How To Clean The Filter Cloth Of The Filter Press

If you use a traditional plate and frame filter press in the sludge dewatering process, you should often face the problem of cleaning the filter cloth. How to quickly clean the filter cloth of the plate and frame filter press, improve efficiency, shorten time, and increase efficiency and reduce energy for sludge treatment enterprises has become a concern. As follows, the filter press manufacturer Zhengzhou Yingxin summarizes it.

    According to the material used in the filter cloth of the plate and frame filter press, long-term use of the filter cloth will cause clogging of the filter cloth, which is related to the hole diameter and interface of the filter cloth, but most often, it cannot be effective. The cleaning caused by the accumulation of the mixture may affect the filtering effect of the filter press equipment and reduce the efficiency of sludge dewatering. Therefore, it is best to clean the filter cloth regularly. The filter cloth of the filter press can be cleaned in the following ways:

    1. For the filter cloth used for alkaline filter media, it needs to be soaked with weak acid solution when cleaning;

    2. For the filter cloth used for acidic filter media, it needs to be soaked with weak lye when cleaning. Before cleaning, the filter cloth can be soaked for 1 to 2 days. Then clean.

    In addition to manual cleaning, there are several ways to clean:

1. High pressure water cleaning;

     2. Cleaning by washing machine and adding cleaning agent;

     3. Use hydrochloric acid or citric acid to clean;

     4. Caustic soda or hydrogen peroxide cleaning;

     5. The washing cycle is determined according to the actual situation, generally not more than 2 months.

     The cleaning cycle of the filter cloth of the plate and frame filter press depends on the sludge dewatering capacity, the quality of the sludge, the material of the filter cloth, etc. There is no fixed limit.

     Of course, the ultra-high pressure automatic sludge filter press launched by Zhengzhou Yingxin at this stage does not need to clean the filter cloth. *The main reason is that the ultra-high pressure sludge filter press thoroughly dewaters the sludge and produces low-moisture sludge. The cake is non-sticky and does not stick to the filter cloth, so the clogging of the filter cloth rarely affects the efficiency of sludge dewatering. If the sludge treatment equipment needs to be upgraded or updated, the Zhengzhou Yingxin ultra-high pressure automatic sludge filter press can be selected first, which not only reduces manual operations, but also greatly improves the efficiency of sludge treatment.
