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).

WebbThe oxidation behavior of twenty organic chemicals from four different classes (sugars, benzene derivatives, alcohols and carboxyl acids) were investigated using the official chemical oxygen demand (COD) methods ( i.e., permanganate and dichromate methods) and their oxidation levels compared with the theoretical oxygen demand (ThOD) values. WebbTheoretical oxygen demand (ThOD) is the calculated amount of oxygen required to oxidize a test chemical to its final oxidation products. When the BOD is more than 60% of the ThOD, and the amounts of the chemical and its degradation products are less than 1% of the added chemical, ...
WebbThe amount of oxygen to require for oxidizing carbon atoms is CBOD, the amount required for oxidizing nitrogen atoms of organic material is NBOD, and CBOD+NBOD is considered theoretical oxygen demand (ThOD). Theoretically, we can use stoichiometry of the oxidation reaction of organic molecules to calculate the biochemical oxygen demands. WebbIf the ThOD cannot be obtained, the chemical oxygen demand (COD) may be experimentally determined and used as a less satisfactory alternative. This method is capable of testing samples that are highly soluble, poorly soluble, insoluble, volatile, involatile, and/or …
