Abstract
The investigations were carried out at the Primary Waste Water Treatment Plant in Beaconsfield, Quebec, and the plant performance and efficiency determined. The removal values of Suspended Solids and Chemical Oxygen Demand determined, compared favourably with expected. Values for primary treatment processes, found elsewhere. Results of experimental tests made at the plant showed that over 10% of solids in the primary sludge could be obtained by maintaining a sludge blanket depth in the thickener of over 3 feet. Thickening of sludge was controlled by using the concept of Sludge Volume Ratio S.V.R., defined as the volume of sludge blanket held in the thickener, divided by the volume of sludge pumped per day from the thickener.
