Water Treatment: Making Water Safe for Human Consumption

This video presents a lecture on water treatment, specifically on the processes involved in making water extracted from lakes and rivers fit for human consumption. The speaker discusses the different compounds and elements that might be present in the water, both good (such as dissolved oxygen) and bad (toxic metal compounds, plastics, sewage, nitrates, and phosphates). The presentation then moves on to explain what potable water is and what it should contain, and how rainwater is extracted and treated through various steps such as filtration, sedimentation, fine filtering, and sterilization.
