Optimisation of the filtration with filter presses - MSE ...

The general goal in optimising the filtration process is to increase the throughput capacity in the filter press, to increase the filling level of the chamber filter press, to improve cake treatment, e.g. cake washing in membrane presses, and to generally increase the degree of drying in filter presses. At this point, we develop process technology problem solutions for our customers and then ...

Replaceable Diaphragm. In a typical filter press application, approximately 80% of the solids are pumped into the press in the first half of the cycle, with the remaining half considered the consolidation stage. With membrane squeeze, the cycle is shortened and the cake moisture content is reduced (see chart). The result is increased throughput and better liquid recovery. Adding membrane ...

Another common use for a filter press is as a “variable volume” filter that uses a filter plate known as a diaphragm or membrane plate. This type of plate has a flexible drain-field which when sealed around the edges forms an integral bladder or diaphragm that may be inflated to physically press additional liquid from the filter cake. This process can significantly reduce the typical ...
