Water Handbook - Clarification Veolia

The amount of sludge produced during clarification can be reduced by 50-90%. The approximate dry weight of solids removed per pound of dry alum and ferric sulfate are approximately 0.25 and 0.5 lb, respectively. The resulting sludge contains less chemically bound water and can be more easily dewatered.

Clean Water and Air: Clarifier Drive Torque: Selection and Clarity

2012年5月25日  Torque required to turn a rake arm would equal the resultant force of the uniform load (L*R) [R, Radius of the basin] multiplied by the moment arm (R/2). Since most circular clarifiers have two arms, the resulting equation will be T = L*R^2 (expressed in ft•lbs [foot pounds]). Loading varies with the type of waste to be handled, material ...
