Abstract
A method is provided for treating brine recovered from a coal seam gas operation. The process entails directing brine recovered from a coal seam gas operation to a mixed reactor and mixing an alkaline earth reagent with the brine. This results in the precipitation of alkaline earth salts and silica, which form alkaline earth salt crystals having silica adsorbed thereto. Thereafter, the alkaline earth salt crystals and adsorbed silica are directed to an evaporator that produces a concentrate having the alkaline earth salt crystals and adsorbed silica.
