Taking the box filter press as an example, if 100 cubic meters of sewage is treated per hour, and the solid content rate is 8%, a filter press with a filter chamber volume of 8 cubic meters is required, and a filter press with a filtration area of 500 square meters can be selected.
What is the moisture content of filter press mud cake?
The filter press can realize the solid-liquid separation of the sludge. Generally, the moisture content of the sludge before entering the filter press is above 90%. After the filter press treatment, the moisture content of the filter cake can be reduced to 30%-60%. drop shipping. According to the different materials, before entering the filter press, add appropriate flocculant to the materials to make the solid matter aggregate together, so as to speed up the filtration speed and improve the filtration effect.
How long can the filter cloth last? Can I not change it?
The service life of the filter cloth is generally 3-6 months. In order to ensure the filtering effect and prolong the service life of the filter cloth, if the filter cloth is not used for a long time, the filter cloth should be cleaned, dried, and placed in a dry place. Store in a different place and avoid folding as much as possible. When the filter press is used frequently, if the filter cloth is found to be damaged, it should be replaced in time.
Filter cloth cleaning solution for filter press
When buying a filter press, there will be a special filter cloth cleaning system. The system can automatically flush the filter cloth with high-pressure water through valve switching. The system has single-sided flushing and double-sided flushing, and the double-sided flushing structure has brushes for better cleaning effect. There will be a cleaning device to clean the filter press during a cycle of operation to prevent filter residue from adhering to the surface of the filter cloth; if there is a working condition that is difficult to clean, it is recommended to use the traditional washing method.
Due to the different materials of the filter cloth, we need to understand the properties of the filter cloth filtrate before cleaning, so as to choose the appropriate cleaning method. When the filtrate is under acidic conditions, we should choose weak alkaline water to filter the cloth. Soak, generally soak for 10 to 24 hours, then gently rub a few times, then rinse with water, then dry before use. When the filtrate is acidic or neutral, we only need to change the soaking liquid into weak acid. In addition, it should be pointed out that when the filtrate is sticky, we need to add some corresponding diluents to the soaking liquid to achieve a better washing effect.
