The purpose of adding acid is to adjust the equilibrium concentration of carbonate compounds by adjusting the pH value of water. And then adjust the equilibrium concentration of calcium carbonate to prevent the formation of calcium carbonate. 3. The common acids are hydrochloric acid and sulfuric acid.

Adding an alkali such as lime (calcium hydroxide) will therefore raise the pH from the acidic range (0 to 6) to the preferred, slightly alkaline range of 7 to 8 on the pH scale. Too much alkalinity — typically quantified in milligrams (mg) of calcium carbonate (CaCO3) equivalents per liter (l) of wastewater — and your pH will veer above your desired range.
