Types of Activated Sludge Process - Plug Flow, Complete Mix, SBR
In CMAS, mixing of tank contents is sufficient so that ideally concentrations of mixed-liquor constituents, soluble substances (COD, BOD, NH4-N), and colloidal and suspended solids do not vary with location in aeration basin. Plug Flow involves relatively long and narrow aeration basins so that concentration of soluble substances and colloidal and suspended solids
