CLASSIFICATIONS OF FILTER PRESS

  • PLATE & FRAME FILTER PRESS

    Plate and frame filter press is the most fundamental design among all the other filter presses, and majority nowadays refer it as “membrane filter plate”.

  • AUTOMATIC FILTER PRESS

    It consists of larger plates and frames filter presses with mechanical “plate shifter”. The function of the plate shifter is to move the plates and allow rapid discharge of the filter cakes accumulated in between the plates. It also contains diaphragm compressor in the filter plates which aids in optimizing the operating condition by further drying the filter cakes.

  • RECESSED PLATE FILTER PRESS

    Recessed plates are made up of polypropylene squares with concave depression and a hole in the center. Two plates join together to form a chamber to pressurize the slurry and squeeze the filtrate out through the filter cloth lining in the chamber. However there are disadvantages to this method such as longer cloth changing time, unable to accommodate filter papers as well as the possibility of forming uneven cake.
