Digested - Spiral Brush Screen Filter - Brochure

The wastewater to be filtered flows into the top of the unit where it enters the interior of the cylindrical screen. Clarified material, or filtrate, exits the unit by passing through the screen while the solids accumulate inside the screen. The motor spins a spiral-shaped cleaning brush within the screen, keeping the screen clean and pushing the accumulated solids to the purge outlet at the bottom of the unit. An automated valve opens periodically to discharge these solids out of the unit—there is no disruption to the process flow and no shut down time for backwashing.
