medium, and 12 percent coarse, the particle fineness of the material is calculated as: Fineness = (66 x 1) + (22 x 0.4) + (12 x 0.1) = 76 percent Effective calcium carbonate equivalent (ECCE) is the measure of the effectiveness of liming materials and is calcu - lated as the product of the purity value (CCE) and the fineness value divided by 100

Control of Calcium Carbonate Scale Formation by KDF®

1. Dissolution of zinc ions from the medium blocks calm carbonate growth steps and induces aragonite precipitation. This in effect means that calcium carbonate scale formation in the system stops and any existing scale is removed. 2. An increase in the pH of the water, caused by the production of hydroxyl ions, lowers the carbon dioxide
