METHOD OF PURIFICATION AND DECONTAMINATION OF THE WATER MEDIUMS Russian patent published in 2006 - IPC C02F1/28 C02F1/72 B01J20/02 

FIELD: purification of sewage, waste waters and recycled waters.

SUBSTANCE: the invention is pertaining to the field of purification of sewage, waste waters and recycled waters. The invention offers the filtration composition consisting of the adsorbent-catalyst based on the minerals and, if necessary, on the supporting layer in the form of grit. The adsorbent-catalyst contains the active components - oxides, hydroxides of metals and spinels of metals of the variable valence; the modifying agent - organic bases and-or heteropolyacids; the plasticizer - organosilicon compounds; the mineral carrier - clay,_{Al2O3, SiO - at the following contents of the components of the adsorbent-catalyst (in mass %): - the active component in the form of oxides, hydroxides and spinels - 15-50; - the organic bases and-or heteropoly acids - 1-2; - the organosilicon compounds - 1-2; - the mineral carrier - the rest. The invention allows to conduct the effective purification of the sewage and waters from the organics, suspended substances, metals, salts and E.coli.}

EFFECT: the invention allows to conduct the effective purification of the sewage and waters from the organics, suspended substances, metals, salts and E-coli.
