Types Of Waste Water Treatment Plant

- Aerobic & Anaerobic

Aerobic, as the title suggests, means in the presence of air (oxygen); while anaerobic means in the absence of air (oxygen). These two terms are directly related to the type of bacteria or microorganisms that are involved in the degradation of organic impurities in a given wastewater and the operating conditions of the bioreactor. Therefore, aerobic

Waste Water Treatment Plant

processes take place in the presence of air and utilize those microorganisms (also called aerobes), which use molecular/free oxygen to assimilate organic impurities i.e. convert them in to carbon dioxide, water and biomass. The anaerobic treatment processes, on other hand take place in the absence of air (and thus molecular/free oxygen) by those microorganisms (also called anaerobes) which do not require air (molecular/free oxygen) to assimilate organic impurities. 1) The final products of organic assimilation in anaerobic Waste Water Treatment Plant are methane and carbon dioxide gas and biomass.

From the summary in Table 1, it can be concluded that it is not anaerobic or aerobic Waste Water Treatment Plant, but a combination of the two types of the technologies that give an optimum 3) Configuration for those Waste Water Treatment Plant applications where the organic impurities are at a relatively higher concentration.
