Welcome to our Research Group

Our research aims at two different important emerging areas: Electrochemical techniques, and high voltage non-thermal plasma (NTP) discharge (Advanced Oxidation Technology). It includes fundamental research in the area of electrochemical, and NTP techniques. Key topics are:

• Design, and develop of sustainable electrochemical, and high voltage non thermal plasma (NTP) reactors: Scale up to pilot scale reactors
• Develop of low-cost electrode materials with higher performance efficiency
• Energy recovery from waste/wastewater
• Toxicity analysis
• Life Cycle Assessment (LCA), and Circular Economy (CE)
• Environmental Impact Assessment (EIA)
• Treatment of: Industrial-, municipal- wastewater, drinking water
• Special focus on: Contaminants of emerging concern (CEC): per-poly fluorinated alkyl substances, emerging contaminants

I am looking for hardworking, researchers to work in electrochemical, and high voltage NTP research fields, which are the research fields on global demand for water, wastewater treatment. If you are interested to work with me, feel free to write to me: nippatlapalli@iitdh.ac.in
