Swedish company Solvatten recently began distributing its user-friendly solar water sterilization jug in countries like drought-afflicted Somalia. The device disinfects up to 10 liters of water in two or more hours, depending on conditions. To use it, you just fill the jug, open it like a book right down the middle and place it in the sun. Clear plastic panels expose microbes in the water to UV rays while the black plastic interior absorbs radiation to heat the water. You’ll know the water is ready to drink when you see a smiley face on the jug’s heat sensor. Since people often cook over wood fires in rural developing regions and this device cuts out the need to boil untreated water, it can also reduce deforestation, improve indoor air quality, and even save lives.

    The initiative is to treat the water before use. I’ve heard of so called living machines that can filter water to drinkable standards. In the near future we’ll recycle all our waste water for immediate human consumption. The same technology that is used aboard the space station. In the not to distant future, all current and expected water treatment technologies are gonna be rendered obsolete by a new technology; Nano membranes. They function on the size of the gaps of linked carbon atoms to restrict most particles to flow through it. Water molecules are barely small enough to fit through thus must be force through at high pressure, but prevent larger particles like bacteria, prions, poisons, viruses, salts and other particles which are too large to fit. It’s the same stuff they propose to use for desalinating water from the sea which will render most current desalination technology obsolete as well. Treatment or desalination will be interlinked to provide water needs and with far less energy needed to do it and the costs of doing either is gonna be comparable and superior to previous technology which require lots of mechanical parts to separate and lots of chemical separators and disinfectants. If nano membranes can be mass produced we can distribute portable units that are hand powered to provide drinking water to developing nations.
