  1. “Novel” technology in the Alaskan Situation Aaron D. Dotson, Ph.D., P.E. University of Alaska Anchorage 2nd Annual Water and Sanitation Innovations for the Arctic The Hotel Captain Cook, January 26th, 2012

  2. “Novel” • From Merriam-Webster Dictionary Online “new and not resembling something formally known or used”

  3. Truly “novel” technologies • Nanoparticle impregnated sorbents/ion exchangers • Advanced Oxidation processes • Hydroxyl radical promoters • Plasmon oxidation • E-Beam • Exotic disinfectants • Exotic membranes These are not likely the technologies rural AK needs…

  4. Risk • Truly “novel” technologies have inherent risk • Not “tried and true” • O&M unknowns • Staff training requirements • The Alaska Factor

  5. Realistically “novel” • Proven technology from other fields • A combinations of technologies considering • current water/wastewater quality goals • future/variable water/wastewater quality goals • O&M feasibility • Delivery/Collection Paradigm • Optimization of Operation

  6. Implemented Examples Drinking Water • Ultra- and Nano-filtration Tubular Membranes • Origins in food processing industry Wastewater • Subsurface Injection • Common place for oil & gas industry

  7. Broad Ideas • Other industries technologies • Multiple levels of quality • Decentralized treatment • Point-of-Use / On-site • Clustering • Reduced Design Life • Operating Techniques/Monitoring/Regionalization

  8. How? • Applied Research • May not directly result in construction • Pilot/Demonstration • Real systems in real situations

  9. Thank you Aaron Dotson, Ph.D., P.E. Assistant Professor Civil Engineering University of Alaska-Anchorage (907)786-6041 addotson@alaska.edu
