Two Prizes for Expanding Usable Water Supplies

The Bureau of Reclamation is launching two new prize challenges, Arsenic Sensor Challenge and More Water, Less Concentrate.

This is the first stage for each challenge. Subsequent stages with larger prize purses are planned for testing and demonstrating the most promising technologies.

The Arsenic Sensor Challenge seeks to identify new or improved sensors, devices or test kits to measure arsenic in water in natural and engineered systems.

Current analytical methods are suitable for ensuring regulatory compliance. However, Reclamation and its collaborators identified a need for rapid, low-cost monitoring of arsenic that would benefit water treatment plant operations, wastewater monitoring, contaminated site remediation, private well owners, scientific research, and other interested parties.

The More Water, Less Concentrate prize challenge seeks innovative solutions to expand usable water supplies by maximizing fresh water production from inland desalination systems in a cost effective and environmentally sound manner.

Many inland communities are exploring desalination as a method to provide a new source of water. This challenge may help them by minimizing the concentrate stream volume and associated handling costs while maximizing the usable water produced by the process.

1. The technology of Condensing Flue Gas Heat Recovery is designed to recover/remove the heat energy from the exhaust of combusted fossil fuels. Power plants have a lot of combustred exhaust. When the heat energy is removed, water is created. If a power plant recovers just 20% of this water from it's exhaust, it could be self sufficient. If it were to recover more it could be a water supplier to the local community. This distilled water is very useable.

   Water can also be created at large commercial buildings and at industry that consume large volumes of natural gas. In every 1 million Btu's of combusted natural gas are 5 gallons of recoverable distilled water. Taking the heat energy out of this waste exhaust and utilizing it will also help in the battle against global warming.

   For every 1 million Btu's of heat energy that is recovered from this combusted natural gas and is utilized, 117 lbs of CO2 will not be put into the atmosphere.

   Increasing Energy Efficiency will not only help conserve our water needs but also it will help to battle Climate Change.

2. Congratulations for launching prize challenge “The Arsenic Sensor Challenge”.

   The greatest threat to public health from arsenic originates from inorganic arsenic which is present in the groundwater of a number of countries, including Argentina, Bangladesh, Chile, China, India, Mexico, the United States of America, as well as Serbia, and in particular Vojvodina province.

   Let’s hope that the new test kit will be available in near future for widespread use.

   1. How can I get support for my new innovative technological solution for drinking water saveing systems from invisible leakage and contamination control system the technological solution is new in the field and also the global water sector Now at a time I can manufacture prototype And finished pilot test by domestic regions with best results.

      So I need global partners and financial support?
