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.
