In what way anaerobic sludge digestion is important in sewage treatments?
Advertisements
उत्तर
In anaerobic sludge digestion, anaerobic bacteria, digest the aerobic bacteria and the fungi in the sludge and the remaining organic matter. During this digestion, bacteria produce a mixture of gases such as methane, hydrogen sulphide and carbon dioxide. These gases (biogas) can be used as a source of energy as it is inflammable.
