Potable water treatment
Learn about the processes involved in making water safe for human consumption. This course covers the hydrological cycle, water treatment, and supply.
Without it we are dead! Water is essential, but what processes must it go through to become fit for human consumption? This free course, Potable water treatment, will guide you through the continuous cycling of water between land, open water surfaces and the sea before moving on to an overview of the water treatment and supply process.
Course learning outcomes
After studying this course, you should be able to:
Describe the operation and mechanisms of the hydrological cycle
List and describe the major physical, chemical and biological characteristics of clean fresh water, and explain their effects on aquatic organisms
Explain the mode by which potable water is produced through the processes of screening, microstraining, aeration, coagulation and flocculation, sedimentation, flotation, filtration and disinfection
Explain how the issues of nitrates, trace organics, fluoridation and plumbo-solvency can be dealt with in potable water supply
Describe the main desalination processes used to produce potable water from saline or brackish sources.
