The filter cake forms on top of the belt and can undergo further treatment by washing (co-current or counter-current), steaming, extraction or vacuum drying. The wash filtrates can be recovered individually from each process step and further processed without any cross-contamination. The belt filter discharges the filter cake at the discharge roller. The cloth is cleaned as the belt travels back.
