- The Settleometer shows the solids liquid separation capability in the secondary clarifier. Sludge must separate from the liquid for settling to occur. Settling of sludge in the clarifier is a critical part of the activated sludge process. Poorly settling sludge is a strong indication of process problems and solids loss in final effluent.www.ravenep.com/Settleometer-p/c-10102.htm
