OptiDewater Gravity - for efficient broke and pulp thickening

Valmet’s OptiDewater gravity thickeners guarantee highly efficient broke and pulp thickening, delivering high-capacity dewatering in a compact and cost-efficient process for a wide range of paper and board grades. The pulp is fed into one end of the rotating drum, and gravity causes the thickened pulp to drop from the wire to be discharged at the opposite end. The filtrate flows through the wire of the rotating drum, providing a large filtration area. Water sprayed from outside the drum keeps the wire clean.
