In News

• Nano Bubble Technology was launched by the Union Minister of State for Forest, Environment, and Climate Change at the National Zoological Park, Delhi, offering a groundbreaking approach to water purification.

What is Nano Bubble Technology?

• Brief: It is a cutting-edge method of improving water quality by using incredibly tiny bubbles, called nanobubbles. These bubbles are so small (less than 200 nanometers in diameter) that they are invisible to the naked eye.
• Working: Unlike regular bubbles that rise to the surface and pop, nanobubbles remain suspended in the water for a long time. This allows them to interact with pollutants and break them down.
  • Nanobubbles have a strong negative charge, which helps them attract and break down impurities in the water. They can remove algae, organic waste, and even oil and grease.
  • Nanobubbles can also increase the amount of oxygen dissolved in the water.

Advantages over Traditional Methods

• Chemical-free approach to water purification, making it environmentally friendly and safe for aquatic life.
• Nanobubble technology can be more energy-efficient, reducing operational costs.
• It can be applied to various water bodies, including lakes, ponds, aquariums, and even wastewater treatment plants.

Applications beyond Water Purification

• Nanobubbles can enhance plant growth by improving oxygen delivery to roots and increasing nutrient uptake.
• There’s growing research on using nanobubbles for drug delivery, medical imaging, and even cancer treatment.
• Applications include cleaning industrial equipment, improving fermentation processes, and enhancing oil recovery.
