The reason for large blocks of black sludge floating in the sedimentation tank.
12 Jan,2025
Causes: The sedimentation tank has dead corners where local accumulation of sludge occurs anaerobically, producing CH4 and CO2. Bubbles attach to the sludge particles, causing them to float, which often results in higher ammonia nitrogen in the effluent. Additionally, a too low return ratio leads to untimely sludge return, causing anaerobic conditions.
