Marshall, Everybody, I'm still weighing the best approach to making the concentrated CS needed for our water purifiers, and your observations are presenting some new ideas. Specifically, perhaps I could up the CS content, ppm, by adding citric acid, lemon juice? Is this to do with the notion of allowing more silver cations by increasing the anions? Is citric acid better suited than others?
Concentrated CS used thus far in purifier saturation has been 27 volts at 200oF, in a double boiler, with polarity reversal every two minutes. We get beautiful, concentrated CS, but it takes many hours and the switching is a hassle. Also the water must be very low TDS so it's relatively expensive. By contrast another choice would be to use the maximum concentration allowable with a 110DC generator, the one we now use to get our everyday 10ppm CS. We can get upto about 30 liters per hour on one converter, which would be great for purifier saturation, at about 350 ml. per purifier. Perhaps this would work for us, cost effectively, if we were to use rain water. I'll check this with my Hanna PWT. Otherwise the distilled water we've been using would be too expensive, considering our goal is to minimize cost. The question would be whether we can substantially boost the CS content by adding citric acid. The last time I allowed the generator to surpass 20ppm I got a reading near 30 uS. I think it was Ode who told me I may actually have an equal amount of particulate silver, along with the ions, equivalent to about 60 ppm. If I could double this to about 120ppm, or even a little higher, the HVDC generator may be appropriate. Any ideas on numbers? Fortunately it's the monsoon here in South Asia, so sufficient rain water would not be a problem. Maybe we could do HVDC in the monsoon and 27 volts at 200F over time in the dry season.
