Pressure plate filter (PF)
Lasting clarification
The BHS pressure plate filter (model PF) is a fully automatic, batch-operated filter with filter elements arranged horizontally inside a pressure vessel. It is primarily used as a deep bed or precoat filter for filtering suspensions with low solids content, for adsorptive filtration processes (adsorption through filter cake) or for clarifying filtration. The pressure plate filter is also suitable for suspensions that are moderately or extremely difficult to filter.
The filter cake builds up under pressure on top of each plate. The filtrate is discharged through a hollow shaft. The filter cake can undergo further process steps such as washing, steaming, reslurrying, blowout or drying. The filter cake is then vibrated from the set of plates and discharged from the bottom of the unit.
BHS also provides complete pressure plate filter installations including fittings, instrumentation, piping, pumps, tanks, skids and control systems. The plants have a modular design for easy transport and assembly.
