HVAC USER !!! If you are using an arc and do not have a CO2 gas cover on your tank then you are generating very large quantities of silver nitrate.!!!!!!! I doubt you measurement of 30 -35 PPM. I have spend many hours and test runs on HVAC as Dr Bill Biagiolio and I were the developers of the process.
You cannot determine the PPM with a PWT as the product is highly acidic and the readings are useless. I can check for NO3 and NO as well as Ag+, with my spectrophotometer. If you don't have a CO2 gas cover then DO NOT drink it. "Ole Bob"
