Webexperiments, so that oxygen absorptions might be calculated to the basis qf dry sludge and corrected even further for the content of organic matter. 1 ^Typical data and computations for one experiment are shown in Table I. Table I Absorption of Oxygen by Activated Sludge Capacity of cylinder = 1080 cc. Volume of dilution water = 14200 cc. WebUsing a simple static model, a gas phase balance on oxygen and carbon dioxide, sOTR(N) values were also calculated from off-gas testing. Comparison of sOTR(N) to sOTR and sOUR for carbon oxidation (sOUR(C)) to nitrification (sOUR(N)) at different loading …
