Performance Assessment of 1.20 MLD Sewage Treatment Plant

A study was carried out to evaluate the performance of Sewage Treatment Plant in Ghumarwin area and the following conclusions have been drawn. The ranges of physical, chemical and biological characteristics of waste water quality which is in the permissible limits given by waste water/sewage effluent standard as per pollution control board. The results of parameters i.e. pH, BOD, COD, TSS, Oil & Grease after the sewage treatment is under the standards limits. The standards of sewage treatment parameters pH, BOD, COD, TSS, Oil & Grease up to 5.5-9.0, 30mg/l, 250mg/l, 100mg/l and 10mg/l. The results of pH, BOD, COD, DO and SS were 7.0 to 7.5, 18.0 to 22.0 mg/l, 150.0 to 165 mg/l, 5.0 to 6.0 mg/l and 50.0 to 56.0 mg/l, which are within the permissible standard limits . In the present study, all the above parameters were compared with the limits given by Pollution Control Board and it was found that all parameters are with in the acceptable limits. Hence it is concluded that performance of Sewage Treatment Plant is good and in working condition.
