Tom & list, A method you might want to experiment with is to used pulsed DC, rather than constant current DC; I've been running my CS generator with a ~20KHz pulsed square wave, ~55% duty cycly, at 15VDC, using 1/4 of the previous batch as a 'starter' added into pure distilled water; with water pre-heated, an 8 oz. batch runs to 20PPM on the TDS1 in around 35-40 minutes. (At this 15 volt operating level, A current of 8mA, as read on a digital multi-meter wired in series, is my cutoff point, yielding about the same ~20PPM TDS1 reading every time.) "Bridging' of the "sludge" does not occur; the buildup on the negative electrode (cathode) stays clinging to the negative electrode fairly well; (it helps to have the negative electrode with twice the surface area of the positive silver electrode, so hydrogen gas bubble evolution does not dislodge & redisperse the sludge into the water...) My impression is that the particle size produced is fairly fine, (based on the light refraction characteristics) but I haven't had the financial resources to have the particle size analyzed by an independent lab... I personally prefer to make a fresh 8 oz batch when I get down to the 1/4 level, thereby always having a fairly fresh supply on hand. A subject for testing is to store a batch for several months, then use it in comparison to a fresh batch of the same PPM in side-by-side testing in something like the "milk test" being discussed recently on this list. This should give a better idea of the "shelf life" of the home brew CS we're making. On the subject of storage, I would expect that filling a container to eliminate virtually all air before long term storage would eliminate reaction with the air as a cause for CS deterioration. And while some makers of "Super CS" claim they can leave their product sitting out in direct sunlight without affecting it's ability to disrupt pathogens, I'd like to see this demonstrated in the 'biological inhibition' tests before I 'swallow' that claim.<grin> I'll keep mine out of the light.
