WebThe rate of sludge accumulation in facultative ponds depends primarily on the suspended solids (SS) concentration in the influent sewage. The reported rate of sludge accumulation in ponds treating municipal sewage ranges from 0.05 to 0.1 m 3 /capita/year. A value of 0.07 m 3 /capita/year forms a reasonable assumption in design. WebMixed liquor is a mixture of raw or settled wastewater and activated sludge contained in an aeration basin in the activated sludge process. MLSS are used to control the wastewater treatment plant in the suspended growth process. According to Lousada-Ferreira et al. (2010), MLSS are a critical operational parameter for aerobic MBR. dviz course free downloadWebThis factsheet highlights definitions and relationships among different types of solids in wastewater and manure.
