Chemco - Soda Ash Systems - Brochure

Sodium Carbonate (Na2CO3), usually known as Soda Ash, is commonly used in water treatment to increase the pH of acidic water.  Soda ash systems are employed to act as first a pH adjuster with the added benefit of softening of the water.  Soda ash systems are typically used as a point-of-entry injection system.  Corrosion-resistant chemical feed pumps will discharge the soda ash solution into the water to raise the pH.  Alternatively, the solution can be delivered by gravity by utilizing an overflow weir and trough to deliver the soda ash solution to the point of application.
