Regeneration of water treatment media

Attorney, Agent or Firm: Cook, Alex, McFarron, Manzo, Cummings & Mehler, Ltd.
Regeneration of water treatment media is disclosed which includes a water treatment unit having one or more media therein, and which upon initiation of flow of the water, imparts turbulence and abrasion to the treatment medium to automatically cleanse the medium of light solid contaminants, as well as contaminant coatings on the media. This greatly improves the operation of the media and extends its life. In addition, the water treatment unit disclosed may simply be rotated through any one of a number of positions between service, backwash, flush, off and/or bypass operational modes for further regeneration of the treatment media. |

DETAILED DESCRIPTION What I claim is: 1.
A fluid treatment unit comprising: a housing having a chamber therein which is of a given volume; a finely divided loose fluid treatment medium in the chamber and which occupies a volume which is substantially less than the given volume of the chamber when fluid to be treated is not flowing through said medium; an inlet to the chamber for introducing the fluid to be treated to the chamber and beneath the fluid treatment medium in the chamber; an outlet to the chamber downstream of the fluid treatment medium for discharging the fluid which has been treated from the chamber; and wherein said unit is constructed and arranged to lift said loose fluid treatment medium in a controlled manner upon initiation of flow of fluid to be treated from said inlet to separate, flush and remove any contaminants from said medium which may have accumulated on the medium, to suspend said medium during continuing flow of the fluid while restraining the rate at which the fluid treatment material is lifted, and to permit said medium to settle to the bottom of the chamber when the flow of fluid has ceased.
2.
The fluid treatment unit of claim 1, wherein said chamber has a height which is greater than its maximum width, and said chamber includes at least one portion intermediate its height which portion has a width substantially less than said maximum width to restrain the rate at which the medium is lifted in the chamber as the flow of fluid is initiated.
3.
The fluid treatment unit of claim 2, including a plurality of said portions spaced from each other along the length of the chamber.
4.
The fluid treatment unit of claim 2, wherein the cross-sectional area of said portion is about 5-50% of the cross-sectional area of said chamber at its said maximum width.
5.
The fluid treatment unit of claim 2, wherein the cross-sectional area of said portion is about 10% of the cross-sectional area of said chamber at its maximum width.
6.
The fluid treatment unit of claim 2, including an additional inlet intermediate the length of said chamber and which is associated with said lesser width portion to introduce additional fluid to be treated to the chamber adjacent said lesser width portion
