In a DC system, these reduced metallic particles remain as a grayish 'sludge' buildup on the surface of the cathode, and eventually are very visible at higher current levels. In a system where the polarity is switched constantly, this sludge is propelled and dispersed back into the water continuously, as evidenced by the 'clean electrodes' spoken of.
Mechanical effects of redispersal of plated out silver "sludge" from the cathode will occur at higher concentrations and especially at higher currents, especially if AC is used, resulting in much coarser, uncharged metallic silver particles than may be desired floating about in your product. Filtering with good lab quality filter media may be able to remove some of this "non-ionic" silver; settling of most of the really larger particle "clumps" might also occur within 72 hours, I'd estimate, if the particles are not too fine. I guess the question is this; are the positively charged colloidal silver ions, (as produced in a DC process), what you want in your product, or do you want non-charged 'non-ionic' metallic silver particles, as produced in the AC processes? From what I have researched and what I understand at this time, I'd stay with Dr. Becker's recommendations myself, and try to produce the positively charged Colloidal Silver Ions with a DC process. James: The statement above could be taken as a working hypothesis. Your next step is to produce data which support this argument. Since HVAC CS is stable over time (this is, there's no sludge to drop out so where's the sludge), the weight of the evidence, so far, does NOT support this hypothesis. -- The silver-list is a moderated forum for discussion of colloidal silver.
