S Monica, L Karthik, S Mythili and A Sathiavelu

The present study was conducted for sewage treatment using effective microbial consortium. The Effective Microorganisms (EM) like Lactobacillus, Pseudomonas, Aspergillus, Saccharomyces and Streptomyces were isolated from respective sources. The microbial consortium was formulated using molasses as medium at pH 3.8 and incubated at 37°C for 3 days. The sewage treatment was carried out with the addition of 3 ml/l EM solution under aerobic condition. The BOD, COD, TDS and TSS were reduced by 85%, 82%, 55%, and 91% respectively after 3 days of treatment. The results showed that the formulated EM was efficient for sewage treatment and thereby it reduced the environmental impact.
