The filter press is a solid liquid separation device using the principle of pressure feeding. It is highly efficient, compact, dewatering device for separating solids from liquid slurries in the form of compressed cake. It has wide range of applications by several industries like Pharma, bulk drugs, distilleries, beverages & other industries.
The unfiltered liquid is fed into the filter under positive pressure, where liquid travels in downwards direction and finds its way through opening on sides of the Filter Plates. As the liquid pressure increases, the Filter media holds the foreign particles and allows only clear filtrate to pass through the central channel formed by interlocking pressure cups to the outlet. Filtration is continued until the cake holding capacity of the unit is reached or until the filtrate rate becomes too slow owing to cake resistance.
NOTE
Filtration area and cake holding capacity have been computed for standard models 8″, 14″, 18″ and 33″ Ø.
The values of “Flow-Rates” mentioned in technical specifications have been estimated for the following operating parameters:
The actual flow-rate will differ from the estimated value depending on the operating variables.
Minimum 0.1 Kg / Cm2 & maximum 10 kg/cm2
The Cartridge assembly consists of plates, perforated screens, spacers and fitter media. Interlocking spacers internally form single pipeline. The unfiltered liquid is centrally fed under pressure from bottom inlet. The liquids spread out equally on each plate fitted with filter media. Solids remain on filter media and clear. Filtrate flows through precisely made holes on sides of plates and collects in the shell, which then comes out through the outlet. In this process, solids are evenly distributed on each plate. At the end of the cycle the cake can be dried by applying compressed air or inert gas.
Stainless Steel: SS 304 / SS 316 / SS 316 L
For hot filtration application S.S. Jacket can be provided around and at the bottom of the shell, for circulation of heat transfer media viz, hot water, Steam or thermic fluids.
