<b>Review on Treatment of Pharmaceutical Wastewater</b> Industrialization is necessary for economic development, but it brings with them major threat to environment. Among from all the Industries, pharmaceutical industry contributes major role to degrade environment. Pharmaceutical products are in demand and its growth is tremendously increasing. The pharma effluent is a big issue to be treated. Ammoniacal Nitrogen, Chemical Oxygen Demand, Total Suspended Solid, Total Dissolved Solid are major pollutants from pharma sector. This paper reviews some conventional treatment technologies considering Ammoniacal Nitrogen as major pollutant. Various methods like electro coagulation, reverse osmosis is compared, and sequencing batch reactor seems more effective and efficient with 90 to 95 removal in Ammoniacal Nitrogen.
