Filter Press (Sparkler Filter Press)


Filter PressFilter press machine is a machine used in different industries for separate the liquid and solids. The filter press finds application in the pharmaceutical industry, food industry, mining and waste management. The sparkler filter press is the cost-effective way to differentiate the liquid from the solid. The zero hold up filter press machine is also known as pharmaceutical filter press due to its wide application in the pharmaceutical industry.

Process of operation:

A filter press machine is used to separate a combination of liquids and solid material. The slurry combination is fed into the filter press machine. A positive pressure is maintained inside the machine. The liquid travels in the downward direction through the moving plate. The liquid filtered through the openings on the sides of filter plates. With the increasing liquid pressure the foreign particles or solids are held by the filter media and the clear liquid is passed through a central channel which is made by the interlocking of the pressure cups towards the opening outlet. The solid material form filter cakes between the plates are processed by the wash liquors, air, vacuum and heating to obtain the final filtered product. The process of filtration continues until the cake holding capability of the unit is attained and until the rate of filtration becomes too slow due to cake resistance.

Salient Features:
  • Enclosed structure of the machine prevents the oxidation, evaporation and leakage of the materials from the machine
  • The sparkler plates are available in two sizes   
  • The horizontal filter plate prevents the dropping and cracking of cake
  • The cake holding capacity and area of filtration is upgradable
  • The machine is highly efficient and cost-effective
  • Economical and efficient dewatering
  • Trouble free operation and low cost of operation
