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 () unit including at least one microporous or mesoporous alumina-silicate; at least one nanofiltration unit () including at least one hydrophilic nanofiltration membrane; wherein said hydrophilic nanofiltration membrane has a contact angle with water lower than or equal to 45&#xb0;, preferably ranging from 25&#xb0; to 40&#xb0;.

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

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 &#x3e;50, placed in succession, wherein the first element through which the water passes is iron.

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

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 &#x3e;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 &#x212b;, 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 &#x212b;.

Process for the treatment of contaminated water based on the use of apolar zeolites having different characteristics

The invention relates to a process for the hydroxylation of aromatic hydrocarbons by direct oxidation with hydrogen peroxide. The process is carried out in the presence of a catalyst comprising:

Process for the hydroxylation of aromatic hydrocarbons

A method for preparing nontoxic, edible proteinic concentrates adapted also for human nutrition, is disclosed according to which undesirable compounds such as polyphenols (e.g. chlorogenic and caffeic acids) are complexed by aluminum salts to prevent oxidizing these polyphenols to quinones. It is important that aluminum be constantly kept in soluble form to prevent it from being precipitated together with the proteins when protein-precipitating acidification is carried out. Citric acid has been found to be the best complexing agent.
