Variable volume filters

Significant improvements were made in the 1980s and early 1990s in high capacity, automated variable volume filters that incorporate automatic pressure filtration, expression, washing, and air displacement. Some of the large plate-and-frame automatic presses can operate at up to 2 MPa (ca 285 psig), with up to 100 chambers (25,26). [Pg.19]

Variable-Volume Filter Presses These membrane filter presses are covered in the section on filtration. Two designs are used for the presses (1) the typical variable-volume filter press has a normal vertical leaf design (2) other presses, such as those provided by Filtra-Systems and Larox, are designed with horizontally arranged leaves. [Pg.1744]
