Problems solved by technology

Even if they could be kept separate from each other, due to their mutual positional relationship, putting each medium in the same container would actually make it difficult to use, or to replace only one medium without replacing the other medium
Another disadvantage is that, especially in small processing units with counter tops or taps, such as those with shower heads, there is often no way to allow media to be rinsed or backwashed, which would greatly extend the system and the life of the medium in question
[0005] Another disadvantage in many water treatment plants is that water passing through the treatment media generally flows in a direction that would cause the media to plug when in use
As a result, dirt or other contaminants removed by the media will become lodged in the media, accumulating to eventually clog the media or affect its treatment function

Embodiment Construction

[0038] A kind of multimedia liquid processing equipment 10 such as Figure 1-4 shown. In preferred applications, the unit 10 may be a counter top or under counter unit, or a faucet mounted unit, such as a shower head unit, for treating municipal or other potable water sources.

[0039] Apparatus 10 preferably includes a housing 12 having two chambers 14 and 16 therein, preferably containing different water treatment media 18 and 20 in associated chambers. The inner chamber 14 is preferably defined by vertical inner cylindrical side walls. Adjacent the bottom of chamber 14 is a perforated plate 24 which in turn provides a support plate for mesh screen 26 which supports process medium 18 when there is little or no flow through the apparatus.

[0040] A number of vertical slots 28 are provided at the top of side wall 22 . Preferably, the width of the slit decreases gradually through the thickness of the sidewall and along the direction of normal liquid use flow towards the cha...

Abstract

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 is provided with a rotatable valve and 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.

Description

[0001] The patent application of the present invention is a divisional application of the Chinese invention patent application with the application number 99120533.2, the application date being September 29, 1999, and the invention title being "Regeneration of Water Treatment Medium". technical field [0002] The present invention relates to the regeneration of water treatment medium, especially to a kind of water treatment equipment with one or several kinds of medium, the valve is used to selectively regenerate the medium and the method of regenerating the medium. Background technique [0003] Liquid treatment systems employing one or more liquid treatment media have been used in the past to treat various liquids such as water to remove impurities and contaminants therefrom. In some of these systems, various treatment media are employed in series relationship with each other so that one media can have a beneficial effect on the subsequent downstream media. For example, in ...
