Ravi Kumar Chhetri

Ravi Kumar Chhetri is a Senior Researcher in the Department of Environmental and Resource Engineering at the Technical University of Denmark (DTU), where he contributes to the Water Technology & Processes group and the DTU Microbes Initiative. His research is closely aligned with UN Sustainable Development Goals, particularly those related to clean water and sanitation.

His research interests focus on advanced water and wastewater treatment technologies, including chemical disinfection (ozone, hydrogen peroxide, peracetic acid), biofilm-based systems, UV-LED disinfection, and treatment train approaches for complex pollutants like PFAS and antibiotic-resistant bacteria. His work bridges chemical engineering principles with environmental applications.

The recent publication trends indicate a strong emphasis on offshore produced water treatment, biofilm reactors, and innovative disinfection methods. His research combines experimental validation with practical implementation, particularly in challenging environments such as seabed reactors and combined sewer overflows.

• Contributor to UN Sustainable Development Goals (Clean Water & Sanitation)

He has been involved in advising and collaborative research, particularly within PhD projects such as his own on CSO disinfection, and has contributed to major research initiatives including FUPARU and DesiCSO. His work often involves interdisciplinary collaboration with environmental chemists, engineers, and public health experts.

Dr. Chhetri is actively engaged in research dissemination, having presented at multiple conferences on topics such as biological treatment of produced water and disinfection of antibiotic-resistant bacteria. His laboratory and field work support sustainable water infrastructure development.
