My two cents worth (actually, Bruce K. Stenulson's two cents worth) pulled from... http://web.idirect.com/~showcase/althealth/makecs.htm
In an AC powered operation as some others are promoting, where the polarity is constantly switched, other undesirable things may happen; it is known that in all electro-colloidal silver generating processes, some charge stripping of silver ions does occur as they come in contact with the cathode, resulting in their gaining electrons, and the resulting reduction to atomic silver particles (without the charge that is said to produce the pathogen disabling effect.) 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. [To summarize this for the technically inclined] please consider carefully that, just as positively charged silver ions are generated into the system at the anode, they are attracted to the negatively charged cathode. Many stay in the colloidal suspension, but as the concentration of silver ions build up, and the current flow through the system increases, more and more silver ions are drawn to, and come in contact with the cathode. When they do this, they are stripped of their positive charge, and 'plate out' on the surface of the cathode as a visible 'sludge', but do not bond to the surface structure - they accumulate as larger groups of loosely bonded, uncharged silver particles. If what I understand Dr. Becker and others to be saying is true, these uncharged silver particles, what I refer to as the 'silver sludge' formed at the cathode, should be removed if possible from your finished product. Using a DC power source, with no polarity reversal, is my strong recommendation (and that of many others) for predictably generating positively charged colloidal silver particles (biologically active silver ions) in your product, while controlling silver 'sludge' dispersal problems. [Note that this DC supply can be produced either from an AC source, rectified, regulated, and filtered, or from a battery supply.] Electroplaters have long known that a well rectified DC power source was required to generate and manipulate metallic ions in their processes to achieve the desired results.
