Water Treatment and Purification

Water (H2O) is a clear, odourless, tasteless liquid that freezes at 32°F or 0°C and boils at 212°F or 100°C. It is essential for health, food production and environmental management. This course teaches you the chemistry of water and water purification processes. We examine water’s basic properties, such as alkalinity and ‘hardness’, and lay out the fundamental principles used in its treatment.

The course breaks down each step of water purification, including neutralisation and the flotation and reduction processes. We study water’s inorganic substances and conduct a chemical analysis of major and minor ions. We explain how to control the health impacts of volatile organic compounds and synthetic organic compounds. The course then moves on to metalloids, the effects of heavy metals and the pollution control measures used to mitigate them. Finally, we explain how to implement a chemical hygiene plan and employ effective safety measures in the laboratory.

The importance of safe drinking water in promoting health cannot be overstated. Chemical contamination has been identified as one of the most significant water pollutants and poses a serious health risk. This course explains water purification processes by exploring the chemistry and treatment principles that drive them. We also identify the conditions that water must meet before it can be safely drunk. Sign up to improve your understanding of the chemistry of water and the treatment and purification process that make it safe for human consumption. These principles are crucial in civil engineering efforts to protect our most precious natural resource.
