The Filtertech Model SF dewatering sludge filter automatically separates loose liquid from solids, to ease the burden of disposal and to minimize makeup and replacement costs of valuable process liquids.

Mode of Operation

As the slurry is fed into the pool area, the high differential pressure created by the vacuum producer draws liquid through the disposable media, creating a cake of solids. The media is advanced either by liquid level or timer and the cake is positioned over the liquid extraction chamber for the dewatering phase. The recovered liquid is then returned to the system or sent to drain.

The dewatered solids and spent media are discharged for disposal or recovery. An optional media rewinder/separator is available.
