Analysis of the Biochemical Methane Potential (BMP) and batch reactor studies of primary sludge from a paper mill

Abstract

The pulp and paper industry faces serious problems with regard to hazardous pollutants that are generated during its manufacturing process. The dewatered primary sludge (DPS) from the paper mill production process is the largest solid by-product of that industry and considered to be harmful for human beings and the environment. Since the anaerobic digestion has been widely used as a treatment method for organic waste and for the generation of methane gas, the anaerobic digestion of DPS with digester sludge has been looked closer by Biochemical Methane Potential studies (BMP), followed by batch reactor studies carried out on a larger scale. Thereby the anaerobic digestion with methane gas production was found to be a suitable method for paper pulp sludge treatment.
