Did some testing today with some recently purchased chemicals at work.
My boiler water. DO 4.73ppm. pH 6.78
1 gram of sodium sulfite to 1 litre boiler water; DO < .5 ppm. pH 9.92
Did not add an sodium hydroxide but thought I would have to. My boiler water tested @ pH 8.92 IIRC last year and now it is down to pH 6.78. I have never added any treatment to my water.
Half this conc. did nothing, so I think I will stick with this conc. 3.875 L = 1 gal. so.. 3.875L x 1300 gal = 5037.5L / 454 = 11.09 lbs of sodium sulfite.
And maybe I will have to add sodium hydroxide in the future to keep the solution caustic @ pH 8-10
Does this seem right? I know that boiler treatments have alot more additives but I think this is the most abundant and crucial for an open system, DO and pH.
Please, any and all comment welcome.
