Abstract
A vacuum disc filtering system is disclosed wherein each of the discs possesses a separate control for its vacuum, feed, drain and blow discharge. The filter discs are of one piece construction and divided into segments by means of grooved radial arms. The radial arms are adapted to receive a caulking media for holding a filter cloth on each of the segments. The filter disc is true running and any of the discs in a filter system may be operated separately and independently of the other discs.
