PAPER MAKING PROCESSES AND SYSTEM USING ENZYME AND CATIONIC COAGULANT COMBINATION
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...

| description | 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.
Se describe un método para fabricar papel o cartón al aplicar una composición que contiene enzima y coagulante catiónico a la pulpa de fabricación de papel antes de la formación de papel para mejorar de preferencia el drenaje, retención o ambos. Las hojas de pulpa de las cuales se hacen los productos de papel o cartón con el método pueden exhibir excelente drenaje, excelente retención de finos de pulpa, o ambos. El método también se puede aplicar a otros tratamientos de pulpa, tales como tratamientos de agua residual. También se proporciona un sistema para hacer tales tratamientos de la pasta de papel. |
