Biological treatment that decomposes organic matter in wastewater using the power of microorganisms. This explains the differences between aerobic treatment, which uses oxygen, and anaerobic treatment, which does not, as well as how they can be combined.
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.
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.
MBR, which separates sludge and water using a membrane instead of a settling tank. This explains the role of the membrane and the perspective on membrane fouling that cannot be avoided during operation, as well as the considerations for cleaning.
Convert ammonia into nitric acid and release it as nitrogen gas from water. Why is the denitrification tank placed before the nitrification tank? Explain the conditions and combinations of the two reactions.
