Sludge Dewatering Filter Press for Waste Water Treatment

A filter press is a mechanical device that uses a special filter medium to apply a certain pressure to the object to make the liquid dialysis out. It is a commonly used solid-liquid separation equipment. It is widely used in sand and gravel production, and some common problems related to filter presses encountered in daily production are sorted out as follows for your reference. First of all, we need to determine the solid content of sewage. As the name implies, the solid content is the proportion of solids contained in sewage. In addition, we also need to determine the amount of sewage generated every day and the working hours, calculate the processing capacity required by the filter press, and then determine the volume and filtration area of the filter press, so that we can easily choose a suitable filter press. Secondly, 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%. , can be shipped directly. 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. About the filter cloth: 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 Store in a dry 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.
