A small bubble with Great potential
You must have heard about micro-bubble in
various places. Micro-bubble is basically an ultra-fine bubble, the diameter of
which will be in terms of micrometers (About 50 microns). The size of human
hair is about 70 microns and hence you can imagine how small a micro-bubble is.
Why Micro-bubble has attracted so
much ?
Micro-bubbles are very small bubbles than
the normal foam, now it is discovered that, these small bubbles have some special
property which the large size bubbles doesn’t have. Now people have thought to
take advantage of special properties of these micro-bubble which will be used
in daily activities.
Following are various merits of Micro-bubble.
Extremely slow surface rising speed:
Since the volume of the micro-bubble is
small compared to normal bubble, its buoyancy is also less, so it reaches the surface
very slowly. Hence it levitates in water for long time.
Easily soluble in water:
Micro-bubbles
are so small that the distance between the centres of the neighbouring bubbles
is very less. So they are very easily soluble in water compare to normal
bubbles.
Easily get absorbed by the under
water substance:
Since micro-bubbles
are negatively charged, they get easily absorbed by the positively charged under
water substances.
Bubbles are not easily breakable:
Since the
micro-bubbles are negatively charged, coalescence and absorption between the bubbles
is less likely to occur. While marinating their small size,
they get dispersed uniformly in the liquid.
Micro-bubbles are used in various
fields such as:
Waste water treatment: If the micro-bubble is generated
at the bottom of the tank which contains populated water, then these bubbles
get absorbed into the dirt particles and make them float on the surface of the
tank, which can be easily removed to get the dirt free water.
This
process is generally called pressure floatation process (Dissolved Air Flotation).
Washing: The thing which has to be washed
is kept in the water tank and the micro-bubbles are generated.
These negatively
charged micro-bubbles will reach the detail parts of the thing and get absorbed
by the dirt particles and make them float on the surface. The dirt particles which
are on the surface can be easily removed.
Personal Usages: Micro-bubbles water is used in
bath tub and for washing scalp. If micro-bubble is generated in high density an
anion will be generated. Moreover, a comfortable stimulus is given to skin with
the shock wave which comes out at the time of disappearance of a bubble.
Farming: Micro-bubble water will play an
active part in culture of an oyster and the hydroponics of a strawberry. Since
the oxygen rich water is supplied directly to the plants growth will be
remarkable increased.
