Researchers from the Birla Institute of Technology and Science (BITS)-Pilani, Goa Campus and the Indian Institute of Technology (IIT) Kharagpur have developed an indigenous nanobubble technology to improve the wastewater treatment efficiency. These nanobubbles are gas bubbles that are smaller than a micron. This discovery focusses on producing nanobubbles at scale with lower energy usage, reduce operational costs and simplify maintenance.
The technology has applications in wastewater treatment, aquaculture, irrigation and waterbody rejuvenation. This method is sustainable as compared to traditional methods as initial trials have shown improved outcomes for oxygenation and decreased chemical usage. The innovation aims to reduce reliance on imported foreign systems and offer indigenous, efficient and low-cost solutions.
