Abstract
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.
Claims22
A semipermeable filtration membrane (102) suitable for the purification of a liquid capable of producing ozone, the filtration membrane (102) including 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 active surface (102a) being made of a dielectric material, the electrically conductive lines (122, 124) forming interleaved anodes (122) and cathodes (124) that are spaced apart from one another.
A method of filtering a liquid containing water, the method including:
- passing the liquid through a semipermeable filtration membrane (102);
- generating ozone and other mixed oxidants using electrical power provided to an ozone producing circuit (120) disposed directly upon an active surface of a dielectric material (102a) of the filtration membrane (102);
- whereby the generated ozone and the other mixed oxidants kill microorganisms and chemically break down organic molecules that may be present on the active surface (102a).
A method of manufacturing a device (100) suitable for the purification of a liquid capable of producing ozone, the method including:
- providing a semipermeable filtration membrane (102) having an active surface (102a) made of a dielectric material;
- and
- disposing an ozone producing circuit (120) directly upon the active surface (102a) of the filtration membrane (102), the ozone producing circuit (120) having a plurality of electrically conductive lines (122, 124) forming spaced-apart and interleaved anodes (122) and cathodes (124).
