Water Treatment: Making Water Safe for Human Consumption

The video tutorial discusses the processes involved in making water from lakes and rivers suitable for human consumption. It covers the contaminants found in natural water sources, such as dissolved oxygen, metal compounds, plastics, sewage, nitrates, and phosphates. The tutorial explains the characteristics of potable water, which should be free of solid particles and harmful microorganisms, and have a pH between 6.5 and 8.5. The process of making water potable involves filtration, sedimentation, and sterilization, with chlorine used to kill microorganisms. Carbon filters may also be used to remove unpleasant tastes or odors.
