Sludge residence time
Webb23 apr. 2024 · Considering aeration tank, secondary sedimentation tank and reflow sludge pump house as a whole, in order to minimize the cost and total operating cost, the sludge reflow ratio is usually limited to within 150%. For general urban sewage, the reflow sludge concentration in the secondary sedimentation tank is usually 4-8kg/m3. WebbThe retention time is normally long (up to 4-6 hr), and is chiefly devoted to settling. Rapid mix is typically designed for 3-5 min and slow mix for 15-30 min. This design affords great flexibility in establishing proper chemical addition points. Also, such units are relatively insensitive to sudden changes in water throughput.
