What is the cause of cloudy filter discharge?

　　Why is the filter discharge cloudy? The main function of the filter is to provide solid-liquid separation. If the separated liquid is turbid, it means the solid-liquid separation is incomplete and many solids and liquids are mixed and separated out, so when this happens, how should the user deal with it or is there any way for the user to deal with it?

　　First of all, we should consider the liquid leakage between filter plate and diaphragm plate. The main reasons are: high material pump pressure, high flow rate; insufficient oil pressure; filter cloth folds or holes in the filter cloth; filter plate and diaphragm plate sealing surface folder debris and so on.

　　Treatment is also relatively simple, pump pressure and flow rate can be readjusted according to the reasons for failure to increase oil pressure, in the filter press process, the filter cloth is often kept clean and flat. If holes are found in the filter cloth, the cloth should be replaced in time. A nylon scraper is used to clean debris between the sealing surfaces of the two plates. After the completion of each shift in the next cycle, each filter cloth should be cleaned.

　　Secondly, the open line at the stitching of the filter cloth causes the liquid to be cloudy.

　　Treatment:Remove the filter cloth and sew it again.

　　Third, improper selection of filter cloth

　　In the selection of filter cloth, should be based on some of the characteristics of the filtrate to select the appropriate filter cloth, if not properly selected, the filter cloth will soon fail, if the turbidity in this case, it usually gradually become serious, and almost all parts of the filter cloth will be a problem. Or because the holes in the selected filter cloth are too large, it is time to replace the cloth with a suitable one.

　　If not properly selected, it can easily lead to a quick failure of the filter cloth. If turbidity occurs in this case, it will gradually become serious and almost all parts of the filter cloth will have problems, or because the holes in the selected filter cloth are too large, it is time to replace the filter cloth with a suitable one.

　　Turbidity in the discharge can have a significant impact on efficiency and should be repaired promptly if turbidity in the discharge is detected. However, if the turbidity of the discharge from a diaphragm filter press is only at the beginning of the operation, then it will slowly become clearer, which is normal.
