Bag versus bottle? Puralytics’ new approach to pure portable water
Posted by Xeno on July 25, 2012
Heather Clancy – … the SolarBag, a new technology from water company Puralytics for purifying water on-the-go. The product could have implications for camping, international travel or for the emergency kit you’re supposed to keep in the trunk of your car.SolarBag uses sunlight-activated nanotechnology to remove bacteria, viruses and protozoa from water. As the image suggests, you could use the bag while camping to keep stocked up on water.It takes about three hours for the SolarBag to produce 3 liters of fresh water in direct sunlight four to six hours if it is cloudy. It can be used several times per day, and Puralytics said the bag can be reused hundreds of times before it needs to be replaced.The SolarBag exceeds U.S. Environmental Protection Agency guidelines for water purifiers, according to Puralytics. “The versatility and performance of the SolarBag makes it the best water purifier on the market for remote and emergency applications,” said Mark Owen, found and CEO of Puralytics. “It’s light, simple to use, easily transportable and reliable.”Right now, SolarBag can be bought from Amazon about $77 or from The Sportsman’s Guide about $80. It is available in 30 countries, where it is being used to help increase access to potable water in developing countries. …
Five photochemical processes work together synergistically to break down or remove contaminants from water. This process actually destroys contaminants, rather than capturing them and creating a hazardous waste disposal problem.
Photocatalytic Oxidation - LEDs or sunlight activate a nanotechnology coated mesh to generate hydroxyl radicals (OH-) which break apart chemical contaminants rendering them inert.
Photocatalytic Reduction – Reduces toxic species such as mercury (Hg II), silver (Ag I), arsenic (As V, and chromium (Cr VI) to more readily adsorbed materials.
Photolysis – Direct disassociation of contaminants by high intensity UV light, including atrazine, amoxicillin, DEET, and all estrogenic chemicals.
Photoadsorption – The catalyst strongly adsorbs heavy metals including mercury, lead, selenium, and arsenic, permanganate, and other compounds.
Photo Disinfection – Multiple wavelengths and high intensity UV disinfect pathogens more effectively than standard UV germicidal.
Puralytics has pioneered an entirely new way to purify water using light-activated nanotechnology, enabling pure water in places and applications where it was not possible before.
Puralytics is a privately funded technology company located in Beaverton, Oregon.
While there are many ways to treat water including chemical, thermal, filtration, and separation technologies, Puralytics has pioneered photochemical purification technologies which have compelling advantages in many applications.
