ABSTRACT:
A method for inhibiting the formation, deposition, and adherency of scale-forming salts, including calcium sulfite, in process waters. The method is particularly suited for use in pulp mill lime kiln flue gas scrubber systems and multi-effect evaporators. Additionally, the method is effective at high pH and high calcium sulfite saturation levels.
