A study on the determination of the use of Effective Microorganisms (EM) was carried out. EM was purchased from the office of ‘Ecopro’ Auroville, Auroshilpam, Tamilnadu, India. The waste water was collected from STET Women’s College, Sundarakkottai, Mannargudi, Thiruvarur Dt. The parameters that indicate the waste water treatment process such as odour, pH, DO, BOD, COD, TDS, TS, TSS, Nitrate and Phosphate were determined before and after the treatment of wastewater, to observe the efficiency of selected process. There was an appreciable reduction in the above mentioning values. All the parameters showed an elevated level in the raw sewage but after treatment there is a steady reduction after 5, 10, 15 and 20 days of incubation. No reduction was observed in the level of DO. All the parameters were reduced to tolerable environmental standard. Thus, this study provides valuable information regarding the application of microorganisms for the successful treatment of waste water.
