The Microbiology of Anaerobic Digesters

open access: yes, 2003
The organic content of sludges and soluble wastes can be reduced by controlled bacterial activity. If the bacterial activity is anaerobic, the reduction in organic contentis achieved through sludge digestion. If the bacterial activity is aerobic, the reduction in organic content is achieved through sludge stabilization.Anaerobic digesters having ...
