The filter press is an installation in which the product to be filtered is pressed in filter chambers between vertically hanging filter plates each covered with a filter cloth. Depending on the desired outcome a chamber filter press or a membrane filter press is used.
Filter presses achieve the highest separation efficiency of all mechanical separation techniques, by pressing the sludge in closed chambers . For this, the finest filter fibers may be used to guarantee an optimal product separation. It is, therefore, the preferred technique for industries focusing on the maximum purity of the filtrate, or the lowest residual moisture in the cake .
Both the extraction of the solid matter (the “filter cake”) as well as the purification of the original product may be important. The liquid content or water content in the filter cake depends on the physical and chemical properties of the suspension as well as on the final pressure of the feed pump at the end of the filtration cycle .
