Why is aerobic degradation more important then anaerobic degradation for the treatment of large volumes of wastewaters rich in organic matter. Disuss.

Text Solution

Verified by Experts

During aerobic condition, the decomposing bacteria multiply very rapidly and associate with fungal filaments to form flocs. The aerobic bacteria decompose large amount of organic wastes of waste water in the presence of oxygen produced by algae. But during anaerobic degradation, some toxic gases are produced which kill the bacteria and fungi

Why is aerobic degradation more important than anaerobic degradation for the treatment of large volumes of wastewaters rich in organic matter. Discuss.

Biogas is a mixture of methane, carbon dioxide, hydrogen and hydrogen sulphide, the major constituent being methane. Biogas is produced by anaerobic degradation of animal wastes (sometimes plant wastes) in the presence of water. Anaerobic degradation means break-down of organic matter by bacteria in the absence of oxygen. Biogas is a non-polluting, clean and low cost fuel which is very useful for rural areas where a lot of animal waste and agricultural waste are available. India has the largest cattle population in the world (240 million) and has tremendous potential for biogas production. From cattle dung alone, we can produce biogas of a magnitude of 22,500 mm' annually. Air-tight digestion/degradation of animal waste is safe as it eliminates health hazards which normally occur in case of direct use of dung due to direct exposure to faecal pathogens and parasites. What is Biogas ?

How is biogas produced ?

    Assertion :- Aerobic respiration yields more energy than anaerobic respiration. Reason:- In aerobic respiration there is complete oxidation of organic substances in presence of oxygen and release all hydrogen and CO_(2) .
