Study of using water softening process byproduct, calcium carbonate on fine paper production

After water purification and softening, a lot of calcium carbonate with other impurities produce and these byproducts gather and bury as mineral sludge.In this research, The quality of calcium carbonate from water softening process in mazandran wood and paper industry (MWPI) mill and effects of load...
