The filter press is a kind of mechanical equipment used to make use of a special filter medium to exert certain pressure on the object, to make the solid in the mixture extract, and the liquid dialysis to realize the separation of solid and liquid.

And in this process, the part that must pass is filter cloth. If there is no filter cloth, the whole filtration and separation work will not work. The filter cloth is sandwiched between the plate and the cover of the frame. The gasket is sealed in the filter plate and the frame seal face. The filter surface of the supporting filter is filled with groove. All the grooves are connected to the channel of the filtrate. A filter press consists of many parallel filters. The two sides of each filter chamber prevent solid particles in the suspension. Filter cloth that allows filtration of filtrate to filter and separate.

According to the different filtering precision required by different filter objects, speed and so on, it is realized by using different filter press filter cloth and filter bag of filter press. Each filter press plate is covered with filter cloth. For the requirements of acid and alkali resistance of different filter objects, tensile strength, filtration accuracy and filtration speed, etc. First determine the material and model of the filter cloth, and then filter the cloth according to the size and shape of the filter plate.

It can be seen that the importance of filter cloth is that the pressure of filter press is not too bad.
