Filter element technologies

Chamber filter press

Less peripheral equipment, resulting in lower investment and OPEX costs: Chamber filter presses are reliable and robust in many different applications. The plate pack consists of uniform chamber plates with a recess of 15- 50 mm to receive the filter cake. The standard material for chamber plates is polypropylene. Possible operating pressures: 6 bar, 15 bar, and 30 bar.

Membrane filter press

Higher DS content obtained with membrane filter presses: Membrane filter plates are designed in the same way as the chamber plates described above. A flexible membrane is secured to the support body. The membrane is impermeable and compresses the cake within the chamber after the filtration process has been completed. Liquid or gas can be used as the membrane inflation medium. Inflation pressures up to 30 bar are possible, and in special cases even higher.

Plate and frame filter presses - sheet filters

Quick filter cloth change for process filtration: The chambers in this type of filter press are formed by combining polypropylene filter plates and frames. This creates chambers of 5-40 mm, depending on frame thickness. Plate and frame type filter presses are suitable for pre-coating filtration, which is used in the beverage industry for clear filtration. ANDRITZ supplies plate and frame type filter presses for operating pressures up to 6 bar.
