Lime in Pulp and Paper Mills Graymont

Lime is used in several applications within pulp mills. One of the most common applications is for the sulfite-pulping process. This process uses acid to dissolve the glue (lignin) that holds the fibers (cellulose) together. When acidic water discharged from this process is neutralized, lime is the reagent of choice in order to safely elevate the pH of the effluent stream prior to discharge
