Hydrotech Beltfilter

Hydrotech Beltfilter reduces sludge volumes

The Hydrotech Beltfilter is made for efficient filtration and draining of sludge and wastewater. It is an automatic, self-cleaning filter specially designed to achieve optimal performance in systems where high solids content in the dewatered sludge is essential.

How it works

Beltfilters are perfect for handling high concentrations of suspended solids that cannot be handled by disc filters or drum filters.

Sludge or wastewater is led into the filter 1 and passes by gravity through the filter belt 2.

The belt is designed as a slowly moving conveyer installed in a stainless steel tank. As the water passes through the filter, the filtering process ensures the efficient removal of particles. These particles are drained on the belt to a high dry matter content. The dewatered sludge is removed at the top of the filter 3 and discharged through a hopper 4 for final treatment.

Backwash System: Dewatered sludge is scraped off the belt which is then cleaned by a high-pressure water rinse system. (backwash unit retracted for visibility)

The belt is further cleaned by a high-pressure backwash system 5 and the rinse water is led either back to the process or to further treatment.

The Beltfilter is normally operated intermittently (demand) controlled by a level switch.
