ABOUT THE COURSE: This course is for Engineers and Scientists working towards the control of pollution from municipal and industrial wastewater. Considering the expectation of the Industries for wastewater pollution control in their premises to comply With newer and more stringent laws and acts being enforced in India and globally, wastewater treatment for effluent generated from industries has become highly challenging. This course introduces the principles of biological methods to control wastewater pollution. The course will be presented in a logical manner with several numerical problems and case studies. The topics to be covered include (but not limited to): biological treatment fundamentals, wastewater characterization, bacterial growth kinetics and reactor hydraulics, aeration and sedimentation. aerobic and anaerobic suspended and attached growth biological treatment processes, sludge management, and sustainability in wastewater treatment plant design.INTENDED AUDIENCE: Undergraduate, postgraduate and Ph.D. students of Environmental Engineering, Chemical Engineering, Civil Engineering, and Environmental Chemistry
