Researchers at INL havedeveloped methods and systems for the removal of arsenic from water at a cost projectedto be below $0.15 per thousand gallons. Utilizing Nano-sized particles,extremely high reaction rates facilitate rapid, selective arsenic removal evenat low (10 ppb) concentrations. The Nano sorbent has an arsenic “loading”factor seven to 100 times greater than existing adsorbents, and can beregenerated without appreciable loss of capacity multiple times, reducing wasteand operating costs.
