A membrane (8) is used as a collection substrate in an electrostatic precipitator. Possible material choices include fibers in the form of woven mats, screens, made from stainless steel wires or fiber reinforced polymer composite membranes. The, membranes have a tensile bias (14) applied during operation and have impulse , tensile, forces applied during a dust removal step. By combining a dry electrostatic precipitator, membrane field with wet-film cleaning field it may be possible to improve , collection efficiencies both by reducing turbulence and eliminating re-entrainment losses due to, rapping. Through implementation of new materials that resist hostile electrostatic, precipitator …

Why it's free to use
- Filed June 9, 1999 and granted May 21, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 9, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 9, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
