Pharmaceutical waste is one of the major complex and toxic industrial wastes. Pharmaceutical industry produces a wide variety of products. This industry uses both inorganic and organic as raw materials the latter being either of synthetic or of vegetable and animal origin. Antibiotics and vitamins are produced by fermentation of fairly complex nutrient solutions of organic matter and inorganic salts by fungi or bacteria. Photocatalyst system is selected as an attractive choice in organic effluent treatment due to its properties. This process has been widely investigated as a promising technology for the efficient wastewater treatment since the photocatalyst is an environmentally friendly process and has considerable advantages such as the ability to destroy pollutants without the exertion of potentially hazardous oxidants. The effect of concentration on % reduction of paracetamol using ZnO/Solar and TiO2/Solar process. For concentrations 5, 10, 15, 20, 25 and 30 ppm solutions % reduction of paracetamol using ZnO/Solar process are 78, 70, 65, 61, 54, 51 and using TiO2/solar process are 80, 73, 68, 64, 57, 54 resp. for 120-150 contact time. As per observation as the concentration of paracetamol increase, rate of reduction decrease. As per observations both the processes are economical and having same efficiency for paracetamol reduction. For TiO2/Solar Process gives more reduction of drugs than the ZnO/Solar process. There is little bit difference in reduction of paracetamol between two processes. Both the processes are effective for paracetamol reduction. As the concentration of pollutant increase the rate of reduction decreases. As per observation the maximum reduction for paracetamol drugs from synthetic wastewater is 72.5 and 69.44% at 150 min time with 10 ppm concentration of dugs for TiO2/Solar and ZnO/Solar process resp.
