Abstract: A method is described for making paper or paper board by applying a composition containing enzyme and cationic coagulant to papermaking pulp prior to paper forming to preferably improve drainage, retention, or both. Sheets of pulp from which paper or paperboard products are made with the method can exhibit excellent drainage, excellent retention of pulp fines, or both. The method also can be applied to other pulp treatments, such as waste water treatments. A system for making such treatments of paper furnish is also provided.
