Gravity Belt Filter

Gravity Belt Filter

Gravity Bed Filters are continuous self-cleaning gravity filters. Solids are removed as liquid flows through the filter media and are then discharged in a relatively dry condition into an outside container.

An endless conveyor carries the blanket type filter media. As unfiltered liquid flows onto the filter media it passes through the blanket and deposits solids on the media surface (thus forming an additional filtering stage.

When solids particles accumulated appreciably slows the rate of liquid flow through the filter media, a motor driven conveyor belt is advanced, dumping waste filter media into a holding box and bringing a section of fresh media into position under the liquid flow.
