The method to solve the problem of permeability of diaphragm filter press

First, the processing method. The filter cloth is woven through the tight processing method, which gives the filter cloth a certain structure. When the filter cloth penetrates deep into the solid particles, it is not easy to discharge. Once these particles accumulate more and more, the filter The filter pore size of the cloth will be blocked, and the filtration speed of the filter cloth will naturally gradually decrease, which will eventually reduce the working efficiency of the equipment.

2. Frequent cleaning is required to ensure the normal working efficiency of the diaphragm filter press. Although the diaphragm filter press itself has the function of removing the filter cake in a weekly cycle, the filter cloth is in contact with the filtrate for a long time. , and their working environment is under strong pressure, so there will be a situation where solids adhere to the filter cloth. If it is not cleaned frequently, the frequency of filter cloth replacement will increase.

3. When understanding the properties of cleaning, you must also know the relevant properties of the filtrate. When the filtrate is alkaline, you can choose weakly alkaline water for soaking, soak for about 24 hours, and then gently rub a few times and dry it. Just do it.
