I completed an internship in a drug manufacturing factory, where I gained hands-on experience in various aspects of water treatment and quality control. I learned how to operate and maintain the boiler system that converts water into dry vapour for sterilization purposes. I also trained in reverse osmosis and cooling tower technologies that ensure the purity and safety of the water supply. Additionally, I acquired knowledge and skills in emergency safety precautions and solutions, as well as the primary and secondary sewage treatment processes that remove physical and biological contaminants from wastewater. Furthermore, I learned about the safety of drug concentration contaminants and how to protect the drug production area from external contamination.
