PERFORMANCE EVALUATION OF EFFLUENT TREATMENT PLANT OF PHARMACEUTICAL INDUSTRY

摘要

There is an increasing trend to require more efficient use of water resources, both in urban and rural areas. The aim of the present research work was to determine the behavior of various parameters of the pharmaceutical wastewater. The company produces bulk drugs, antibiotics, pain killers, food additives, personal care products and others. It is important for the industry to develop its own wastewater treatment system before discharging the effluent in order to meet the Gujarat Pollution control Board (GPCB) standards. Reduction of pollutants in the wastewater down to permissible concentrations is necessary for the protection of ground water and the environment. In order to design an appropriate treatment system the characteristic of the wastewater generated need to be found out with reference to the following parameters; temperature, pH, total dissolved solids (TDS), Chemical oxygen demand (COD) and ammonical nitrogen. An intensive analytical programme was followed for 4 months for monitoring pharmaceutical wastewater. Samples are collected from three points; Wet well, primary clarifier (PC) and Secondary clarifier (SO and effluent out let to evaluate the performance of Effluent Treatment Plant. The pH, TDS, COD and NH_3-N removal efficiency of Effluent Treatment Plant were found 11.71%, 92.15%, 99.47% and 90.11% respectively.
