Physico-chemical processes for wastewater treatment

By Prof. Vimal Chandra Srivastava   |   IIT Roorkee
Learners enrolled: 1296
This course is essential for Engineers, considering the expectation of the Industries for wastewater pollution control in their premises to comply with newer and more stringent laws and acts that are being enforced in India and globally. This course introduces the principles and physicochemical methods to control wastewater pollution. The course will be presented in a logical manner with several numerical problems and case studies so that the students may adequately understand the subject and apply the knowledge after their graduation in industry and higher studies. The topics to be covered include (but not limited to): Physical treatment, pre-treatment, solids removal by setting and sedimentation, aeration, filtration, centrifugation, coagulation and flocculation; Adsorption and ion-exchange; Membrane processes; Advanced Oxidation Processes.



INTENDED AUDIENCE: Undergraduate, postgraduate and Ph.D. students of Environmental Engineering, Chemical Engineering and Civil Engineering.
