A STUDY ON MESOPHILIC ANAEROBIC DIGESTION OF WASTE ACTIVATED SLUDGE OF PHARMACEUTICAL INDUSTRY

Environmental Engineering

All the industries which use water they also generate wastewater. This wastewater is not directly discharged in natural environment. So, its necessary to treat that wastewater before disposal. During the wastewater treatment process sludge is generated. This generated sludge is another big issue cause of its disposal. There are various treatment available for sludge. From the various methods one method is anaerobic digestion of sludge. By use of this method we can treat the waste activated sludge which is generated during the wastewater treatment. The main goal of this treatment is to reduced the amount of sludge that need to be disposed. Anaerobic digestion is a technologically simple process, with a low energy requirement, used to convert organic material from a wide range of wastewater types, solid wastes into methane. A much wider application of the technology is desirable in the current endeavours towards sustainable development and renewable energy production. For study we were used mesophilic anaerobic digestion process. By this process reduced the sludge volume and generated the methane gas. This process required minimum 40 days for good results.
