How to Choose the Right Sludge Dewatering Equipment?
17.12.2021 Chamber filter presses The key advantage of chamber filter-presses is the ability to obtain a filter cake of significantly lower moisture content than through other types of dewatering equipment – up to 65-70%. The use of chamber filter presses is most effective in cases where the incineration of the filter cake is expected.

Filter Press Sludge dewatering - LiqTech Water
The filter press then dewaters the sludge and delivers filter cakes of up to 80 % dry matter, depending on the pressure and application. The liquid will permeate the filter press filters, called filter cloths, attached to the filter plates, while solid will be retained. This will make the solid build up as thick layers on the filter press filters. The thicker the solid layer gets, the better ...

Filter cake washing for filter presses - MSE Filterpressen®
Filter cake washing is an optional processing step in the filter cake post-treatment in combination with the membrane technology. This involves a chemical/physical treatment of the filter cake or replacement of the filtrate still contained in the filter cake with a washing medium. The dewatering properties of the suspension determine the required filtration or washing

The cake dewatering process in a filter press is quite complex and can include a series of steps, such as consolidation by membrane squeezing, desaturation by air blowing, and deliquoring. Each step should be optimised and properly set-up (Stickland et al. 2016, 2017). This versatility makes the filter press design and sizing phase critical. In fact, the technology and all the
