: : : : Need some help with a new dealkalizer unit. What kind of p-m/alkalinity numbers should i be getting?

: : : I have never operated a dealkalizer, but I would assume you are looking
: : : to get zero alkalinity out of the unit, and then blend that water with
: : : raw water to get your desired alkalinity numbers. Those desired alkalinity
: : : numbers will be chosen based on the process you are using the water for, in this
: : : case apparently a boiler. Vern
: : Yes, but the problem i have is really high chlorides and i'll get readings of say 8/p-alk and 8/m-alk and then the chlorides of 2000 or
: : higher. Shouldn't i be getting p-m/alk that are different like 20p and 45m with maybe lower chlorides? thanks.

: Bob, is this an ion exchange unit regenerated by salt? With a 2000 chloride level after regeneration,
: sounds to me like you aren't getting a good flush at the end of the cycle. I'm not certain what p and m alk readings
: you should be getting, but with ion exchange you should get close to zero until the resin bed becomes exhausted. I know
: a guy here in Fresno who works on these, I'll see if I can contact him and get some better info. Vern
Thank you, Thank you, Thank you. Bob
