Disk filters Аrkal

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.

Operating principle

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.

Cleaning

Because of the bumps, the disks have tiny spaces between them when stacked together. The water is forced between the disks, and the particulates are filtered out because they won't fit through these gaps. The organics are snagged by the sharp points on the bumps. For automatic cleaning of the filter the disks are separated from each other which frees the debris to be flushed out through a flush outlet. For manual cleaning, you must remove the disks and hose them off.

Filters of this type are installed before the system to prevent mechanical particles to get into the system.

Warranty: 2 years. The service life of the disc set on the urban water - up to 10 years!
