Introduction

According to the development of filters, the earliest filtration was mostly gravity filtration. Later, pressure filtration was used to increase the filtration speed, and then vacuum filtration appeared. The rotary drum vacuum filter invented in the early 20th century realized the continuous operation of filtering. Since then, various types of continuous filters have appeared one after another. Filters that operate intermittently (such as plate and frame filter presses) have been developed because they can achieve automatic operation, and the filtering area is getting larger and larger. To obtain filter residues with low moisture content, mechanical press filters have been developed.
