water flows from the outside to the inside of the filter element. Depending on the micron range, there are multiple crossing points in each lane, providing exceptional depth filtration.

3 TYPES OF BACKWASH ARE POSSIBLE

  1. With your own filtered water
  2. With water from external broon
  3. With compressed air

1. THE BACKWASH PROCESS.

Activated by a predetermined time setting or set differential pressure, the system switches to backwash mode. The inlet valve closes while the flush outlet valve opens. During the backwash process, the pressure is released and the piston rises, releasing the pressure on the discs. Filtered water is then forced through the nozzles placed along the frame with discs. At this stage, the discs spin freely, loosening the stuck particles and then washing them away.

Note: During the backwash of the 2″ Compact, the flow of filtered water is interrupted.

2. EXTERNAL SOURCE BACKWASH (WITH WATER FROM EXTERNAL SOURCE)

The inlet and outlet valves as well as the outlet and supply are opened and closed automatically. Pressurized water from an external source enters the filter through the outlet valve and flushes the filter.

ADVANTAGE: Higher performance for low operating pressure applications and high degree of fine filtration

3. AIR AIDED BACHWASH (WITH COMPRESSED AIR)

ADVANTAGES:

  • Improved cleaning power, especially at fine filtration grades
  • Minimized rinse water volume
  • Low pressure operation
  • Reduced rewind time per filter element (<10 sec)
  • The air and water mixture at a minimum pressure of 2.5 bar generates the optimum cleaning performance in SpinKlin™ technology.
