Process for treating water using atomized ferrous powders containing 0.25 to 4 wt carbon and 1 to 6 wt oxygen

摘要

A process for treating contaminated water in which water contaminated with a volatile organic compound is placed within a volume of iron powder granules which have been water atomized by striking a stream of molten iron with water jets and drying the resulting iron powder. The iron powder granules contain iron, carbon and oxygen, wherein carbon is contained from 0.25 to 4 wt. % and oxygen is contained from 1 to 6 wt. %. The contaminated water is passed through or contacts the iron powder granules, whereby the contaminant is remediated.
