Abstract
The report discusses the use of pure oxygen in an activated sludge sewage treatment system. It produces effluents comparable in BOD and suspended solids to those of a parallel diffused aeration system with an aeration time of 3.6 hours. Consistently over 95% of the supplied oxygen was used in the reactor which employed co-current liquid and gas flow contacting. The microbial organisms visually were found to be essentially the same as a typical conventional system; however, their rate of activity was greater.
