Water Forcement WP PLUS is the common name for sodium carbonate, which has a molar mass of 105.9888 g/mol (anhydrous). Water Forcement WP PLUS 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.
Application
- Water ForcementWP PLUS 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 Water ForcementWP PLUS required to treat out the calcium can be approximated by 350 mg/L Calcium ions requires 1.0 kg/m³of Water Forcement WP PLUS.
- Water ForcementWP PLUS effectively and economically removes Calcium from anhydrite by precipitation as Calcium Carbonate.
- Over-treatment with Water Forcement WP PLUS can result in a Carbonate alkalinity and as consequent, excessive gel strength.
Advantages
- Widely available and economical source of carbonate ions to precipitate calcium while increase pH.
- Concentrate chemical: effectively removes calcium in most drilling fluids at small dosage.
- Effective flocculants for spud mud.
Recommended Treatment
Add Water Forcement WP PLUS in concentration of 1.0 - 3.0 kg/m³ to any system. Mix slowly through a jet mixer or sift slowly into the vortex of a high-speed stirrer.
