How do you treat high alkalinity in water?
How do you treat high alkalinity in water?

Alkalinity ,can, be defined as the ability of a water to neutralize ,acid, or to absorb hydrogen ions. It is the sum of all ,acid, neutralizing bases in the water. This ability to maintain the proper pH in the ,wastewater, as it undergoes treatment is the reason why alkalinity is so important to the ,wastewater, industry.

Not all odors in ,wastewater, are from H2S, and there is no correlation between H2S and other odors. The total H2S procedure is good up to 18 mg/1, and higher concentrations must be diluted before testing. H2S production ,can, be controlled by up-sewer aeration which reduces US formation and also stabilizes the ,wastewater, in the collection svstem. 14-104

Why does aeration tank increase pH?
Why does aeration tank increase pH?

You ,can, then add ,acid, to lower both pH and TA with the net effect of lowering only the TA. Then aerate until the pH rises to 7.4 to 7.6. Similarly, how does nitrification affect pH? During nitrification, 7.14 mg of alkalinity as CaCO 3 is destroyed for every milligram of ammonium ions oxidized. Lack of ,carbonate, alkalinity will stop nitrification.
