It is estimated that the sludge’s age in the system can reach more than 600 days. Under such a long age, the sludge produced by the system will be re-metabolized and degraded by the microorganisms after hydrolysis and reach a dynamic balance between production and digestion. Mud production is greatly reduced.
The pre-design units capacity ranges from 65 GPD (0.25m³/day) to 5.2 MGD (20,000m³/day); In addition, the equipment capacity can be expanded by 20,000 m³per unit.
The land occupied is only about 1/5 – 1/3 of the conventional technology, offering also a beneficial small footprint.
Less sludge production. Sludge production is only about 15%-20% of the conventional process sludge production.
The biochemical effect is improved while the operation control of the system is flexible and stable, obtaining a high-quality effluent. The system consists of 4 main parts: bio-selection tank, anoxic tank, aerobic tank, and a final sedimentation tank.
