Chamber Plate Product Features

Technical Information

In a conventional recessed chamber filter press, the filter cake is formed in layers until the chamber is completely filled with solids. As the filter cake is being formed, its permeability and flow rate decreases as the solids increase in the chamber, causing the feed pressure to rise.
The recessed chamber filter plate design allows their use in more wide ranging applications than flush plates and frames due to the larger feed eye input and higher filtrate output capacities. Slurries with higher densities are acceptable. Higher feed and discharge velocities are also achievable with this plate type. The recessed chamber plate has a much stronger design which affords operation at higher temperatures and pressures compared to flush plates and frames.
The recessed chamber filter plate also lends itself to adding elastomer gaskets around the periphery and discharge eyes, so that with inclusion of internally install media, improved sealing between chambers is achieved.
However, highly compressible products can reduce the cake permeability to such a degree that it creates longer filtration cycles and increased operating costs.
The unproductive phase of the pressure filtration cycle, where the flow rates are already greatly reduced, can be replaced by squeezing with membranes, improving the overall productivity of the application
