Composition for treating groundwater contamination
View Patent ↗A composition comprising phospholipid and surfactant for remediating water, such as groundwater, contaminated with halogenated organic compounds. The composition may further comprise a free iron source. The composition is used in a method for remediating contaminated water, such as groundwater, through bioremediation.
1. A composition for remediating groundwater contaminated with halogenated organic compounds comprising from 30% to 70% phospholipid, 5% to 10% surfactant and 20% to 65% of a free iron source.
2. The composition of claim 1 wherein the free iron source is selected from the group consisting of ferric chloride and ferric sulfate.
3. The composition of claim 2 wherein the ferric chloride is in a solution with an acid.
4. The composition of claim 1 wherein the phospholipid is selected from the group consisting of lecithin, phosphatidyldiglycerol, phosphatidylinositol, phosphatidylserine, phosphatidylethanolamine and combinations thereof.
5. The composition of claim 1 wherein the surfactant is selected from the group consisting of polysorbate, polyoxyethylene stearate, sorbitan fatty acid ester and combinations thereof.
6. The composition of claim 5 wherein the polysorbate is selected from the group consisting of polyoxyethylene (20) sorbitan monolaurate, polyoxyethylene (20) sorbitan monopalmitate, polyoxyethylene (20) sorbitan monostearate, polyoxyethylene (20) sorbitan tristearate and polyoxyethylene (20) sorbitan monoleate.
