Webb27 sep. 2006 · Results have been compared to those obtained from closed bottle tests (301D). Problems with using activated sewage as an inoculum have been demonstrated, as respirometry curves were biphasic, and the recorded biological oxygen demand (BOD) was higher than the calculated theoretical oxygen demand (ThOD). WebbTheoretical oxygen demand (ThOD) is the stoichiometric amount of oxygen required to oxidize a compound to end products such as CO2, NH3, H2PO42, SO422, and H2O. CODCr can be estimated from ThOD using the following equation:7 CODCr = a3 ThOD, (1) where a is an empirical constant. The ThOD for each of the chemicals in this study was chinche gris
