Abstract:

Because of the unacceptably high color and chlorine demand in surface waters at some remote U. S. Air Force radar sites in Alaska, a method was sought to remove these objectionable characteristics. Carbon filters and chemical treatment have proved either ineffective or too expensive. Treatment with hypochlorite was shown to be effective and acceptable in the laboratory, where samples showing from 40 to 70 units of color were successfully treated by chlorine doses ranging from 10 to 40 mg1. The rate of color removal was faster at the higher doses however, the chlorine residuals persisted for longer periods of time.
