Plate and frame filter press is an intermittent solid-liquid separation equipment, which is composed of filter plates and filter frames arranged to form filter chambers. Under the pressure of the feeding pump, the feed liquid is sent into each filter chamber, and the solid and liquid are separated through the filtering medium. Widely used for wastewater treatment in various industries such as chemical, dye, petroleum, ceramics, pharmaceuticals, sugar, food, starch, maltose, paint, metallurgy, etc. It has the advantages of good separation effect, wide applicability, simple operation, and low investment, especially for the separation of viscous fine materials, which has incomparable superiority.
The structure of the plate and frame filter press is relatively simple, easy to operate, stable, flexible in the selection range of filtration area, occupies less space per unit filtration area, has a large filtration driving force, and the resulting filter cake has a low moisture content. It has strong adaptability to materials and is suitable for various types of sludge.
