Abstract: A method for reducing the amount of acrylamide in recovered water from a fryer stack. This invention provides a method to treat acrylamide in the waste water/process water. Organic compounds such as phenols, acrylamide and phenolic compounds can be oxidized in the presence of oxidizing compounds like hypo and Fenton reagent. Fenton reagent is a product of reaction of Iron Salts (like Ferrous Sulphate-FeSO4) and Hydrogen Peroxide (H2O2). It generates OH* (radical) which has significantly more oxidation power compared to traditional oxidizing agents such as Chlorine . The fryer stack water is collected and treated using Fenton reagent such that the Acrylamide levels are reduced to less than 0.1 ppb in the recovered water.
