Abstract

The objective of the final year project is to provide an alternative for treating pharmaceutical wastewater using solar photocatalytic treatment. It has been demonstrated that the solar photocatalytic method can be an alternative to conventional methods of waste treatment which are much more complex and costly. The fact that the semiconductor can be activated by sunlight greatly reduces the use of electric power and hence the operating cost and time. Furthermore, the catalyst has the potential for reuse and the catalyst use is safe and nontoxic. There were two batches of sample taken from a pharmaceutical industry with initial chemical oxygen demand (COD) of 446 and· 2052 mg/L. In the experiment, various dosage of zinc oxide was used, from !giL to 5g/L. The use of3g/L zinc oxide resulted in around 70% and 24% of COD reduction when exposed to sunlight (0.75-0.1 kW/m2 ) for 150 minutes, respectively. However, the results achieved was not as expected and did not meet the requirement the Malaysian discharge standard A and B. Several alternatives and improvements are listed to improve and achieve the objective of the project.
