Conventional anaerobic and aerobic treatment techniques are competent enough to partially reduce the COD and BOD in PPME. The anaerobic digestion and activated sludge process have also been used for treating PPME (Catalkaya & Kargi, 2008). The combinations of biological and physico-chemical methods were also done to find out the practical feasibility. Nakamura et al. (1997) were able to treat Kraft paper effluent to some extent using a combination of activated sludge process and ozonation, while Chandra et al. (2009) carried out aerobic treatment enclosed with activated sludge processes, aerated lagoons and biological reactors have also been used for bioremediation of paper mill effluent. The microorganisms reported for aerobic treatment were belonging to Pseudomonas putida, Citrobacter sp. and Enterobacter sp.
