ABSTRACT:
A method and apparatus for removing contaminants such as heavy metals and organic pollutants from contaminated water using waste cast steel shot blast fines is described. Shot blast fines were hitherto disposed of by the iron processors at significant cost. In another embodiment, waste shot blast fines are used to fix heavy metal and organic contaminants in groundwater and water runoff from contaminated landfills and industrial sites.
