Membrane and Chamber Filtre-Presses

Chamber filter press is the most common type of filter presses, which are used chamber filter plates. Filtering occurs in the space formed between two adjacent plates. The volume of the filter depends on the depth of the chambers. Chamber plates are generally made from high strength polypropylene and have high performance. Chamber filter presses are used in cases if the process requires only mechanical separation of the slurry and does not need the low moisture content of sludge. An example is the filtering of sewage sludge, electroplatings wastes after neutralization, and ceramic slip.

Membrane filter presses reduce the filtration cycle to produce a highly efficient washing and drying of the precipitate, without unloading it from the filter, to achieve a low moisture content of sludge. The process of filtration in the membrane filter press is similar to chamber. But the fundamental difference is the fact that when filling the chambers with sediment it is not unloaded immediately, and further, it is pressed under the action of fluid supplied under the membrane. The possibility for squeezing appears due to the membrane plates. The use of membranes for the mechanical squeezing of sediment can significantly reduce the time of one cycle and enhance the daily performance of the filter press.
