Lesson 15 Nonfibrous additives and wet-end chemistry Retention of nonfibrous additives occurs through the mechanisms of filtration, chemical bonding, colloid phenomenon, and adsorption. Filtration is important for retaining only larger particles. The aluminum polymer has a significant flocculation effect ...
