Abstract
In a pressure swing adsorption system for the supply of enriched oxygen to a variable demand wastewater treatment system, the oxygen product to feed air ratio is increased during periods of reduced oxygen demand, with the enriched oxygen being supplied to the wastewater treatment system at lower purity levels during such periods of reduced demand than the purity levels supplied under maximum demand conditions. Operation in this manner enables oxygen recovery to be enhanced and the power requirements to be reduced under such variable demand conditions.
