Disinfecting the Water Using Peroxone


Quiz Questions

1.The ratio of direct oxidation with molecular ozone is relatively slow (10-5-107M-1sec-1) compared to hydroxyl radical oxidation (1012-1014M-1sec-1), but the concentration of ozone is relatively high.
True
False
2. A key difference between the ozone and peroxone processes is that the peroxone relies heavily on the direct oxidation of aqueous ozone while ozone process relies primarily on oxidation with hydroxyl radical.
True
False
3.Peroxone will oxidize the saturated organics and produce byproducts similar to those found in ozonation namely- aldehydes, ketones, peroxides, bromate ion, and biodegradable organics.
