The course details the usual remediation techniques practiced worldwide and provide an understanding of the relevant theoretical concepts. The current course will enable a student to:
• Develop understanding of integrated approaches to remediating contaminated sites.
• Develop the ability to screen, choose and design appropriate technologies for remediation.

INTENDED AUDIENCE:
Environmental engineering professionals and students pursuing a degree with emphasis in Environmental engineering.

CORE/ELECTIVE: Elective

UG/PG: UG (Honors), PG

PREREQUISITES: Entry level chemistry course, and understanding of chemical, physical and biological processes on Environmental Engineering

INDUSTRY SUPPORT: CPCB, SPCB, Degremont, ERM, Ramky Enviro Engineers, Veolia Water, SFC Environmental Technologies Pvt. Ltd., Nalco Water, VA Tech Wabag, Thermax

1999 students have enrolled already!!

ABOUT THE INSTRUCTOR:




Dr. Bhanu Prakash Vellanki, is an Assistant Professor at IIT Roorkee. He holds a PhD in Civil Engineering with a specialization in Environmental Engineering from Texas A&M University. During the course of his doctoral work, Dr. Vellanki developed a new class of treatment processes, called the Advanced Reduction Processes. His research interests include Advanced Redox Processes, industrial/hazardous waste treatment, and emerging contaminants.
