Lime in the Pulp and Paper Industry

Lime is an important ingredient in the manufacture of pulp and paper. It is used in the treatment of liquid wastes as a coagulant in color removal, a filtration conditioner and as a neutralizing agent. It is also used in the recovery of valuable by-products from pulp and paper mill wastes.
