Sludge thickener design calculations
WebbEnergy consumption with lamella separators generally uses 0.1 kWh/m 3 to achieve an output concentration of 0.1–1.5% dry algal biomass ( Uduman et al., 2010 ). Algal recycling is an interesting strategy in which recycling algae with readily settleable algae strains, such as Pediastrum sp., improved settling efficiency by 85%.

The solids content of the digested sludge varies with the type of sludge fed to the digester. Ranges have been reported (1) from 1. 5 percent to 6. 0 percent solids by weight.
Webb8. Activated Sludge Design Calculations The table below shows typical values for three design parameters sometimes used for sizing activated sludge aeration basins: volumetric loading, food to microorganism ratio (F:M), and hydraulic residence time (HRT). Note that values for volumetric loading are given in both U.S. and S.I. units.
