US Patent:

6984313, Jan 10, 2006

Filed:

Feb 8, 2005

Appl. No.:

10/717682

Inventors:

Farvell M. Mark - Phoenix AZ, US

International Classification:

C02F 9/12

US Classification:

210106, 210138, 210313, 210332, 210335

Abstract:

An automatic water filtration and purification system will allow a continuous water flow to downstream fixtures while simultaneously and automatically regularly flushing and cleaning in-path filter media. The automatic water filtration and purification system has at least one filter to remove impurities from a water in-path through-put. A cleaner is coupled to the at least one filter to clean the at least one filter. A controller is coupled to the at least one filter to regulate automatic operation of the cleaner wherein continuous operation of water flow to fixtures downstream of the at least one filter is essentially uninterrupted during the operation of the cleaner and the controller.

Appl. No.:

8/385740

Inventors:

Farvell M. Mark - Phoenix AZ

International Classification:

A61L 210
C02F 132

US Classification:

250438

Abstract:

The output of a mechanical/chemical water filter(s) is conveyed through tubes transparent to ultraviolet radiation disposed in proximity to a source of ultraviolet radiation having the capability of disinfecting the water flowing through the tubes. Each of the opposed ends of the tubes is supported within a cylindrical cavity of a support member and retained in sealed engagement by a tube circumscribing O-ring clamped about the tube by a plate detachably attached to the support member. Passageways within the support member channel the water into or out of the respective tube end. The source of ultraviolet radiation is secured to opposed support members in close proximity to the tubes to enhance the bacteria, virus and micro organism killing capability of the ultraviolet radiation source.

International Classification:

C02F 148

US Classification:

210259

Abstract:

A water purification system is disclosed comprising a reverse osmosis chamber coupled to a multi-pass ultraviolet chamber for irradiating water with ultraviolet light radiation both before and after the water passes through the reverse osmosis chamber. The multi-pass ultraviolet chamber provides a plurality of water conveying tubes in proximity to an ultraviolet light radiation source. The diameter of the conveying tubes is substantially larger than the diameter of conduits feeding the tubes. Accordingly, the water flow through the tubes decelerates, thereby increasing the duration of ultraviolet light radiation exposure to the water in the tubes. Additionally, a removable cover is located above the ultraviolet light bulb in order to facilitate easy replacement of the bulb.
