US Patent 9475008 Semipermeable filtration membrane with integrated producing circuit

The filtration membrane (102) includes an ozone producing circuit (120) having a plurality of electrically conductive lines (122, 124) disposed directly upon an active surface (102a) of the filtration membrane (102). The electrically conductive lines (122, 124) form spaced-apart and interleaved anodes (122) and cathodes (124). Ozone and other mixed oxidants coming from the ozone producing circuit (120) will prevent and/or remove biofilm formations on the active surface (102a) without the need of an outside source of gas. They can also remove at least some undesirable dissolved gases from the liquid being purified.
