Disc filter apparatus and method for controlling a disc filter

摘要

A disc filter is provided with pressure sensors (32) arranged in the filtrate collector piping (30,31) and configured to measure the backwash pressure of a washing liquid pumped through a filtrate collector piping to the filter plates (22) in a reverse direction during a backwash zone of each rotation of the filter discs (20). The regeneration of the filter plates (22) is automatically or manually controlled or optimized based on the measured backwash pressure.
