Examination of physical, chemical, and biological methods for removing contaminants from sewage.
About this course
This course examines the physical, chemical, and biological methods used to remove contaminants from sewage before it is released back into the environment. You will learn how wastewater moves through treatment plants, from initial screening to advanced purification stages. The focus is on understanding the science behind each step and how operators monitor system performance.
Work in the laboratory at the Benchlands Campus gives you hands-on experience with water quality testing and process adjustments. You will analyse samples, calculate removal rates, and practice identifying common operational issues.
