Description
BACKGROUND

Ozone contains three atoms of oxygen (O3) that is different than the two atoms oxygen (O2) in breathable air. Ozone may also be known as “activated oxygen.” The oxidizing properties of ozone can reduce or eliminate taste and odor problems. Furthermore, ozone is a powerful sterilant that can be used as an effective disinfectant. In some applications, ozone can effectively kill bacteria, viruses, microorganisms, and many other pathogens. Ozone is commonly used to treat and disinfect water.

DETAILED DESCRIPTION

Referring now to the drawings, embodiments of systems and methods of a water treatment system using ozone as a sterilant or disinfectant are disclosed in the present disclosure. The water treatment system is portable with all the working components being self-contained in an easy to carry unit, for example, personal and family size containers or water buckets.



FIG. 1 is a diagram illustrating a water treatment system 100 using ozone according to one embodiment. The water treatment system 100 includes a container 102 for holding water or any desired fluid. Water can be introduced into the container 102 via an inlet 104. In some examples, a funnel 106 or the like may be connected to the inlet 104 for guiding and directing water into the container 102. The funnel 106 is optional and may be omitted in some embodiments. Water entering the container 102 is treated by a water treatment device 108 that is in fluid communication with the inlet 104 that may be located at a top or upper portion of the container 102. For example, the water treatment device may be attached to a lid 103, top, or cover of the container. The water treatment device 108 is configured to filter and disinfect the water, for example, using ozone as a disinfectant. However, this disclosure is not limited to using ozone as a disinfectant. The treated and disinfected water is stored in the container 102 for later use. In some embodiments, an optional spigot 110 or the like may be fitted near the bottom portion of the container 102 to allow the filtered and disinfected water to be discharged. In some embodiments, the water treatment device 108 may receive a supply of ozone (e.g., O3) or ozone-mixed air 112 from an ozone supply. Any suitable ozone source may be used to supply the ozone.



FIG. 2 is a diagram illustrating an ozone supply 200 according to one embodiment. The ozone supply 200 includes an air pump 202 and an ozone generator 204 for generating ozone (e.g., O3). In operation, the air pump 202 generates an air stream that is mixed with ozone generated by the ozone generator 204. The air stream may have a pressure greater than atmospheric pressure or any desired pressure. The ozone-mixed air stream or ozone may be supplied to the water treatment device 108 to disinfect the filtered water. For example, the ozone generator 204 may be connected to the water treatment device 108 by a hose, conduit, or tubing that carries the ozone-mixed air stream. In some embodiments, the tubing may be a flexible hose made of any suitable material.



FIG. 3 is a diagram illustrating an example of the water treatment system 100 according to one embodiment. In this example, the water treatment system includes a water bucket 302, a removable lid 304, and a funnel 306 connected to the lid 304. The lid 304 may have an opening 305 that is sized to receive a narrow part 307 of the funnel 306. A water treatment device similar to the water treatment device 108 (not shown in FIG. 3) is fitted inside the bucket 302 and below the lid 304 for filtering and disinfecting water using ozone.



FIGS. 4 and 5 are drawings illustrating an example of a water treatment device 402 according to one embodiment. FIGS. 4 and 5 illustrate the lid 304 of FIG. 3 in an upside-down position to show the water treatment device 402 in a perspective view. The water treatment device 402 may be the same as the water treatment device 108 of FIG. 1. During operation, the lid 304 is installed onto the bucket 302 with the water treatment device 402 located inside the bucket 302. The water treatment device 402 includes a filtering element 404 that is configured to filter sediment, undesirable chemicals, biological contaminants, and/or suspended solids from the water that passes through the filtering element 404. In one embodiment, the filtering element 404 may be a pleated sediment filter or the like. The water treatment device 402 further includes an ozone distributor 406. In one embodiment, the ozone distributor 406 may be a highly porous tube that wraps around the filtering element 404 in a length direction. For example, the ozone distributor 406 (e.g., a highly porous tube) may be arranged in a helical or spiral shape wound around the filtering element 404. In operation, the ozone distributor 406 (e.g., a porous tube) receives a supply of ozone or ozone-mixed air from, for example, the ozone supply 200 via a pneumatically sealed hose or tube of any desired length and/or shape. The ozone distributor 406 is designed and shaped to diffuse an effective amount of ozone to disinfect the water filtered by the filter element 404. In some examples, the ozone distributor 406 can diffuse a large amount of ozone-mixed air bubbles into the filtered water in the water bucket 302 to achieve effective and efficient disinfection of the water using ozone. In one embodiment, the porous tube 406 is configured to provide a large porous surface to volume ratio such that a large amount of ozone-mixed air can be diffused into the water at a very high rate.


In some embodiments, the porous tube 406 when extended is substantially longer than the length and/or width of the water treatment device 402 or filter element 404. In this particular example, the porous tube 406 is coiled or wound around a substantial portion of the filter element 404. In other examples, the porous tube 406 may have other tortuous configurations like a wound shape, coiled shape, helical shape, bend shape, circular shape, rolled shape, spiral shape, and the like. By increasing the length of the porous tube 406 that can be wrapped around the filter element 404, a ratio of the surface area of the porous tube 406 to the volume of the filter element 404 can be increased. The porous tube 406 wraps around an exterior boundary of the filter element 404 two or more times. In some examples, the porous tube 406 wraps around the exterior boundary of the filter element 404 ten or more time. A majority of the porous tube 406 is proximate an exterior surface of the filter element 404. The configuration of the porous tube 406 and filter element 404 allow water to be filtered and ozonated concurrently or simultaneously.


While the above description contains many specific embodiments of the invention, these should not be construed as limitations on the scope of the invention, but rather as examples of specific embodiments thereof. Accordingly, the scope of the invention should be determined not by the embodiments illustrated, but by the appended claims and their equivalents.
