Abstract

A continuous filtration device for industrial sludges and slurries comprises a continuous metal chain conveyor belt fed with magnetically susceptible filter granules e.g. steel balls to form a filter bed on the band. Sludge is run onto the filter, liquid percolating the bed to reservoir disposed below the band and solids forming a cake on the band. The terminal roller on the conveyor is fitted with an electromagnet retaining the filter granules on the band, the sediment falling away to collection reservoirs. The granules are subsequently sprayed off the band, away from the magnetic influence, and are returned to the filter inlet chute, washings being fed to the inlet slurry duct.
