Drum Thickener/Drum Filter

The Drum Thickener/Drum Filter from Stjernholm is well-suited for filtering and separating particles already in the inlet

The Drum Thickener / Drum Filter from Stjernholm is particularly well-suited for filtering and separation of particles as early as in the purification plant inlet, from the sand washer section, or for concentration of sludge from process and purification tanks.

It is constructed as a closed casing with a drum which has been mounted with a perforated plate made of stainless steel or polyester woven filter.

The drum, which rotates on 2 wheels and a bearing is driven by a gear motor. The drum can be driven by a frequency converter that ensures an optimal rotation speed.
