Evaluation of Solar Powered Pool Purification Device

Prior to installation of the FLOATRON device the pool was requiring
approximately 10 gallons of liquid chlorine each week during the summer months
to maintain adequate chlorine levels (5.0 ppm). Approximately half this amount
was required during winter months. Approximately 0.5 gallons per week of
muriatic acid was also required to maintain proper pH with the extensive amount
of chlorine added. The pool was pumped an average of six hours per day in
summer and three hours per day in winter. Sweeping and vacuuming is
performed once per week. Although one gallon of algicide was added each
month, the pool had chronic problems with black algae which accumulated on the
shaded south side of the marcite surfaces. This problem was very difficult to
combat, further increasing chlorine and algicide requirements as well as vigorous
brushing with a stainless steel brush for removal.
Once installed, the FLOATRON device was able to Increase the copper ion level
to 0.2 ppm within a period of two weeks of use. Initially, the copper level was
checked frequently to determine when to float or remove the device. However,
based on experience, the principal Investigator has found that floating the unit
every other week creates the required Ion level without constant measurement.
As recommended, the chlorine levels were slowly reduced such that
approximately one quart of chlorine is now added each week. This trace level is
maintained to provide oxidation necessary to provide proper pool clarity. It should
be noted, however, that the user was once away for a month long trip where the
FLOATRON was floated, but no chlorine was added. Upon return, no algae
growth was in evidence and after pool cleaning and addition of trace chlorine, the
pool was once again sparkling clear.
Since the FLOATRON has been used, the user's problem with black algae has
disappeared. Furthermore, at no time, since the device has been used has there
been any evidence of algae growth. The amount of time required for pool
maintenance has been greatly reduced (as well as the necessary trips to procure
pool chemicals). The operation of the unit has been entirely satisfactory.
4. SUMMARY OF RESULTS
The following conclusions can be drawn from our evaluation:
The FLOATRON device is very effective at eliminating algae. The test pool
required a once a month introduction of algicide to stop growth on the east wall
prior to the introduction of the device. Within ten days of the Introduction of the
FLOATRON device to the pool the algae was eliminated and did not recur during
the test period.
The FLOATRON device begins producing ions immediately after being placed in
a pool when exposed to sunlight, and will produce ion levels sufficient for pool
