Actual sludge production in municipal secondary wastewater treatment plants
Abstract This study presents actual sludge production data from26 activated sludge treatment plants which were evaluated in an attempt to provide a better basis for design of sludge facilities. The plants studied received normal pollutant loadings and showed good performance. Actual sludge production rates obtained, varied according to plant size and were different from those typically used in design. The mass of waste activated sludge solids, produced per mass of biochemical oxygen demand (BOD) removed, increased with organic loading applied and a linear correlation was found. Values obtained were higher than cell yield coefficients based on process kinetics. The results suggest that empirical sludge production coefficients developed in well-performing plants could provide a more realistic design basis.
