Sulfuric acid (H₂SO₄) is a highly corrosive and versatile chemical used in many industries, including water treatment. It is a strong acid and an important industrial chemical due to its wide range of applications.
Properties:
- Formula: H₂SO₄
- Molar Mass: 98.079 g/mol
- Concentrated Form: Usually 98% sulfuric acid by mass in industrial applications.
- Highly exothermic when diluted with water (releases heat).
Applications in Water Treatment:
1. pH Adjustment:
- Sulfuric acid is used to lower the pH of water in both drinking water and wastewater treatment processes.
- It neutralizes alkaline water, making it less corrosive and more suitable for industrial processes.
2. Scaling Prevention:
- By reducing the pH, sulfuric acid can help prevent the formation of scale (calcium and magnesium deposits) in water systems.
3. Ion Exchange Regeneration:
- Sulfuric acid is used to regenerate cation exchange resins in water softening systems, replacing calcium and magnesium ions with hydrogen ions.
4. Phosphate Precipitation:
- In wastewater treatment, sulfuric acid helps to precipitate phosphates, which can then be removed from the water.
5. Alkalinity Control:
- Sulfuric acid is used to reduce alkalinity, which is critical in maintaining the proper chemical balance in water treatment systems.
