Abstract: A process for the treatment of contaminated water comprises sending the contaminated water to a treatment system. The system comprises at least one adsorption (3) unit and at least one nano-filtration unit (7). The at least one adsorption (3) unit includes at least one microporous or mesoporous alumino-silicate and the at least one nano-filtration unit (7) includes at least one hydrophilic nano-filtration membrane. The hydrophilic nano-filtration membrane has a contact angle with water lower than or equal to 45°. The water is contaminated by polar and/or apolar organic compounds, and/or by heavy metal salts, and/or by oil dispersed or in emulsion.

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.

Abstract: A process is described for the treatment of water contaminated by apolar organic compounds and/or by heavy metals, which consists in circulating the water through a system comprising at least two types of zeolites having a silica/alumina ratio >50, placed in succession, wherein the first zeolite through which the water is passed is characterized by a high absorption capacity and structural channel dimensions ranging from 7 to 50 Å, whereas the second is characterized by a high removal capacity of molecules with a molecular diameter comparable with structural channel dimensions ranging from 5 to 7 Å.
