ANDRITZ Sidebar and Overhead Filter Presses

You can expect higher life times from ANDRITZ filter presses: The average life time of an ANDRITZ filter press has proved to be more than 30 years. In order to maintain the high quality standards, finite element method (FEM) analyses are conducted as an integral part of our quality management during the engineering phase. Due to the low mechanical wear, ANDRITZ filter presses require less maintenance, and costs for spare and wear parts can also be kept low.

ANDRITZ is proud to announce that its filter press is now designed to reach high cake dryness without lime addition. This new serie’s features are: optimized chemical and polymer injection, superior cake discharge system and improved filter cloth. 

For typical municipal wastewater, these design features allow to reach the minimum 40% cake dryness requirement. Clear benefits are ensured : reduced sludge volumes and reduces costs to landfill, simple operations and lower maintenance costs. This ANDRITZ filter press can be also fitted with advance intelligence system to improve pressure cycle and wash water consumption. 

With the ANDRITZ Intelligent filter press options, the highest possible dewatering efficiency, completely autonomous can be achieved. 

ANDRITZ 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.

ANDRITZ Membrane Filter Presses

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.
