Activated Sludge Process Workshop Manual
by Ontario Ministry of the Environment
⇥ Biological oxidation reactions in the aeration basin, because of their dependence on microorganism quantity and activity, will proceed more efficiently when the mixed liquor pH range is held within 6.5 to 8.5. Aeration pH above or below these values will cause death to a number of microorganisms and result in a reduced process efficiency.🏁
