How to choose the filter cloth for your filter press?

In the daily industrial production of filter presses, our common question is how to choose the filter cloth suitable for our industry? How to choose filter cloth for different types of filter presses?

We select the filter cloth for the filter press based on our requirements and the properties of the filtered material, that is, the exfoliation, chemical and physical properties of the material; the dryness of the filter cake after filtration; the impact of the filtered material on a wide range, etc.

The most important thing for us is to consider the nature of the filtered object, which accounts for more than 75% of the importance of selecting the filter cloth for the filter press.

1. The peeling performance of the filter residue directly reflects the working efficiency of the filter press equipment. The surface of the filter residue is smooth and non-adhesive, and the filtrate will quickly permeate out of the filter cloth. The filtration time is short and the efficiency is high. On the contrary, the filter residue is sticky, the filtration time will be long, and the efficiency will of course be reduced accordingly. Moreover, the stronger the adhesion, the lower the efficiency. At this time we have to choose monofilament filter cloth or satin weave filter cloth.
2. Choose according to the acidity and alkalinity of the filtrate and other chemical properties. Choose the type of filter cloth that suits you according to the different acidity and alkalinity. Polyester filter cloth has strong acid resistance, and vinylon filter cloth has strong alkali resistance. Polypropylene filter cloth has both acid and alkali resistance.
3. The shape of the filter residue, whether the particles are uniform, and whether the shape is hard, to consider the wear resistance of the filter cloth. The size is uneven and there are water chestnuts, so the selection is based on the degree. The ones with the best wear resistance are strip filter cloth and economical filter cloth.
4. The temperature of the filter material also affects the filter cloth and working efficiency of the filter press. The one with high temperature resistance is polyester filter cloth.
   Again, this is our requirement. We want the efficiency of the filter press and the dryness of the filter residue. Regeneration performance of filter cloth. When choosing filter cloth, you should also pay attention to choosing filter cloth with good regeneration performance. The filter cloth with good regeneration performance can be washed directly on the filter press to reduce the number of cloth changes. The filtration efficiency of the replaced filter cloth is restored to more than 80% after simple processing (drying, washing, etc.). So depending on the specific nature.
