Understanding a component of industrial papermaking and its pollution load through the application of multivariate analysis
A multivariate analysis technique was used to characterise the interrelationships between the input variables involved in industrial papermaking in order to predict the corresponding wastewater load. The root causes of increasing water pollution load were found to be associated with reprocessing of paper products, pulp stock composition, and inconsistent chemistry for coating operations and paper formation. For Duplex Coated Board (DP) production, the relationships between material input factors and wastewater loads were found applicable for more predictive environmental management.
