BOD and COD Removal Hydrogen Peroxide - Knowledge ...

Hydrogen peroxide can be used alone or with catalysts – such as iron (Fe2+ or Fe3+), UV light, ozone (O3) and alkali – to, oxidize BOD/COD contributing compounds, in wastewaters. The type of oxidation needed depends on the type of BOD/COD present. This relationship is present in the figure below.

Hydrogen peroxide and peracetic acid in wastewater over time could be modeled as a second-order decay, with the decay "constant" being a function of the initial concentration of, peroxycompounds., This function was the same for both hydrogen peroxide and peracetic acid, possibly indicating similar decomposition pathways in wastewater matrices.

1/6/2001, · A, solution, in COD concentration of 60 g/L was prepared with pure DSD-acid, which is one of the major constituents of, DSD-acid wastewater,, and its pH was adjusted to 2.5. FeSO 4 solution was added to adjust the concentration of Fe 2+ in the solution to 3.60 mmol/L. H 2 O 2 solution (30%) was dripped into the, solution, and the change of SO 4 2− concentration in the solution was measured after …

It is likely that the optimal application dose for hydrogen peroxide to wastewater treatment ponds is above 0.148 gL-1. The minimum detection limit for microcystin and nodularin concentration was 0.1 μgL-1, and all samples tested within this study were below this concentration according to the analysis.

Hence, ,hydrogen peroxide, was infeasible as a disinfectant for this ,application,. On the other hand, the peracetic ,acid, dose needed to achieve the target fecal coliform level was only 0.6 to 1.6 mg/L. Therefore, peracetic ,acid, seems to be a promising disinfectant for physicochemical or primary effluent, or combined sewer overflows.
