ABSTRACT: Water hardness, which can be defined as the concentration of calcium and magnesium ions, is known to vary greatly depending on geographical locations. Laboratory tests were carried out to evaluate effects of large differences in water hardness on the performance of certain wet-end additives to the paper machine process. Tests were carried out at hardness levels of 25, 125, and 225 ppm (as calcium carbonate equivalents). Increased water hardness was found to have a generally negative effect on the performance of a cationic acrylamide- type retention aid, although the extent of performance loss depended on experimental details. Likewise, rates of dewatering in systems containing cationic retention aid were adversely affected by increasing hardness, though the effects were not statistically significant in all cases considered. The tendency of bridge-forming flocculants (cationic retention aid or sequential addition of a cationic additive and then anionic retention aid) fell slightly with increasing water hardness.

Toward environmental resilience in pulp and paper manufacturing: Water consumption and carbon dioxide emission reductions, TAPPI Journal September 2025
ABSTRACT: Pulp and paper manufacturing is a water- and energy-intensive industrial sector, necessitating improvement of its operational efficiency, as well as reduction of emissions to the maximum extent possible. This review focuses on the reduction of water consumption and carbon dioxide (CO2) emissions that originate in the pulp and paper industry (PPI). First, process simulation and optimization techniques used for water consumption reduction are reviewed. Then, techno-economic analyses of solvent-based CO2 capture from PPI are discussed. Additionally, key actions are proposed for enhancing water consumption reduction and CO2 capture in PPI.
