<p>An activated-sludge process for wastewater treatment comprising the steps of: (1) feeding raw wastewater to an aeration tank containing activated sludge; (2) supplying air into the aeration tank to produce aerobic and anaerobic areas in said tank; (3) separating sludge from the mixed liquor coming out of the aeration tank and concentrating at least part of the separated sludge or said mixed liquor in a concentrator to thereby produce concentrated sludge and separated water; and (4) feeding the concentrated sludge into the aeration tank and maintaining the MLSS concentration in said tank at a value between 7,000 to 15,000 mg/liter, thereby removing the organic matter and nitrogen components from the wastewater within said aeration tank.</p> |
