ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present disclosure relates to a water treatment kit, and, more specifically, to a swimming pool water treatment kit which enhances and/or replaces conventional chlorine treatment.
2. Description of the Related Art
Chlorine has been used for the treatment of water in swimming pools for many years. Chlorine is commonly sold in either a powder form or a tablet form and is dissolved in water to prevent the growth of algae and to kill bacteria.
However, the use of chlorine to treat water in swimming pools has been known to have disadvantages. For example, the chlorine tablets commonly used to treat water in swimming pools are known to cause the pH of the water in the pool to fluctuate drastically. Fluctuations between a pH level of 3 to 11 are not uncommon. Not only is the chlorine less effective at the these extremes in pH, the acidic water also irritates the eyes and other sensitive areas of persons swimming in the pool. In order to adjust the pH level to a neutral pH, additional chemicals must be added to the water to raise or lower the pH accordingly.
Another disadvantage of chlorine is that it must be added to the water on a daily basis to maintain the proper concentration. When the chlorine is first introduced into the water, the chlorine concentration is high and the bacteria and algae is effectively eliminated. However, as the chlorine concentration drops off and/or when more persons swim in the water, the bacteria and algae is not eliminated as effectively.
Thus, a need exists for a water treatment system which provides an alternative to chlorine while still providing an effective means for continuously treating swimming pool water and killing algae.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a safe, odorless, less expensive, and effective alternative to the conventional use of chlorine to treat water, particularly swimming pool water.
It is a further object of the present invention to provide a water treatment system in the form of a kit which incorporates the essential materials needed to effectively treat swimming pool water.
It is yet a further object of the present invention to provide said kit having the appropriate treatment means to maintain a swimming pool for approximately one season, e.g., ninety (90) days.
In one embodiment of the present invention a water treatment kit includes a package; a housing stored within the package, the housing having a first water treatment chemical therein and a plurality of holes defined in an outer wall portion thereof for dispensing the first water treatment chemical into water; and at least one chemical dosage stored within the package independent of the housing, the chemical dosage comprising a second water treatment chemical; the first water treatment chemical of the housing and the second water treatment chemical of the chemical dosage being dispensed within the water at respective controlled rates to treat the water. The first water treatment chemical includes copper sulfate and a copper ionizable grid and the chemical dosage includes sodium or potassium monopersulfate. The package includes a handle formed in an upper portion thereof to facilitate easy handling of the kit, and two molded half sections which are joined by a living hinge.
A method of treating water is also disclosed including the steps of placing a container, having a plurality of holes formed therein, into water; continuously dispensing copper sulfate pentahydrate through the plurality of holes formed in the container into the water; and placing at least one water treatment tablet formed of monopersulfate into the water at a rate of about one tablet every two weeks. The method of treating water may also include the step of cleaning the water in the pool prior to the step of placing the container into the water.
These and other objects, features and advantages of the present invention will become apparent from the following detailed description of illustrative embodiments, which is to be read in connection with the accompanying drawings.
