  • How do you make caustic soda?

The concentrated sodium hydroxide solution is further solidified to produce different forms of caustic soda, such as flakes or pearls.
  • How does SCB produce caustic soda & hydrochloric acid & sodium hypochlorite?
  • SCB has a modern plant for the production of caustic soda, hydrochloric acid and sodium hypochlorite based on a proprietary process the uses the most up-to-date membrane electrolysis technology.
  • How can a water treatment plant reduce corrosivity?
  • One way to reduce the corrosivity of the water is to increase the pH. This increase can be easily achieved at the treatment plant where chemicals and feed systems are already available for pH adjustment. For some waters, increasing the pH may lead to excessive precipitation of calcium carbonate.
