Old regular "old, old standard" ballast (ca 1940) should work fine. The lamp was described a a preheat type, was it not. Working ballasts for such lamps are a bit hard to find now. OP lamps have a different glass that transmits the ozone producing line. Germicidal lamps do not normally pass this line for safety reasons. -- JosephKK Gegen dummheit kampfen die Gotter Selbst, vergebens. --Schiller

Wow, it was about 20 years ago that i provided professional input to a decision to use ozone or chloramines in such a plant. -- JosephKK Gegen dummheit kampfen die Gotter Selbst, vergebens. --Schiller

Moreover the long lasting toxicity of chloramines and long term exposure problems are starting to be documented. -- JosephKK Gegen dummheit kampfen die Gotter Selbst, vergebens. --Schiller

I use pure distilled water in a silver electrolysis process. Sometimes there are problems that appear to be due to something in the water, and changing vendors often helps. The conductance of different vendor's products measured with a Hanna Pure Water Tester can range from 0.6uS to 1.2uS. So there is nothing obvious in the measurement that points to something in the water, but it sure doesn't work very well. Do you have more information on problems with chloramines, particularly how to detect their presence, what effects they may have on an elctrolysis process, and how to remove them from the water? Thanks! Regards, Mike Monett

At most gas stations they seem to try to sell you de-ionized. |
