“Novel” technology in the Alaskan Situation
In this presentation by Aaron D. Dotson, Ph.D., P.E., at the University of Alaska Anchorage, various novel technologies for water and sanitation innovations in the Arctic are discussed. The talk covers the risks associated with truly novel technologies, the need for realistically novel approaches integrating proven technologies, implemented examples like ultra-and nano-filtration for drinking water, and broad ideas for decentralized treatment. The importance of applied research and pilot demonstrations in real-world situations is emphasized.

Novel technology in the Alaskan Situation Aaron D. Dotson, Ph.D., P.E. University of Alaska Anchorage 2ndAnnual Water and Sanitation Innovations for the Arctic The Hotel Captain Cook, January 26th, 2012
Novel From Merriam-Webster Dictionary Online new and not resembling something formally known or used
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
Risk Truly novel technologies have inherent risk Not tried and true O&M unknowns Staff training requirements The Alaska Factor
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
Implemented Examples Drinking Water Ultra- and Nano-filtration Tubular Membranes Origins in food processing industry Wastewater Subsurface Injection Common place for oil & gas industry
Broad Ideas Other industries technologies Multiple levels of quality Decentralized treatment Point-of-Use / On-site Clustering Reduced Design Life Operating Techniques/Monitoring/Regionalization
How? Applied Research May not directly result in construction Pilot/Demonstration Real systems in real situations
