The activated sludge process is used to treat waste streams that are high in organics. The species of microorganism that dominates a system depends on aerobic heterotrophs because the process is strictly aerobic with few exceptions. Aerobic heterotrophic bacteria are main activated organisms. Heterotrophic bacteria obtain energy from carbonaceous organic matter in influent waste water for the synthesis of new cells.
