Recovery of organic substances dissolved in mechanical pulp

摘要: This invention relates to a method for the recovery of organic substances dissolved or brought into colloid form during manufacture mechanical pulp where said has not been subject previous alkaline bleaching other process carried out under conditions. The is characterized in deacetylation galactoglucomannans having colloidal pulping process, and subsequent deposition deacetylated glucomannans onto solid phase, such as fibers inorganic additives. performed either by alkali enzymatically. diminishes substance loading on recycling waters effluents, improves yield strength properties pulp.
