Abstract: A synergistic composition can be used to treat water containing nitrogen compounds and phosphorus compounds. The synergistic composition includes iron filings, clay particles, aluminum particles, and sand particles. The iron filings, clay particles, and aluminum particles act synergistically to remove nitrogen compounds and phosphorus compounds from water. Specifically, the clay particles attract the nitrogen compounds and the phosphorus compounds to be absorbed onto a surface of the iron filings and the clay particles. The aluminum particles react with the nitrogen compounds via an oxidation reaction to form ammonia compounds, and react with the phosphorus compounds to produce aluminum phosphate. As such, the synergistic relationship between the iron filings, clay particles, and aluminum particles remove nitrogen and phosphorus compounds from water and recover the compounds in usable forms, namely, ammonia and aluminum phosphate.

Abstract: Described herein relates to an optimum, low maintenance and low-cost filtration media which may be implemented near a source water location as a pretreatment to remove tannic acid and/or humic acid (color) from dissolved natural organic matter (NOM) (i.e., tannic acid, humic acid) to impede the prompt production of disinfection by-products collectively termed trihalomethanes in drinking water treatment processes. In an embodiment, the filtration media may comprise a composition having a ratio of at least 83% sand, at most 5% clay, at most 6% ZVI and at most 6% perlite by percent volume.

Abstract: Described herein relates to a low-cost, synergistic, and/or green sorption media and methods thereof capable of removing MC-LR in-situ over different landscapes. The synergistic composition may include a mixture of a plurality of sand particles, a plurality of biochar particles, a plurality of clay particles, a plurality of zero-valent iron (hereinafter “ZVI”) iron molecules, and/or a plurality of perlite particles. In certain embodiments, the plurality of clay particles, plurality of ZVI molecules, and/or plurality of perlite particles may have an approximately equal volume percentage, with the volume percentage being less than or equal to a volume percentage of the plurality of biochar particles. Furthermore, the synergistic composition may be homogenously mixed and/or included in a media chamber of a filtration system.

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 most 5 volume (vol) % of the composition, sand particles comprising at least 80 vol % of the composition, and clay particles comprising at most 5 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.

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 leak 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.
