SODA ASH
SODA ASH is the common name for Sodium Carbonate (Na2CO3). SODA ASH is used primarily to remove calcium from make-up water and to treat calcium contamination, mainly from drilling anhydrite.
Application
SODA ASH is used to increase alkalinity and control pH. SODA ASH is used to remove calcium ions from solution. Keeping a low calcium level will increase the hydration rate of bentonite and polymers. Sodium levels should be limited to the requirements described in ERCB D-50 salinity requirements (EC-SAR).
Advantages
- Effectively removes calcium ions
- Increases the alkalinity and reduces calcium hardness, therefore
- increasing the yield of bentonite and many polymers
