Magnesium Hydroxide Powder for Pulp Bleaching
Magnesium hydroxide can offer economic and process benefits in pulp bleaching. Cost savings from the reduction or elimination of certain bleach chemicals can be achieved by employing CellGuard®MH magnesium hydroxide powder as an alternative alkali and cellulose protector. Additional benefits such as a reduction in BOD/COD and anionic trash can improve wastewater treatment and papermaking operations downstream. CellGuard®MH, a high purity magnesium hydroxide powder, can be used as a cellulose protector in oxygen bleaching systems, as an alkali source in mechanical pulp peroxide bleaching and as a partial substitute for caustic soda in EOP and EP bleaching.
