Investigate the effect of anionic trash management through removal and neutralization of dissolved and colloidal substances (DCS) On properties of CMP pulp and paper

During the paper manufacturing process, especially when mechanical pulp or recycled pulp used, a large amount of soluble and colloidal substances (DCS) are comprised and dispersed or dissolved in the process water. Accumulation of DCS during the papermaking operation with the increasing closure proc...
