Discussion on the causes of turbidity in the effluent of plate and frame filter press

Plate and frame filter press is widely used in chemical, metallurgy, printing and dyeing, food, pharmaceutical and other industries Its main purpose is to carry out waste liquid treatment, solid-liquid separation and recycling in the production process of raw materials The plate and frame filter press is very convenient to use, but many customers will encounter many problems in the use process, the more common is the turbidity of the discharge Therefore, there are four reasons for the turbidity of discharge in the use of plate and frame filter press: 1 The filter cloth of plate and frame filter press is damaged In this case, * the reason may be that the filter cloth is damaged You can carefully check the turbidity of the filtrate If it is caused by the turbidity of the filtrate of some water nozzles, you can basically judge the damage of the filter cloth here At this time, you need to check and analyze the reasons for the damage of the filter cloth If it is caused by the improper use of the plate and frame filter press During the subsequent operation, the correct operation method shall be taken and the filter cloth shall be replaced 2 Improper selection of filter cloth When selecting the filter cloth, the plate and frame filter press should select the appropriate filter cloth according to some characteristics of its filtrate If the plate and frame filter press is not properly selected, it is easy to cause the filter cloth to fail soon Moreover, if there is turbidity in this case, it will become more and more serious, and almost all parts of the filter cloth will have problems Or it is caused by too large opening of the selected filter cloth At this time, it is necessary to replace the appropriate filter cloth 3 The feed inlet is not well protected It is the turbidity caused by the leakage of the plate and frame filter press at the feed inlet If it is found that the problem is caused by the inadequate protection of the feed inlet, the flange, gasket and connection of the feed inlet shall be checked in time In case of any abnormal condition such as damage, the relevant parts shall be replaced in time, cleaned up, then the sealing gasket shall be densified and the feed inlet shall be tightened, and then the turbidity of filtrate shall be checked to see if it is improved 4 The suture of the filter cloth of the plate and frame filter press is opened If the problem caused by the opening of the suture of the filter cloth is found, the filter cloth shall be removed and sutured again The selection of the filter cloth of the plate and frame filter press must meet the technical requirements of filtration of the filtrate The new filter cloth should be shrunk before installation The diameter of the opening should be smaller than the hole diameter of the filter plate When matching the filter plate, the holes should be relatively concentric with the holes of the plate The feeding hole of the plate and frame filter press should be placed close to the wall of the cylinder Otherwise, the filtration will be unclear, the filtration rate will be low, the cylinder will be broken, and the expected filtration purpose will not be achieved 。 The discharge turbidity has a great influence on the working efficiency of the plate and frame filter press If the plate and frame filter press is only turbid at the beginning of its operation, then it will gradually become clear, which is a normal phenomenon More contents can be viewed: Guangzhou LVYE environmental protection equipment Co., Ltd
