Process for the treatment of contaminated water by means of a bifunctional system consisting of iron and zeolites

Abstract

A process is described for the treatment of water contaminated by metals with a high oxidation degree, aliphatic compounds, aromatic compounds, halogen-aromatic compounds, chlorinated alkane and alkene compounds or mixtures thereof, which consists in circulating the contaminated water through a reactive system consisting of metallic iron and a zeolite having a silica/alumina ratio>50, placed in succession, wherein the first element through which the water passes is iron.
