Uses of citric acid in water treatment
pH adjustment: Citric acid is a mild acid used to lower pH levels in water. This balance water to improve the efficiency of other treatment chemicals or for preventing scale buildup.
Scale & mineral removal: It is an effective cleaning agent for removing hard water deposits, lime scale, and other mineral stains .
Membrane cleaning: In industrial applications, citric acid is used to clean membrane filters in water and wastewater treatment facilities.
Water softening: Citric acid acts as a chelating agent, meaning it binds to metal ions like calcium and magnesium in hard water. This process softens the water without adding sodium to the water, which is beneficial for drinking.
Iron removal: Citric acid removes iron contaminants from water softeners, maintaining their efficiency and lifespan.
