: I'm a civil engineer looking into a high pH (alitlle above 10, but high enough to cause problems with the county)problem. I've been told that the boiler room may be generating it. I've read a lot on this site about acidic problems with sulfite, but haven't read anything about high pH problems. Does anyone have any experiences with this? Thanks.
Tara, Our employer guidelines and Betz Dearborn guidelines are to maintain a pH between 10.5 and 11.5 in our low pressure steam boilers. If the pH drops below this level we add more liquid caustic to the chemical batch tank to elevate the pH level in the boiler.
