Predicting Calcium Carbonate Scaling processheating.com

Jan 11, 2019 · Predicting calcium carbonate scale in water systems has been done for more than 20 years — often with questionable or even inaccurate results rather than actual field observations. Perhaps the oldest method is the marble test[1], a crude, qualitative test used primarily for potable water rather than cooling water. The marble test method led to the development of a more quantitative method by
