Bio-Processes of the Oxidation Ditch When Subjected to a Sub-Arctic ClimateRanganathan, K. R.; Murphy, R. Sage (University of Alaska, Institute of Water Resources, 1972-05)Alaska's far northern area is sparsely populated primarily because of a severe climate which varies from northern temperate to Arctic. Construction and power costs are high. Skilled operating personnel are scarce and expensive, if available. Receiving streams are said to be delicate, particularily in the winter, when little possibility for reaeration exists due to a total ice cover. The oxidation ditch modification of the extended aeration activated sludge process appears to be well suited for the treatment of wastes in this environment. Past operating data on a plant of this type located in Interior Alaska (near Fairbanks) indicated it may be well suited to treat small volumes of domestic waste economically, with low sludge production, and minimal sensitivity to low temperatures.
