How to choose filter cloth for plate and frame filter press?

Plate and frame filter press filter cloth specifications, model selection has always been the number one problem that plagues filter press users. Because the filter cloth filter model is suitable or not is the most core factor related to the processing effect of the filter. The filter presses of various manufacturers are basically the same in terms of working principle and workflow. Only the selection of filter cloths for filter presses is different. Except for special appointments, filter press manufacturers generally ship a certain type of filter cloth as standard. This has caused a problem, because the users of filter presses are from all walks of life, and the nature of the processed materials is also various.

The main purpose of the experiment is to determine the acidity and alkalinity of the material, the solid content, whether it is necessary to add a flocculant filter aid and select several filter cloths to test the filtration rate. The filter cloth of the filter press selected through these links is basically inseparable.

After the preliminary selection of the filter cloth model of the plate and frame filter press, the actual large-scale production verification is needed, which is to use the machine to see the actual results and replace it if it fails. It is necessary to change several filter cloths in the early stage to see the effect of use.
