Why is aerobic degradation more important than anaerobic degradation for the treatment of large volumes of wastewaters rich in organic matter. Discuss. |
| Answer» Aerobic degradation is more important as naturally occurring aerobic and facultative microbes (bacteria fungi, Protozoa and others) in the waste water can rapidly oxidise soluble organic and nitrogeneous compounds. Mechanical addition of oxygen makes the process faster and most of the pathogenic content of the effluent is removed. | |
