A Compact A2O MBR System for Water Reclamation in the Northwestern China
Based on the successful adoption of A2O MBR system with 2.5 times treatment capacity (5000 m3/d) rather than conventional activated sludge (CAS) process (2000 m3/d), A domestic wastewater treatment plant in the northwestern China was greatly upgraded that can effectively meet the requirements of wastewater treatment and reclamation. In the A2O process with high depth aeration, high organic and ammonia nitrogen removals were achieved simultaneously in a wide range of sludge retention time (SRT). This system could be also strategically controlled to achieve high phosphorous removal by optimized discharge of excess sludge. This project provided the first case study of A2O MBR system in the cold region and showed the advantages of membrane technology for water reclamation in water-deficient areas of China.
