Abstract
Methods for treating regulated waters with low levels of oxidizing halogens and hydrogen peroxide are disclosed, wherein the halogen-containing compound is provided with an erosion control agent such as glycoluril, and the hydrogen peroxide is provided with a hydrogen peroxide stabilizer such as a polyquaternary ammonium compound. Additional stabilizers to chelate metals and increase the half life of peroxide in aqueous solutions may also be added.
