Filter presses

A filter press provides sludge dewatering by pressing the sludge between a series of 20-80 porous plates, forcing water from the sludge by applying high pressures to the sludge layers. It is the only mechanical thickening or dewatering technology that is limited to batchwise (rather than continuous) operation, and can routinely achieve cake product dry solids concentrations of 35-45%.

Biosolids are usually considered to be the useful fraction of the sewage sludge. They are generally higher in solids concentration and lower in pathogen content, having gone through a stabilisation process such as chemical dosing, digestion and/or drying.
