Union Minister of State for Environment launched 'Nano Bubble Technology' for cleaning and purifying water of National Zoological Park, Delhi.
 

About the Nano Bubble Technology
 

1. Nanobubbles: They are 70-120 nanometers in size, 2500 times smaller than a single grain of salt. 
    
   1. Nanobubbles have a strong negative surface charge that prevents them from coalescing and
      1. It also enables them to physically separate small particles and droplets like emulsified fats, oils, and grease from water.
          
   2. Hydrophobic nature of nanobubbles combined with their surface charge enable lifting organic and inorganic materials off surfaces similar to surfactants.
