IIT Guwahati researchers develop sustainable method for Ammonium removal from wastewater
microalgae and bacteria.
This approach not only offers a sustainable solution but also drastically cuts down on energy consumption compared to traditional wastewater treatment methods.
The research, supported by the Department of Science & Technology – Fund for Improvement of S&T Infrastructure (DST-FIST) program, has been published in the prestigious Chemical Engineering Journal.
The paper was co-authored by Prof. Kannan Pakshirajan from the Department of Bioscience and Bioengineering, and Prof. G. Pugazhenthi from the Department of Chemical Engineering, alongside post-doctoral and research scholars Dr. Arun Sakthivel, Dr. Surjith Ramasamy, and Sumeet Kheria at IIT Guwahati.
Ammonium in wastewater, derived from sources like domestic sewage, industrial waste, agricultural runoff, and landfills, poses serious environmental risks. It can lead to harmful algal blooms, increased water acidity, and oxygen depletion in aquatic ecosystems. Traditional ammonium removal methods involve oxygenation, which accounts for up to 90% of a treatment plant's energy consumption.
