7. Water Treatment:
- Caustic soda is used for pH adjustment in water treatment processes, including drinking water and wastewater treatment.
- It can also be used for water softening, helping to remove hardness-causing minerals from water.
8. Food Processing:
- Caustic soda is used in food processing for cleaning and sanitizing equipment and facilities, especially in dairy and beverage industries.
9. Cleaning and Degreasing:
- It is used as a powerful degreaser and cleaner for various industrial equipment and surfaces.
Due to its highly corrosive and caustic nature, caustic soda lye should be handled with extreme care. Personal protective equipment (PPE) such as gloves, goggles, and protective clothing should be worn when working with it. Proper ventilation and handling procedures are essential to avoid accidents and injuries.
Caustic soda lye should be stored in a cool, dry, and well-ventilated area, away from incompatible materials (acids, metals, etc.). It should be stored in containers made of materials that are resistant to its corrosive effects, such as high-density polyethylene (HDPE) or glass.
