In line with a press launch, the brand new technique is not going to solely supply a sustainable answer but in addition drastically reduce down on power consumption in comparison with conventional wastewater remedy strategies.
The discharge added that the analysis led by Prof. Kannan Pakshirajan was supported by the Division of Science and Know-how – Fund for Enchancment of S&T Infrastructure (DST-FIST) program. It has been printed within the Chemical Engineering Journal.

Moreover, the paper was co-authored by Prof. Pakshirajan and Prof. G. Pugazhenthi from the Division of Chemical Engineering, alongside post-doctoral and analysis students Dr. Arun Sakthivel, Dr. Surjith Ramasamy, and Sumeet Kheria at IIT Guwahati.
As a part of the analysis, the staff had designed a photo-sequencing batch reactor (PSBR), the place microalgae produce oxygen throughout photosynthesis, which is then utilized by nitrifying micro organism to transform ammonium into nitrate, adopted by denitrification underneath anoxic circumstances utilizing denitrifying micro organism to kind nitrogen as the top product.

The method eliminates the necessity for exterior oxygen aeration, thereby making it extra energy-efficient.
Prof. Pakshirajan, who represents the Division of Bioscience and Bioengineering at IIT Guwahati, stated the brand new system provides a sustainable answer for treating wastewater ‘whereas reducing down on power prices.

“By harnessing the oxygen naturally produced by microalgae, we can make the process not only more efficient but also highly cost-effective,” Prof Pakshirajan added.
