Investigation of an ozone-filter system for color and iron removal at low temperaturesThe application of ozonation as a disinfectant and as a treatment process for both water and wastewater has been increasing in recent years. The study of ozone application to Arctic and subarctic waters, which are normally at low temperatures, has been limited. Many portions of the Alaskan Arctic and subarctic are plagued with waters which exceed the 1962 Drinking Water Standards for one or more parameters. The iron content and color of the water are among the most common offenders. This project was directed toward the examination of a method for water treatment utilizing ozone to meet the iron and color limits for drinking water. The three principle objectives of the project were: (1) to examine the effect of ozone on several known qualities of water, (2) to examine the effect of ozone on representative samples of surface and ground water, and (3) to develop a laboratory scale system for iron and color removal utilizing ozone followed by sand filtration.
Land Disposal of Secondary Lagoon Effluents (Pilot Project)The principle objective of this effort was to assist the US Army, Cold Regions Research and Engineering Laboratory, in conducting a pilot land disposal project in the interior region of Alaska. This project was a preliminary investigation of the feasibility of land disposal of secondary effluent from an aerated lagoon during the summer months. The hope was to examine the possible use of this technique to meet 1977 standards for the quality of secondary effluents.
