Process for the treatment of contaminated water by means of adsorption and nanofiltration

摘要

A process for the treatment of water contaminated by polar and/or apolar organic compounds, and/or by heavy metal salts, and/or by oil dispersed or in emulsion, comprises sending said contaminated water to a system comprising: at least one adsorption (3) unit including at least one microporous or mesoporous alumina-silicate; at least one nanofiltration unit (7) including at least one hydrophilic nanofiltration membrane; wherein said hydrophilic nanofiltration membrane has a contact angle with water lower than or equal to 45°, preferably ranging from 25° to 40°.
