AN OVERVIEW OF THE TREATMENT PROCESSES USED FOR PHARMACEUTICAL INDUSTRY WASTEWATERASHISH GOME AND DR. KANJAN UPADHYAY
Technological advancement in medical sciences has greatly increased the life cycle of human beings. Research in the field of medical science for curing different types of diseases has thus resulted in production of number of different pharmaceutical products. The magnitude of waste generated has also increased due to increase in production of these pharmaceuticals. Consequently, the number of pharmaceutical industries has grown up significantly in the last two decades. Every production unit generates waste in the form of solid, liquid and gas of which liquid waste is most common and often found to be toxic in nature. Production of medicines in these pharmaceutical industries involves complex processes with complex chemical reactions and mechanisms, including fermentation technology and use of different selective catalysts hence the quality of wastewater generated are toxic in nature and it is therefore difficult to treat by simple techniques. An attempt has been made in the present study to evaluate the effectiveness of different treatment processes along with the ozonation process and also to evaluate the feasibility of ozonation process in the treatment of pharmaceutical wastewater.
