High productivity

The raw water enters the filter via the inlet flange and flows through the filter element from the inside to the outside. The solids in the raw water are retained on the outside of the filter element. The purified water leaves the filter through the clean water outlet.

Backwashing

A differential pressure measurement in the raw water inlet and the clean water outlet determines the degree of contamination of the filter element. At a defined differential pressure, the backwash process is activated. An adjustable time relay in the electrical control system additionally enables the backwash process. At the start of filter cleaning, the motor-driven backwash valve opens, generating atmospheric pressure in the backwash line and the flushing window in the filter housing. Due to the excess pressure inside of the filter element on the clean water side, the solids retained on the outside of the filter element are now forcibly backwashed into the atmosphere against the direction of filtration.

The rotation of the filter element guarantees the 100% cleaning of the filter surface. The flushing process is complete after 15-20 seconds and the backwash valve is closed automatically. Filtration is not interrupted during backwashing.
