Arkal’s disc filtration solutions carry out depth and surface filtration leading to high particle holding capacity, effective cleaning and consistent filtration results.

Arkal’s unique disc filtration and backwash technology uses thin, color-coded discs of varied micron sizes. The discs are grooved on both sides, in opposite directions, creating a series of crossing points that trap the particles, thereby creating a depth filtration element. Each filter assembly in a multi-unit system is cleaned individually, allowing the other filters to continue operating during the backwash process.
