Abstract

A contaminant eco-remedy (1) has a colloid-active detergent with colloidal microspheres of a predetermined particle size in an alkanol amide. The alkanol amide is prepared by condensation of a predetermined vegetable fatty acid with an alkanol amine, ethanol, distilled water, and ethylene diamine tetraacetic acid in predetermined proportions. The vegetable fatty acid has a saponification value of about 271 and an acid value of about 269. The colloid-active detergent is diluted with specific concentration of water, nutrients and oxidative agents for degradation and enhanced bioremediation of organic compounds that are oxidation-reduced to non-contaminant mixtures containing nitrates, carbon dioxide, oxygen and water. From organic contaminants containing chlorine and sulphur groups, the non-contaminant mixtures may contain HCL, NACL, H₂S, and SO₃. A method for using the contaminant eco-remedy includes chemical degradation in a treatment tank (2), biodegradation by bacteria (aerobically or anaerobically) in a retention tank (6), degradation, soil flushing and bioremediation of contaminated targeted soil (15), a system tank (14) for the injection of the contaminant eco-remedy and the treated groundwater with injector tubes (17), extraction wells (20) and related circulation and handling equipment and a customized tank (28) that soil-washes organic compounds from contaminated soil with the contaminant eco-remedy to water phase eco-remediated wash waters.
