Key Difference – Aerobic vs Anaerobic Wastewater Treatment
Proper wastewater treatment is an important requirement to prevent waterborne diseases and maintain a healthy environment for organisms. A treatment process which involves microbes or living organisms is named as biological wastewater treatment. There are two types of biological waste water treatments namely aerobic wastewater treatment and anaerobic waste water treatment. Aerobic wastewater treatment is carried out by aerobic microorganisms. Aerobic microorganisms require oxygen; hence, oxygen is supplied for aerobic wastewater treatment tanks. Anaerobic wastewater treatment is carried out by anaerobic microorganisms. Thus, anaerobic wastewater treatment process occurs without an oxygen supply. The key difference between aerobic and anaerobic wastewater treatment is that in aerobic wastewater treatment, treatment tanks are constantly supplied with oxygen while, in anaerobic wastewater treatment, gaseous oxygen is prevented from entering into the system.
