Press filter cloth description

Press filter cloth has always been a crucial component in the press filters. It’s quality and correct selection decides the throughput and filtration performance. Nowadays 98% of the press filtration equipment using filter cloth as the filter medium. The press filter cloth has obvious widely range applicability and serviceability.

The press filter cloth also has diverse weaving type to obtain different particle retain and filter cake discharge capacity.

For instance, press filter cloth in twill weave has more smooth surface than plain weave for easy cake release and larger aperture for dewatering and anti-blinding. It’s suitable for high viscosity slurry.

Press filter cloth
There are three types of the vertical filter press – Chamber press filter, Plate & frame press filter, and Membrane press filter. Even though the press filter cloth for the three above are all quadrate, they are different.

2) Select the fiber: There are monofilament, multifilament, short fiber, etc. of filter press cloth for press filters, the fiber influence the filtration performance, strength, regeneration, and other properties.
3) Choosing the right weave pattern
The weave pattern affects the precise, cake discharge and cloth regeneration performance.
4) Cloth after-treatment, heat set treatment
5) Filtration experiment on the raw materials slurry is important after the preliminary selection of the filter press cloth. A sample experiment was carried out on the material filtration to check the filtration rate, retention performance, filter cake moisture content, cake release performance, regeneration properties, etc.
