Membrane Filter Press

The Membrane filter press is intended by a Swedish company (NovaTek A.B), whereas our principal has experience with filter press systems for 20 years in various fields. There was a range of membrane hydraulic presses from manual to semi-automatic to fully automated. With the newest European technology transferring the program to NovaTek Asia, our presses are engineered on maximum performance and long-life operation. The presses have application in sewage, wastewater, chemicals, and vegetable oil Industries.

After filtering the cake within the chamber, it may be further processed to get additional effects with washing and drying. A filter press is used to receive the fluid during washing. This expels the most filtrate from the cake. Washing is drained in several stages, dividing the wash filtrate by concentration and discharging the weakest portions for the primary stages of the subsequent cycle. Also, washing may be performed with several fluids. Filter press manufacturers is washed by washing liquids into the discharge line from one side. This delivers requirements for uniform washing of the full cake area. Washing is incredibly effective in applications that need maximum phase separation. Multilevel washing achieves good results with the bottom cost in washing fluid.

During the drying process, compressed gas passes through the cake within the press to decrease the cake humidity. Air is also supplied from one side of the filter press to ensure uniform drying into the filtrate discharge line. Drying is finished to scale back the moisture content within the cake to cut back subsequent heat treatment costs, ensuring the transportation conditions of dried cake or achieving maximum phase separation when cake washing is impossible.

PP plastic is the most common material used for filter press plates for Membrane Filter Press Selection and membrane filter presses. The overhanging filter cloth forms the method space for cake filtration within the filter press and is mainly answerable for solid/liquid separation. Special materials for higher temperatures up to +130°C and lower temperatures down to -10°C are available for continuous operation. It is designed with nubs or grooves on the drainage surface of the filter press plates. Automatic filter press supports the filter cloth on the one hand and allows the filtrate to empty in a defined manner. Process-technical parameters for choosing a filter plate for your application are the filter area, chamber depth or filter cake thickness, and dewatering degree. This results in the chamber or cake volume and, therefore, the filter plate type. Essential aspects of the planning depend upon the optional process steps like filter cake washing, filter cake drying, core blowing, and far more. The standards for choosing the proper filter plate specifically include:

  • Chemical resistance

  • Differential pressure resistance

  • Temperature stability

  • Filter cloth support
