In the sedimentation tank, the sludge does not settle and overflows along with the supernatant... Its true nature might be filamentous bacteria that have proliferated excessively within the sludge?
Why doesn't the sludge settle despite the low presence of filamentous fungi? This explains how to identify "viscous bulking," which is characterized by stickiness and lack of compaction, and discusses the drainage issues that can easily arise.
The starting point of various methods of the activated sludge process, the standard activated sludge method. We will compare what the modified methods have changed and the differences in retention time and load.
When the moisture content decreases by 1 point, how much does the amount of dewatered sludge change? This will explain the calculation method, the type of dewatering machine, and what happens to the dewatered sludge afterward.
The activated sludge method cultivates a mass of microorganisms to decompose organic matter in wastewater. This explains the roles of the aeration tank and the sedimentation tank, the reasons for recycling sludge, and the key points for daily management.
How many kg of sludge is contained in 1 cubic meter of the aeration tank? I will explain the meanings of MLSS and MLVSS, as well as concentration management using SV30 and SVI.
