TEAM Process

Bi-phasic reactor– Acidification

The organics from solid waste are extracted in the form of leachate (liquid form) by the action of hydrolytic and acidogenic microbes

digested slurry is rich in available nutrients which is dried and used as manure

– Methanation The extracted organics (leachate) are treated in a

high rate upflow anaerobic sludge blanket reactor to form biogas (composed of methane and carbon dioxide) by the action of acetogens and methanogens

Schematic diagram of TEAM

Salient features of TEAM process

• Acidification– 6 reactors for extraction of organics– Volatile fatty acids – HRT of 6 days– Digested waste is a very good manure

• Methanation– High rate methanation reactor- UASB– HRT-16 h and COD reduction- 90%– Treatment of high strength leachate to produce

biogas (70-75% Methane)
