Belt Filter Presses. Belt Filters use pressure to the slurry to wring liquid out of the solid waste. Simply put, the sludge is fed through a series of tensioned belts, and high pressure and gravity separate liquids from the solid. Problems are encountered when the filter belt becomes blocked with solids or blinded by unwanted oils or grease.

When belt filter press works, the upper and lower tensioned filter belts carry the sludge layer, which passes through a series of rollers arranged regularly in a Sshape. The pressure and shear force on the sludge layer are formed by the tension of the filter belt itself, and the capillary water in the sludge layer is squeezed out to obtain mud cake with high solid content, thus realizing ...
