Gravity Belt Filter*

A gravity belt filter is a device that is similar in general form to the horizontal belt filter except separation is induced wholly by gravitational forces. The normally flocculated feed is introduced at one end of a continuous, semi-permeable belt that moves around a sequence of rollers. During translation with the belt, the free water in the feed drains on the horizontally oriented portion of the belt to typically produce a 6 to 10 fold increase in concentration at the point of discharge from the belt.
