Water. This is more important than food or fuel. The world’s population is increasing while the worlds’ water supply is not. There are only two frontiers left to supply water; either to purify the wastewater for recycle in industrial facilities or purify seawater. Neither of these frontiers have been conquered cost effectively with existing technology.
For years membranes and ion exchange have been used to lower TDS from water and wastewater, none of which is economical, practical or efficient as TDS levels increase beyond 35,000 PPM. Availability of technology for low power consumption and powerful to purify the primary pollutants is not available in a single technology platform. In many parts of the world safe fresh water is not available to support the population, or that water will be the major economic, environmental, and political issue in the next century yet, this entire field is characterized by mature technology with manufacturers that refuse to embrace a disruptive technology. So the product cycles are measured in decades by the consumer. But a new technology has been developed such as the Electronic Water Purifier (EWP) over the last 10 years that has low operating costs, low rejection waste water, low capital, no chemicals, small footprint and is now from POU to in large commercial sizes. This technology will challenge traditional technologies in water purification.
