Pharmaceutical waste water treatment using hydrogen peroxide oxidation method

Abstract

Pharmaceutical drugs are manufactured in many ways either by chemical synthesis or biological derivatives or fermented compounds. The waste water generated from pharmaceutical industry is a complex mixture of many organic compounds, solvents and inorganic salts. The wastewater is colored, turbid with high BOD, COD and contains highly toxic water pollutants. In the present study dilution technique is introduced in primary treatment followed by hydrogen peroxide oxidation in secondary treatment and finally in tertiary treatment passed through R.O process. The results suggested that the treatment method is effective and more efficient for pharmaceutical industry effluent up to 25,000mg/l COD values.
