Abstract
A sedimentation or other dewatering process conducted on a suspension is controlled by filling a body (1) that is open at its top end (2) with the suspension, establishing quiescent conditions and allowing the suspension to settle to form a supernatant layer at the top end (2), generating light from an assembly (14) and measuring the amount of scattered light (19) from the supernatant layer by a collector (21) and utilizing the measured amount of scattered light to control the dewatering.
