Caustic soda is widely used in the treatment of water. In sewage treatment stations, caustic soda allows the neutralisation of the effluent and a reduction in the hardness of the water. In the industry, caustic soda achieves the regeneration of ion exchange resins.
Caustic soda is a very strong base, having relatively high solubility in water. Thanks to caustic soda’s liquid form, measurement of the amount to be used is greatly simplified in a large number of applications in the water treatment field.
Caustic soda is currently used in water treatment with various objectives:
- elimination of the hardness of the water
- regulation of the water’s pH
- neutralisation of effluent before the water is discharged
- regeneration of ion exchange resins
- elimination of heavy metal ions by precipitation.
