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

Alkalinity is water's capacity to resist acidic changes in pH, essentially alkalinity is water's ability to neutralize acid. A water body with a high level of alkalinity (which is different than an alkaline water body) has higher levels of calcium carbonate, CaCO3, which can decrease the water's acidity.

Alkalinity - an overview | ScienceDirect Topics

Alkalinity,, pH, and total inorganic carbon combine to control and define the carbonate balance and which form of carbonate is present. As stated previously, ,alkalinity, is the ability for water to ,neutralize acid, and is the sum of the concentrations of carbonate (CO32− ), bicarbonate (HCO 3− ), and ,hydroxide, (OH −) ( Hill and Giani, 2011 ).
