Early 20th century invention of rotary drum vacuum filter for filtering operations continuous. Since then, various types of filters have appeared in a row. Batch filter (for example, plate-and-frame filter press) was developed for its automated operation, filter area is growing. To get the moisture content low residue, filter has been developed for mechanical press.
