Thickener Torque
A little earlier I talked about the rakes of the thickener, these are long arms that extend off of the bottom of the DRIVE SHAFT As the shaft turns the rakes will sweep the entire bed of the thickener thereby applied Torque Each rake arm is higher at its far end than it is where it joins the drive shaft This is designed this way to give the bed a slope towards the centre of the thickener ....

CHAPTER 3 SLUDGE THICKENING
SLUDGE THICKENING Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 08% solids, can be thickened to a content of 4% solids, then a fivefold decrease in sludge volume is ....
