Arkal Water Filtration Systems

Disc Filtration Technology

Arkal Water Filtration Systems operate 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 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) to32 (in 20 micron discs) stopping points in each track, thus creating the unique in-depth filtration.
