ABSTRACT:
In horizontal belt filter apparatus wherein the belt is progressed by alternate incremental motion of the upper run and the lower run, wash liquor used for washing the belt in the lower run, e.g. by spraying into a wash box, is recycled and used for washing filter cake on the upper run at several spaced apart locations. Also, in the upper run, a respective compression device is arranged subsequent to each supply of wash liquor in the direction of travel of the upper run, and during compression gas is blown into the filter cake through the pressure plate of each device so as to maximise extraction of liquid. Trays mounted below the belt are connected to vacuum during stationary periods of the upper run and are arranged to ensure separate collection of liquid for successive sections of the upper run, which liquid may optionally be recycled to upstream locations.
