The Abnormal Problem Of Activated Sludge System And Its Solution Come From Aquasust Plastic Manufacture --MBBR Media Supplier
Abnormal sludge properties, sludge expansion and abnormalities
The amount of suspended solids (ESS) in the effluent will greatly affect the treatment effect. Since most of the SS in the influent water has been removed by pretreatment processes such as grille, grit, and primary sedimentation, the remaining small amount of SS is absorbed by the activated sludge after entering the aeration tank and constitutes a component of the sludge. Therefore, the ESS is actually composed of bleached sludge. The amount of ESS is related to the settling and coagulation performance of the activated sludge and the operating conditions of the secondary settling tank. For a normal treatment system, ESS should be less than 30mg/L or only accounted for less than 0.5% of the activated sludge concentration, that is, when the mass concentration of sludge in the aeration tank is 2～4g/L, ESS should be 10-20mg/L. If it exceeds this limit, it means that the sludge has poor properties, which is often caused by the floating of large or small particles of sludge and the swelling of the sludge.
