Alkalinity - Wikipedia
Alkalinity - Wikipedia

Alkalinity, (from Arabic "al-qalī") is the capacity of water to resist acidification. It should not be confused with basicity which is an absolute measurement on the pH scale.. Alkanity is the strength of a buffer solution composed of weak acids and their conjugate bases.It is measured by titrating the solution with an acid such as HCl until its pH changes abruptly, or it reaches a known ...

To neutralize the highly acidic wastewater from a cation resin regeneration, a supply of alkaline liquid is needed. An anion resin regeneration is usually performed at the same time, and its wastewater is alkaline. When these two wastewater streams are combined, the pH is “neutralized” and approaches 7. If the resulting pH of the

A base (or alkali) substance is one that will accept protons, thereby neutralizing the acid. An example of an alkali is hydroxyl (OH-), which when combined with the acidic hydronium ion (H3O+) neutralizes, forming two molecules of water: OH- + H3O+ → 2H2O. Raw wastewater generally has a pH near neutral (7.0), although it may vary between 6 and 8.
