A portable water purifier for drinking sea water!

We have always studied since school days that 70% of the earth is covered with water but most of it is not drinkable due to sea’s salinity and minerals. Its been man’s desire to always be able to harness this seemingly limitless source of water for drinking purposes. We have made significant progress with that but never had a portable device ever.

This is one product that would have really come handy to Robinson Crusoe or Tom Hanks in the Adventure Drama named Cast Away or the most recent Thriller ‘Life of Pi’. Being able to drink sea-water is like a dream come true for every sea traveler and mariner. There are some large devices which have been developed for this purpose and converts sea water into drinkable state. But none of them are portable and not fit for storing in your bag. Designers Younsun Kim, Kangkyung Lee, Byungsoo Kim and Minji Kim have developed a product which solves all these purposes. Its named the Puri – Sea Water Desalination Bottle.

The Puri works on the concept of Reverse Osmosis and has been put in a very compressed and compact form inside the bottle. This regular sized bottle draws the saline out of the water and into the bottle’s yellow filter. The remaining water is then safe to drink, which could mean the difference between life and death in a sudden marine emergency. See the process flow of the bottle below.

Handy water purifier for travellers

Water borne diseases continue to rule the kingdom of ailments! Water is something we humans cannot stay without and the availability of clean drinking water is difficult when we are on the roads and travelling to far off places. The problem of clean drinking water is all the more prominent in third world countries. Grayl, which is a Seattle based startup has come up with a brilliant handy solution to this clean drinking water problem.

The device has G3+ Three technologies in one for clean, safe water
G1 – Triple charged mesh captures germs (protozoa, bacteria, and viruses)
G2 – Ultra-powdered activated carbon from natural coconut husks filters odor, flavor, industrial and pharmaceutical chemicals, and heavy metals
G3- Antimicrobial agent to keep it fresh between uses

To put it simply the device consists of a double-walled container with a mesh filter system contained within the base of the inner cup. Once the outer cup has been filled with water, the user then places the inner cup inside and pushes down, forcing the liquid through the filter. The filter combines three technologies to ensure the water is properly purified: a triple charged mesh the capture germs, a layer of ultra-powdered activated carbon and an antimicrobial agent to keep the filter fresh between uses.

GRAYL is effective against disease causing water-borne pathogens, metals, chemicals, flavor and odor. This innovative idea could help millions of people in the various parts of the world where clean drinking water is a LUXURY!
