First of all, Great Site!

I'm new to the water treatment.
We are a small company that services a rural area, we purchase our water from the city next to us. We put a water tower in line about 7 months ago and it was going good. We also implemented a sanitation station, where we are introducing chorine in gas form, and amonia sulfate. We are curently injecting at a 3:1 ratio set at 9 lbs chlorine : 4.9 amonia. we are injecting both ways into the tower and outgoing. We are haveing a hard time maintaining our chlorine in the tower and out going. I checked the ph in the water in tower and got a 7.2.

We seem to be loosing our chlorine level during peak usage.

Any Help or Comments.

We have the dosage set up to one value, it doesn't change. We have tried to up the value and still no change.

Another thing, we have the means to check our chlorimines, but don't know what values to look for, what numbers are good or what we compare it to. I did some researsh and found that at a 3:1 ratio and a ph of 7.2 we should have our monochlorimines form in 0.22 seconds. But didn't help or see any diffreance.
