SOLVING THE MYSTERY OF HIGH PURITY OXYGEN PLANTS – EFFECT OF PRESSURE ON FLOW DISTRIBUTION
The Sacramento regional wastewater treatment plant (SRWTP) has experienced significant variations in the flow split among it is 12 oxygen basins. An extensive evaluation of the pressure effect on flow distribution to high purity oxygen oxidation tanks was conducted at the SRWTP. The evaluation included field testing, mathematical modeling and laboratory testing. Evaluations indicated that head pressure in the oxygen tanks plays major role in distribution the incoming flow to the basins. Also, differential pressure between the tanks could adversely affect flow distribution and treatment capacity at the plant. A 1:20 scale physical model was constructed to verify the findings from field testing as well as to identify recommendations for equalizing the pressure distribution between the tanks and improving flow distribution to the tanks.
