Filtration is unit operation. A filter press is a time tested & is most commonly used liquid-solid separation equipment. It is used to reduce the bulk & weight of a product to filtered by separating liquid filtrate and solid filter cake. This process is often referred to as dewatering. Given below are the steps involved in operation: Filter Press


- The process slurry is pumped at the inlet of equipment using a feed pump 
- Filtration occurs inside filter press in series of chambers designed to increase filtration area & filtration rate. 
- Filtered liquid (filtrate) passes through filter cloths and exits the machine leaving behind solids (filter cake). 
- Filter cake remains inside chambers of equipments. this cake can be washed with solvent and/or washed with compressed air as per process requirements. 
- The equipment is then opened and the filter cake is discharged by gravity as each plate is shifted.


Above operation is a batch process. Depending on the particular application, the filter press may be used to recover either the solid particulate, the liquid stream, or both. The filter press accomplishes dewatering within a series of chambers into which a process slurry is pumped using a feed pump.
