Technical info
Activated sludge settling issues are common in wastewater treatment systems. Problems such as fine sludge, slow settling, and difficulty in settling often occur...
Current status of the treatment system: Wastewater from residential buildings, high-rise buildings. System capacity: 100 m³/day. Aerobic tank: 60 m³. Nitrogen levels: 1.5 times higher than the discharge standards.
The drainage system at the production facility is clogged, leading to slow drainage and an increasing occurrence of unpleasant odors.
The drainage system of the sink in the kitchen and the food preparation sink is draining very slowly, causing water to back up and overflow outside the sink rim.
The system does not meet the QCVN 40:2011/BTNMT standards for industrial wastewater. The wastewater has a slight sour odor, and the treated water quality is not as good as initially. The indicators for BOD, COD, TSS, and total nitrogen exceed the standards.
