The volume of water in your production cell is directly related to the time it will take to reach a particular ppm concentration of silver. I believe that a 3 second rate for polarity switching would make the process so inefficient that it would not work very well. Which, I believe, is your experience. My inquiries about switching times have always gotten the response that a 60 second switching rate is optimal. You may need some stirring as well... Dan

It seems too much long. I am using a 100mA transformer with a 30v DC supply & sheet electrodes of about 6 sq. ins on one side of one electrode. Naturally I use 2 electrodes of the same size. To emulate some of the manufacturers who are on the Internet I am using current control at 10mA & polarity change at 3 second intervals . Polarity exchange seems to have been the main cause of the time extension. Current control is based on about 0.8 mA per sq. inch of both sides of the one electrode. I am using polarity change because of the lack of sludge . Using distilled water as a starting point it can take up to 24 hours to reach this level. Using a starting solution of one litre, a quart, with the addition of 10% of a 10ppm ionic silver solution this time is cut down to about 12 hours. A clear solution is obtained & measured with a Hanna PWT meter. My feeling is that I must have made an incorrect assumption of one or more of the parameters so I would appreciate informed & practical advice. Direct access is at [email protected] & I am most happy to hear directly from anyone. Regards to you all. Julius Kabrun
