Abstract
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.The work reported on herein was done under Contract No. RFP DACA 897l-
R-0006 from the U. S. Army Cold Regions Research and Engineering
Laboratory, Hanover, New Hampshire
