In this world there are many areas where pure water is not
available for people. Many people suffer with diseases because of impure water.
Science is always serve humanity with its invention. A water filter is a tool which provide us pure water.Science gives us many new
gadgets and tools by which we can purify water like filtration plants, some
plants which converts salt water into normal water etc. These plants are huge
and are for commercial use due to this require big investments and planning.
These huge water filtration plants can't be seen in poor countries because they
don't have much amount of capital.
Now, A very famous science institute NASA has invented a
water filtration bottle for providing pure and fresh water. NASA uses
Super-light material for this bottle. OKO a Swedish company utilizes this
technology and become successful in extracting water from cola drinks. This
water is pure, Odourless and ready to drink.
OKO designed these bottles in three sizes with three
different levels of filtration.OKO initially provides six colors which are
green, orange, blue, black, white and light blue.
The three levels of filtration are as follows.
Level#1: This system is carbon based and it reduces chlorine
taste from water and provide clean water.
Level#2: This filter contains 400 tiny holes and positively
charged electro-absorption process which trap harmful water impurities. This
filtration technique has been provided for space station and called it as
"State of Art in water filtration technology ".
Level#3: It is only for customize usage and also large
volume of water required for processing. This level of filtration filters only
known elements in a specified volume of water in worst environments.
