New Delhi, February 3
India has used nano bubble technology for water treatment only on a pilot basis so far, and its long-term effects on water quality and animal health remain to be seen, Union Minister of State for Environment, Forest, and Climate Change Kirti Vardhan Singh said in a written reply to the Lok Sabha on Saturday. Nano bubble technology, which uses microscopic bubbles to enhance water quality, has ecological benefits such as removing contaminants, increasing dissolved oxygen, reducing biofilm, and improving conditions for aquatic life, Singh said. Compared to traditional systems, nano bubbles offer better distribution and persistence in water bodies, which may lead to more uniform oxidation and disinfection.
The management of national parks and sanctuaries, including those with aquatic animals, follows Wild Life (Protection) Act, 1972 guidelines, which cover water level maintenance, aeration, and aquatic weed removal. The Central Zoo Authority has also set hygiene and health standards for captive aquatic animals under the Recognition of Zoo Rules, 2009, issuing guidelines for their upkeep, Singh added.
