About the Course :
This course introduces students to various types of treatment techniques adopted for a public water supply system. Students will understand the role of an environmental engineer in ensuring public health and aware about the significance of water resources and the factors affecting the quality and quantity of water. They will learn how engineering approach can enhance the environmental quality by scaling up the physical and biological purification processes that exist in nature.
Expected Outcomes:
The students will
i. become aware of the various pollutants affecting water quality
ii. know about the different treatment units available in a water treatment plant and their design
procedures
