Thickener Operation - Zeroday Enterprises

26.01.2015· Thickeners are designed to operate continuously with slurry/water consistently flowing into the centerwell with thickener underflow pumping balanced to maintain a mud bed in the thickener. Key to thickener operational efficiency is the solids must be able to settle 2-4 times faster than the nominal water up flow rate. High feed solids recoveries reporting to the bottom of the thickener .
