Aerobic Process Principle:
Microbial reactions take place in the presence of molecular/ free oxygen, Reactions products are carbon dioxide, water and excess biomass.
Applications:
- Net Sludge Yield: Relatively high
- Waste water with low to medium organic impurities (COD < 1000 ppm) and for waste water that are difficult to biodegrade e.g. industry waste water, municipal sewage, refinery waste water etc.
- Post Treatment : Typically direct discharge or filtration
Example Technologies: Activated Sludge e.g. Extended Aeration, MBR, Fixed Film Processes e.g. Trickling Filter/Bio tower
