Constant Pressure Filtration*Constant pressure filtration is a cake filtration that is carrried out with a constant total pressure difference across the filter; this does not imply that the pressure difference across the filter cake is constant during the period of filtration. As the cake forms so the filtrate flow rate tends to reduce, hence also known as declining rate filtration. The most common form of filtration performed in the laboratory.
