Total Alkalinity vs. pH, and Their Roles in Water Chemistry

Oct 05, 2016 · Total alkalinity is measured by the amount, or concentration (ppm) in the water, not by how alkaline (pH) the water is. 'Alkalinity up' products are prevalent in the pool industry. If you are in the market for an alkalinity increaser, the two most common are sodium bicarbonate (NaHCO 3) and sodium carbonate (Na 2 CO 3), more commonly known as

ALKALINITY CONTROL - Guardian CSC

boiler water alkalinities rise above the recommended maximum, reduce the feed of alkali bearing materials or reduce the total alkalinity of the treated water if a softener is used. In an emergency, increase the blow down rate if necessary to bring boiler water alkalinity under control.

How to Lower Total Alkalinity and Adjust Ph in a Swimming Pool

Test your water source for alkalinity and use a different source if it has high TA because you'll need to use too much dry acid more often to lower both pH and TA in your swimming pool. Getting a perfect balance of pH and alkalinity is a little tricky since acid will lower both but not at the same rate.

Water Handbook - Preboiler & Industrial Boiler Corrosion

Maintenance of proper pH throughout the boiler feedwater, boiler, and condensate systems is essential for corrosion control. Most low-pressure boiler system operators monitor boiler water alkalinity because it correlates very closely with pH, while most feedwater, condensate, and high-pressure boiler water requires direct monitoring of pH.

extreamly high alkalinity and ph, soft water [Archive

whats going on here? My Total Alkalinity is WAY high, KH ppm 300+ PH-fresh water is way high 8.4 or higher But at the same time the GH, total (general) hardnes ppm is 0 to 25 (very soft)(i dont understand that) (on my pool), if the Alkalinity is high, I lower the PH to 7.0 and aeroate it to lower the alkalinity, and it also causes the pH to come back up.
