Slaked lime for water storage

Lime for storage water

When added to water, hydrated lime dissolves and releases hydroxide ions (OH-). These ions react with hydrogen ions (H+) present in acidic water, neutralizing the acidity and raising the pH level. By neutralizing acidic water, lime makes it less corrosive and more suitable for consumption and industrial use.

Hydrated Lime Treatment In Drinking Water

Hydrated lime is frequently used in water treatment in three areas:

Prior to coagulation to increase the pH and alkalinity of the water to bring them to optimum levels for coagulation
To absorb aggressive carbon dioxide from some groundwater
As a final pH, alkalinity and calcium ion level adjustment before water is delivered to the consumer to reduce corrosivity (or aggressiveness or plumbosolvency)
