Phosphoric Acid

1. pH Adjustment: Phosphoric acid can be used to lower the pH of water, making it more acidic. This is important because many water treatment processes work best within specific pH ranges.

2. Corrosion Control: Phosphoric acid forms a protective layer on metal surfaces, which helps prevent corrosion of pipes and other equipment in water systems

3. Scale Prevention: It can be used to prevent the formation of scale, which is a buildup of mineral deposits that can restrict water flow and reduce the efficiency of water treatment systems

4. Wastewater Treatment: In wastewater treatment, phosphoric acid can help remove pollutants and reduce bacterial growth.

5. Coagulation and Precipitation: Phosphoric acid can be used in coagulation and precipitation processes to remove impurities from water.

6. Phosphate-based chemicals: Phosphoric acid is a precursor for many phosphate-based chemicals used in water treatment, including orthophosphates and polyphosphates
