Hello folks, were doing soem trouble shooting on out ORP system and would like some feed back on those who use one for disenfection what in your eyes is an acceptable or normal amout of variance in ORP reads on the dechlor end. Example if you knew a set point of 150 would give acceptable dechlor results and thats what your set point is how far above and below that mark do you see in a typical 24 hour peroid. Here were getting typically + - 30 MV either way when its running good but have seen swings of 100 MV above our set point which isnt acceptable for permit maintaining results. Set the value significantly lower and we overdose with Bisulfite and the result is poor B.O.D. results due to 02 depletion from excess S02.
Thank You for any feed back you can offer.

What are the SO2 mg/l values you are seeing at the different ORP values?
