Abstract
Official abstract text for this publication.
A slow-release method for treating non-point source pollutants traveling in water runoff, such as urban water runoff. Method embodiments include the use of slow-release advanced oxidation process forms (SR-AOPs) comprised of one or more water soluble salts in a matrix and/or forms producing hydrogen peroxide, persulfate anion, and/or permanganate. One or more of such forms may be placed along with one or more slow-release iron forms in the path of runoff water as it flows through a storm sewer system, such that an amount of the water soluble salt(s) and/or hydroxyl radicals (Fenton's reagent), persulfate radicals, or permanganate are slowly released into the runoff water to oxidize the pollutants contained therein.
First claim
Opening claim text (preview).
What is claimed is: 1 . A slow-release method of treating non-point source pollutants in water runoff as said runoff travels through a storm sewer system, comprising: providing at least one slow-release advanced oxidation process (SR-AOP) form comprised of a water soluble salt dispersed within a matrix; placing the at least one form in at least one or more inlets of the storm sewer system; and causing runoff water to contact the at least one form as it flows through the stor…
