Abstract: A method of water treatment includes flowing water that includes nitrogen and phosphorus compounds through a sorption media composition within at least one chamber of a water treatment system. The composition comprises iron filings comprising at least 5 volume (vol) % of the composition, sand particles comprising at least 10 vol % of the composition; and clay particles comprising at least 2 vol % of the composition. The iron filings, sand particles, and clay particles are mixed together. During the flowing the clay particles attract the nitrogen and phosphorus compounds which become absorbed onto a surface of the iron filings and the clay resulting in a removal of the nitrogen and phosphorus compounds and the generation of reaction products. Nitrogen and phosphorus are then recovered from the reaction products.
