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. The scale printed on the Settleometer measures how far a sample has settled. “SSV” is the abbreviation for Settled Sludge Volume. “%” shows the settled sludge volume as a percentage of the entire sample. The sample to the right has a SSV of 350 which is also 35% of the total sample volume.
