Solid/liquid filtration can be accomplished by various techniques, such as centrifuges, rotary drum vacuum filters, belt filter presses, recessed chamber filter presses, membrane filter presses or by thermal cake drying in the filter press.
Quite often, the final selection of a filtration method is determined by the requirement for the degree of dryness of the filter cake and the quality of the filter cake composition.

FILTER PLATE & FRAME TECHNOLOGY The oldest and most well known method of solid/liquid separation is the use of filter plates and frames. In history, filter plates and frames were made of wood and today, like all other filter plate systems they are made of plastic. |  |
 |
CHAMBER FILTRATION TECHNOLOGY In a conventional recessed chamber filter press the filter cake is formed in layers until the chamber is completely filled with solids. | |
 |
»WELDED« MEMBRANE FILTER PLATE TECHNOLOGY The membrane filter technology provides considerably better cake quality and increased cake dry solids. The final dewatered cake is a result of mechanical squeezing by the membrane. | |
 |
»REPLACEABLE« MEMBRANE FILTER PLATE TECHNOLOGY All of the advantages and experience of the welded membrane filter plate design are retained in the development of the replaceable membrane filter plate. The membrane can be easily replaced without taking the plate out of the filter press. | |

THERMAL CAKE DRYING The latest development is the system of thermal cake drying, which combines the advantages of mechanical pre-dewatering and thermal cake drying within the filter press. | |
