Title (EN) FILTER AND METHOD FOR ITS PRODUCTION
(FR) FILTRE ET SON PROCÉDÉ DE FABRICATION
Abstract: front page image
(EN)A filter (10) for cooling, ventilation, air-conditioning, heating and air purifying plants comprises a filtering support (12) with which one or more bactericidal metals (14) are stably associated, chosen from a group comprising: noble metals such as silver, gold, platinum, or heavy metals such as iron, copper, manganese, zinc, lithium, or an organic bactericidal molecule chosen from quaternary ammonium salts. The metals (14) are taken individually or in a mixture with each other, or individually or mixed with the quaternary ammonium salt. The filtering support (12) comprises, in concentration in weight higher than or equal to about 15%, a chitosan- based biopolymer to which said metals (14) and/or said quaternary ammonium salt are chemically bonded, both inside the biopolymer and on its surface.
(FR)L'invention concerne un filtre (10) pour des installations de refroidissement, de ventilation, de conditionnement d'air, de chauffage et de purification d'air, qui comprend un support de filtration (12) avec lequel un ou plusieurs métaux bactéricides (14) sont associés de façon stable, choisis dans un groupe comprenant : les métaux nobles tels que l'argent, l'or, le platine, ou les métaux lourds tels que le fer, le cuivre, le manganèse, le zinc, le lithium ou une molécule bactéricide organique choisie parmi les sels d'ammonium quaternaire. Les métaux (14) sont pris individuellement ou dans un mélange entre eux, ou individuellement ou mélangés avec le sel d'ammonium quaternaire. Le support de filtration (12) comprend, en concentration en poids supérieure ou égale à environ 15 %, un biopolymère à base de chitosane auquel lesdits métaux (14) et/ou ledit sel d'ammonium quaternaire sont chimiquement liés, à la fois à l'intérieur du biopolymère et sur sa surface.
