Chamber filter plate is a modification of filter plate and frame. Two compacted plates create an individual chamber; filter cake produces on the plates in layer form. As the thickness of the cake increases, the permeability and flow rate decreases causing longer filtration cycles and higher operation costs.
During the later stage of filter cycle, high feed pressure is employed to dry the filter cake and this dewatering period is quite long. This period is usually called non-productive phase.
Chamber filter plates used alone are suitable for general applications where strict requirement of cake dewatering is not high.
However, combination of chamber plate and membrane plate will effectively shorten the filter cycle and save operation cost.
Features
Conical pips in recessed area not only support the filter cloths but also provide a drain path for the filtrate.
Diverse feeding methods satisfy different purposes, such as center feed, head feed, foot feed, corner feed and external feed. Other special feed arrangements can be customized for practical purposes.
High pressure filtration makes the percentage of moisture of the cake far lower.
Maximum filtration pressure is rated at 7 bar (101 psi) or 16 bar (232 psi).
Maximum working temperature is up to 120°C。
