I work at a water bottling plant and I'm just trying to figure out how to test our mineral solutions. I'd appreciate it if anyone can help me with this one.One blend of water uses a sodium sulfate/sodium bicarbonate solution which is injected in RO water at a rate of .75ml per 1 gallon. The mineral solution is made of 96 gallons RO water, 30.72 lbs sodium sulfate and 50 lbs sodium bicarbonate. TDS on RO averages approx 0.8 ppm and the desired TDS on finished product is 12 - 18 ppm. What should the TDS on the mineral solution be to give me the desired result on finished product.
