ABSTRACT:
An improved anaerobic waste water treatment process comprising the steps of introducing waste water containing organic material into a first reaction zone containing thermophilic, fixed growth, hydrolytic and acidogenic bacteria and fermenting the waste water in the first reaction zone under anaerobic conditions at a pH of between about 5 and 6 and a temperature between about 115 to 160 degrees Fahrenheit to produce an acid effluent. The acid effluent is then conveyed to a second reaction zone containing thermophilic, fixed growth, methanogenic bacteria where it is fermented under anaerobic conditions at a pH between about 7.2 and 8.2 and at a temperature between about 115 to 160 degrees Fahrenheit to produce process effluent and gas including methane. The methane is collected and the process effluent is removed.
