BREAKTHROUGH TECHNOLOGY FOR WATER

Every week someone comes along with new technology to change the world. Well here are two ideas that just may. The first is an Australian company that believes it has created the world’s greenest bottled water brand. Its bottling plant is entirely powered by hydroelectric and wind energy; the bottles are 100% biodegradable. Many others are also working along similar lines. This one is called Good Vibes For You (GVFY). Let’s see how it progresses. The other is a remarkable new way of purifying water by solar disinfection. I quote from greenprophet.com … “The method is almost cost-free and is now being used in many developing countries to make well and tap water safe for human consumption. “The SODIS purification process involves filling a number of 1.5 or 2 litre plastic bottles about three quarters full of clear water (if the available water is cloudy, it should first be filtered through a layer of sand). The bottle is then shaken vigorously to mix sufficient air with the water, and then filled to the top with more water and closed. The filled bottles are then placed on a metal or concrete surface (like the roof of a building or house) and left in the sun for at least 6 hours, or until hot to the touch. The bottles should then be taken inside and allowed to cool before being opened for use. “The SODIS water purification process utilises the sun’s ultraviolet rays to purify the water, killing harmful bacterial growth and other disease causing organisms. To enable the water to heat faster, paint one side of the bottle black and then place the bottle on a roof or other surface with the black side down. This acts mike a miniature sun boiler, and works on a similar principle as solar water heater collecting plates.”
