Abstract

The aim of this research work was to assess the feasibility of ozone based treatment method for the removal of key pollutants, such as COD, TSS, conductivity and colour, from the wastewater generated during the operations of a pharmaceutical plant. This investigation evaluated the effectiveness of ozone treatment at varied process parameters like pH, ozone exposure timings and ozone doses in order to find optimized conditions for maximum elimination of water pollutants. The study concluded that adequate results were achieved at higher pH values (10-11), extended ozonation exposures (60-90 min) and maximum ozone concentrations (400-500 ppm). This study suggested that ozonation was an efficient method for the treatment of wastewater from pharmaceutical industry. Since all the experiments were conducted at ambient temperature without using any heat or additional chemicals and thus this method proved to be an environmental friendly technique to reduce pollution load in pharmaceutical wastewaters.
