High calcium ,hydrated lime, is one of the most effective reagents for ,acid neutralization, and pH adjustment. These characteristics along with the presence of calcium assists in the removal of a wide variety of contaminants from water to improve the quality and keep customers and the environment safe. ,Hydrated lime, releases very little exothermic heat when in contact with water …

Neutralization, experiments ,with hydrated lime,, calcium hydroxide, Ca(OH) 2 This set of experiments that uses calcium hydroxide as the neutralizing base has the results given in Table 6 . Compared to raw ,lime, or ,lime, stone, the amount of Ca(OH) 2 needed to reach the same state of ,neutralization, is high (13.3 to 28.2 g for 1 cu m of Plant water to reach pH of 5.0, 6.4 and 7.1, …
