摘要： 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.

摘要： Continuous flow water treatment systems, devices and methods that reduce the costs associated with using oxidizing agents in water treatment by maximizing mixing energy with pressure of the solution in a continuous flow system. The systems comprise an inflow conduit that provides water to be treated to a mixing chamber in a housing, a first chemical injector mounted into either the inflow conduit or the housing that provides an oxidizing agent into the water flow, a driven impeller mounted within the mixing chamber that maintains the flow of fluid through the apparatus and provides agitation to the fluid within the mixing chamber, and an outflow conduit for expelling the treated water from the mixing chamber. The outflow conduit may be pressurized to increase the mixing energy in the mixing chamber.
