Ultimate oxygen

The theoretical chemical (or ultimate) oxygen demand, or ThCOD (BODU), can be calculated for a wastewater with relatively few oxidizable components. The procedure requires one to calculate the equivalent oxygen concentration necessary for the complete stoichiometric oxidation of each of the wastewater components to its corresponding highest oxidation state and sum them for the total wastewater ThCOD. Carbonaceous components of wastewater generally considered to be fully... [Pg.558]

A wastewater contains 250mg/L benzoic acid, C6H5COOH. What is the ultimate oxygen demand (BODU) of this water The molecular weight of benzoic acid is 122. [Pg.559]

As described in the previous problem, the ultimate oxygen demand is a calculated oxygen demand that assumes oxidation of all species to their most highly oxidized stable form CO2, H2O, etc. [Pg.559]

Although H202 will react with bromine to give, ultimately, oxygen and HBr [9], this decomposition reaction is very slow compared to the formation of bromine and has little effect on process economics. Interox has also shown that a plant to recover 200 tonnes per annum of bromine would not have a significant cost when compared to the operating plant and would have a payback period of only 1 to 2 years. [Pg.123]

In summary, the ultimate oxygen storage which as discussed above can be related to the reduction behaviour of the Ce02 based systems, is strongly related to the morphology of the CeC>2 particles, the presence of the supported metal and the nature of the reducing agent. [Pg.194]

The chemical oxygen demand (COD) test requires less time and results are more reproducible than that for BOD determination. It is a parameter established for the assessment of the amount of both organic and inorganic matter contained in a water body and measures the ultimate oxygen consumption of a sample, being widely employed in analytical laboratories for monitoring water quality. [Pg.196]
