    Abstract: An apparatus and method for filtering a dirty air stream in a vacuum cleaner to obtain a clean air stream comprises subjecting the dirty air stream to a first cyclonic separation stage (32) to obtain a partially cleaned air sream and subjecting the partially cleaned air stream to an electronic filtration stage (50) and optionally a second cyclonic separation stage (60) to obtain the clean air stream. The electronic filtration stage (50) is optionally removable with a cyclonic cleaning stage from the vacuum cleaner. The electronic filtration stage (50) is optionally an electrostatic precipitator which utilizes air flow through the vacuum cleaner to generate the voltage used by the electrostatic precipitator.

    Abstract: A process of separating water from ambient air involves a liquid desiccant to first withdraw water from air and treatment of the liquid desiccant to produce water and regenerated desiccant. Water lean air is released to the atmosphere. Heat generated in the process is recycled. The drying capacity, or volume of water produced, of the system for a given energy input is favored over the production of dried air.

    Abstract: A method for treating a liquid comprising water with a gas comprising ozone comprises introducing the liquid to be treated into a treatment vessel, introducing the gas to treat the liquid into the treatment vessel and treating the liquid in the treatment vessel, pressurizing the treatment vessel and, using the pressure in the treatment vessel to dispense the treated liquid from the treatment vessel through a filter. An apparatus for treating the liquid is also disclosed.
