The primary treatment of sewage involves
WebbSewage Treatment. Sewage treatment is a complex process that involves several stages. The first step is screening, where large objects such as plastics and rags are removed from the wastewater. The next step is primary treatment, where the wastewater is allowed to settle, and solids are removed from the bottom of the tank. WebbMethanogens are required in the anaerobic digestion step of treatment of sewage water. Anaerobic Digestion:- Anaerobic digestion is a biological process that involves the breakdown of organic matter in the absence of oxygen.- This process is carried out by a group of microorganisms known as anaerobic bacteria, which includes methanogens.-
