摘要

"The slowdown of the white water through precipitation chemistry going on, and ultrafiltration in conjunction (lo - hardness ultrafiltration - LHU)".It is a white water treatment sector in the pulp and paper industries incorporated, which provides for the removal of hardness and total suspended solids in the effluent.Such removal is performed from the precipitation of calcium and magnesium ions, by adding sodium hydroxide, associated with an ultrafiltration system.The hardness and the total suspended solids are reused in the manufacturing process of the paper as raw material, and then the paper machine.The white water, after treatment is recycled in ideal conditions for its application in money as process water.
