It is a kind of mechanical equipment, which is a commonly used solid-liquid separation equipment. It was applied to chemical production in the early 18th century, and is still widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramic and environmental protection industries. It has the advantages of stable performance, convenient operation, safety and labor saving. The plate and frame filter press is the first machine used in chemical dehydration. The plate and frame filter press has the advantages of large filtration driving force, high solid content of filter cake, clear filtrate, high solid recovery rate and low consumption of conditioning drugs. It is widely used in some small sewage treatment plants.
