Degradation of Ibuprofen in Wastewater by Ozonation and Catalytic Ozonation

Abstract

Pharmaceutical micropollutanst are the most ubiquitous contaminants of wastewater treatment plants .There are different categories of pharmaceutical contaminants and anti-inflammatory drugs are the most common among them. They are partially treated in WWTP and Consequently affecting the aquatic environment. Conventional methods proves to be insufficient for their treatment .these days advanced oxidation process are in pipeline for the treatment of wastewater. In our part of work we have used two advanced oxidation methods, Only ozonation and heterogeneous catalytic ozonation. Ibuprofen(NSAID) has been chosen as model compound Mn/Al2O3 is prepared in laboratory and has been used as catalyst for this work. Heterogeneous catalytic ozonation proves to be more helpful in degrading Ibuprofen, model compound than only ozonation. The future scope of this research is to develop more better catalyst and to optimize this method to take on commercial scale Key words: Ozonation, heterogeneous catalytic ozonation, Ibuprofen
