ABSTRACT
Once the wastewaters have been collected and their characteristics have been determined, the wastewater treatment processes can be evaluated and the best process can be proposed. Treating domestic wastewater and industrial process wastewater has been the primary focus for industries to date. Anaerobic wastewater treatment requires a complex consortium of bacteria working together to bring about maximum stabilization of the organic contaminants in the wastewater. Treatment of domestic wastewater utilizes physical and biological systems. The most efficient bacteria grow under the specific environmental conditions imposed by the wastewater characteristics and tank configurations. In dispersed growth systems the separated microbial solids can be returned back to the aerobic bioreactor to increase the total population of available microbes for rapid metabolism of the biodegradable organics in the wastewater. The bacteria tend to metabolize the soluble organic compounds in the wastewaters to carbon dioxide, water, ammonia, and new cells.
