Arkal Spin Klin Disc Filters (Back Washable)
Arkal Disc Filters are washable pre-filters that will extend the life of the filters that follow it. If your water is visibly dirty then adding a disc filter as a first stage is highly recommended.
Disc Filtration Technology (Manufacturers Information: http://www.arkal-filters.com)
Arkal Water Filtration Systems operate using a specially designed disc filtration technology. Thin, colour-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 to the groove below, creating a filtration element with a statistically significant series of valleys and traps for solids. 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 percolating from the peripheral end to the core of the element. Depending on the micron rating, there are from 18 (in 400 micron discs) to 32 (in 20 micron discs) stopping points in each track, thus creating the unique in-depth filtration.
Benefits:
Keep in mind:
-
The disc filter does not filter the water finely enough for bacteria or heavy metals
-
The disc filters are brought in as needed, as a result there is a lead time of typically 7 to 15 working days before the Disc Filters will be ready for collection or delivery.
Spin Klin vs standard disc filters
The standard and industrial size arkal disc filters are manually washable, which means that when the cartridge becomes full you must open the housing, pull out the cartridge, physically wash it under a tap and then place the cartridge back inside of the housing.
The spin klin disc filters remove the need to manually wash the disc filter cartridge, by allowing you to backwash the disc filter cartridge inside of the housing itself.
