High rate thickener HR-THK

ANDRITZ Delkor (Pty) Ltd. utilizes modern engineering technologies

Thickeners are utilized in various solid/liquid separation processes in order to increase the density of a process stream. Feed solids concentration is the single most important variable affecting the sedimentation properties of given slurry.
