Calcium salts are precipitated by the addition of sodium carbonate. Ca2+(aq) + CO3 2–(aq) CaCO3(s) Magnesium salts are precipitated by the addition of sodium hydroxide. Mg2+(aq) + 2OH–(aq) Mg(OH)2(s) A flocculant is added (this causes suspended particles to clump together and fall out of solution) and the precipitates are skimmed off the brine.
• Service flow rate: 3-6 gpm/sq. ft. but may be modified to adapt to local conditions Calcite is a naturally occurring calcium carbonate media. One of the advantages of Calcite is its self-limiting property. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions.
