Description
The average lifetime of an Andrtiz filter press is over 30 years.
With Andritz filter presses, the highest dry substance (DS) content can be achieved without additional heat consumption, and even smaller particle sizes can be retained in the filter press. Andritz will provide the right filter plates, cloths, or other components to achieve the exact degree of dewatering required.
Filter element technologies:
Chamber Filter Presses
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 Presses
Higher DS content obtained with membrane filter presses: Membrane filter plates are designed in the same way as the chamber plates. 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 & Frame Filter Presses – Sheet Filters
Quick filter cloth change for process filtraton: 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.
Operating pressures up to 6 bar.
