Soda Ash
pH Control Agent
Product Description
Soda Ash (Na2CO3) is the common name for sodium carbonate, which has a molar mass of 105.9888 g/mol (anhydrous).

Soda ash is inexpensive and used as an economical method for removing soluble calcium. Magnesium is similarly precipitated as insoluble magnesium carbonate; however, a more effective treatment for magnesium hardness is caustic soda, which precipitates magnesium hydroxide.
  • Soda Ash is used to precipitate Calcium in make-up water or while drilling anhydrite stringers.
  • Provided the saturation level of the Calcium salt has not been exceeded, the amount of Soda Ash required to treat out the calcium can be approximated by 350 mg/L Calcium ions requires 1.0 kg/m³ of Soda Ash.
  • Soda Ash effectively and economically removes Calcium from anhydrite by precipitation as Calcium Carbonate. Over-treatment with Soda Ash can result in a Carbonate alkalinity and as consequent, excessive gel strength.
