membrane squeezing

How Membrane filter press do 2nd time filter press
Membrane filter plates have a chamber below the drainage surface that may be inflated. The common method used is water pressure, which is generated by pumping into the squeeze cavity to inflate the face of the plate against the filter cake. Air may also be used.
Membrane plates are used to reduce the cake moisture content or shorten the filtration cycle time. Two types of membrane plate designs are used, fixed membranes and replaceable membranes. Mixed pack membranes are the most common configuration (one recessed plate, then one membrane plate alternate in the press plate pack). The final product produces savings in the overall plate pack cost.
