How the Super Galaxy Works

The Super Galaxy filter is based on Arkal’s Spin KlinTM disc filtration technology which is a modular, automatic, self cleaning filter designed for high flow rates and may be installed either vertically or horizontally. With its unique grooved disc, depth filtration technology and patented self cleaning mechanism, Spin KlinTM filters cover a wide range of industrial, marine, municipal and agricultural applications from 400 to as fine as 20 micron filtration degrees.
Each filter contains multiple filtration spines on which the Spin KlinTM discs are stacked. These thin, color-coded polymeric discs are diagonally grooved in opposite directions on both sides to a specific micron size. When mounted on the spine, the discs’ grooves form a matrix of consecutive stopping points letting the water pass through while stopping suspended solids. A tightening cylinder compresses the discs by a preloaded spring, piston and differential pressure, ensuring accurate filtration degree with no possibility of breakthrough.

The Filtration Process
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. Water percolates through the filter element from its outer to its inner diameter. Suspended solids are trapped on and between the discs while filtered water flows out through the filter’s outlet port.
The Self-Cleaning Process
The gradual build-up of particles on the discs causes a pressure differential to develop across the system. At a pre-set level a signal from the PD Switch starts the self-cleaning cycle. An electric command reverses the flow direction through the filter, the compression springs of the filter modules are released; the spine pistons rise up releasing the pressure on the discs.

High pressure tangential jets of filtered water are pumped at high velocity through the nozzles at the center of the spines causing the discs to spin free and clear. The retained and trapped solids are quickly and efficiently flushed out to the drain. On completion of its pre-programmed cleaning time (approximately 15 seconds) the filter returns to filtration mode. The system continues to filter until another backwash cycle is triggered by time-interval, PD switch or by a combination of the two.
