The Diemme-NFM Recessed Chamber and Membrane Diaphragm Filter Press is a batch filter with vertical filter plates. It is used when the filter cake resistance is high, the particle size distribution is fine, and production rates and cake moisture cannot be achieved with vacuum air flow.
The filter press allows for quick filling of chambers, thorough counter-current cake washing, individual cake discharge, and filter fabric washing.
Standard recessed filter plates, designed for the optimum cake thickness, rely on the filter feed pump to dewater the cake in individual chambers. Membrane plates are also recessed but utilize an expandable diaphragm to support efficient cake washing and dewatering of the filter cake.
Finally, mixed packs of membrane plates alternating with standard recessed chamber plates for cake washing and discharging are often used as an economical solution. Additional features include automatic cloth washing, cake discharge measurement, full automation controls.
