Funny you should ask! Sometimes there’s just no accounting for what’s going on with a pH system. We had a recent application, for example, where it was necessary to split a single wastewater stream and use two identical pH treatment systems. One of the systems worked well right from the start. The treated water pH of the second stream surged up and down, kept turning its pump on and off, and couldn’t be controlled within its limits. Why? The same wastewater, identical treatment systems — things like this are supposed to work the same, aren’t they? Not necessarily. We tried a number of solutions, including programming changes for the pump response, and a new electrode. That didn’t do it. Eventually, we added some additional mixing and re-positioned the branch electrode, ultimately getting a comparable response to that of the first treatment system. The problem was in the hydraulics.
Theory applies only in general to your specific pH system. We try to design a system so that it can be easily maintained, and so that the components can be adjusted or re-arranged to optimize their performance. Help us by answering some questions about your particular application (see Basic pH System Questions), and we’ll put together the most economical pH treatment package for you that we can. Then we’ll help you to make it work.
