1. Course Description:
The course titled Environmental Pollution Control Methods deals with the various types of
Environmental pollution problems like Water pollution, Air Pollution and Soil Pollution. Various
basic scientific facts related to the above subjects are introduced and the application of this
knowledge for devising, developing, designing methods& systems for effective control of pollution
has been emphasized.
2. Scope and Objective of the Course:
Scope:Environment is the life support system that includes air, water and land. The human
population explosion and civic developmental activities, which are concentrated only on the
economic and social patterns, slowlydegraded the quality of the environment, which is referred as
unsustainable development. Hence engineers of all disciplines are required to play a lead role in
protecting the environment from pollution. In a broader sense the course titled ‘Environmental
Engineering’ deals primarily with Environmental protection, which is essential for sustainable
development
Objectives:By the end of the course the student should be able to achieve the following objectives.
 Understanding the basic concepts regarding the water pollutants
 To learn about the physical methods of waste water treatment and their design.
 Learning about the biological methods of treatment of waste water.
 Learning about basic concepts of Air Pollution.
 Learning about the methods of control of particulate emissions.
 Learning about the Pollution control methods foe gaseous emissions.
 To study about the solid waste methods, Soil Pollution Control methods, and Noise
Pollution control methods.
