The present invention relates to a method for supplying oxygen to a water purification process, said method comprising providing an oxygen carrier of at least one copolymer of dimethylsiloxane, ethylene oxide and propylene oxide, adding said oxygen carrier to the water purifying process, and contracting said oxygen carrier with an oxygen containing gas. The invention further relates to the use of at least one copolymer of dimethyl-siloxane, ethylene oxide and propylene oxide, as an oxygen carrier in a water purification process.
L'invention concerne un procédé d'apport d'oxygène dans un processus de purification d'eau. Le procédé comporte les étapes consistant à : prévoir un transporteur d'oxygène constitué d'au moins un copolymère de diméthylsiloxane, d'oxyde d'éthylène et d'oxyde de propylène ; ajouter le transporteur d'oxygène au processus de purification d'eau ; et mettre en contact le transporteur d'oxygène avec un gaz contenant de l'oxygène. L'invention concerne de plus l'utilisation d'au moins un copolymère de diméthylsiloxane, d'oxyde d'éthylène et d'oxyde de propylène comme transporteur d'oxygène dans un processus de purification d'eau.
