Overview

COURSE OUTLINE: The course details the usual remediation techniques practiced worldwide and provides an understanding of the relevant theoretical concepts. The current course will enable a student to:

• Develop an understanding of integrated approaches to remediating contaminated sites.

• Develop the ability to screen, choose and design appropriate technologies for remediation.

ABOUT 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.
