New Technology Cleans Dangerous Water

Science News has an article on a low cost home treatment for highly contaminated water. The new treatment turns even dark, foul-smelling, germ-laden water into a drink as clean as most U.S. tap water. This could be a life saver for people in third world countries or any other country where it is necessary for the people to drink contaminated river water in order to survive.

  1. My first reaction was “Okay, it’s a patented process, and P&G probably stands to reap billions from the third world.” But not only was I completely unable to find a US patent on the process (“disinfectant AND flocculant AND procter” turns up a new, exciting form of baby wipe), the product turns out to be fairly cheap — $0.10US for a packet good for 10 liters, except for emergency aid, where they plan to sell it at cost of 3.5 cents per packet. The process is apparently a small-scale version of the same process used in municipal wastewater treatment plants. And neither Forbes nor P&G themselves mention a patent. I wonder how difficult it would be for this to be manufactured locally.

  2. This should be useful in Iraq where the people are forced to drink river water
