Current Context : The Union Minister of State for Forest, Environment, and Climate Change recently launched Nanobubble technology, at Delhi’s National Zoological Park, enhances water cleaning and purification, promoting aquatic health.

What are Nanobubbles?

• Tiny bubbles, 70-120 nanometers in size, 2500x smaller than a salt grain.
• Made from any gas and injected into liquids.
• Possess unique physical and chemical properties superior to traditional aeration methods.

Properties:

• High Surface Area: Enhances gas transfer efficiency.
• Brownian Motion: Nanobubbles remain suspended in water, distributing oxygen evenly.
• High Oxygen Transfer: Achieves up to 90% oxygen transfer efficiency.
• Surface Charge: Negatively charged, improving pollutant separation.

Applications:

• Water treatment (removing contaminants).
• Agriculture and aquaculture (improved growth and health).
• Industrial use (oil and gas recovery, cleaning surfaces).
