Hydrotech Discfilters

Hydrotech Discfilter

The Hydrotech Discfilter is a mechanical and self-cleaning filter that offers a large filter area in a small footprint.

How it works

► The water to be treated flows by gravity into the filter segments from the centre drum. Solids catch on the inside of the filter panels mounted on the two sides of the disc segments.

► As the solids catch on the inside of the filter media impeding the flow of water through the disc, the water level inside the discs begin to rise, triggering a level sensor to start the disc to rotate and a backwash cycle begins.

► High pressure rinse water wash the solids off the filter media into the solids collection trough. Typically the backwash requires 0,05-3% of the total filtered water flow.
