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 ...

Effect of ozonation on activated sludge from pulp and paper industry

Aerobic biological treatment with activated sludge is the predominant process all over the world for treatment of pulp and paper industry wastewater. 50–70% of the biodegradable organic material is oxidized to CO2 and the rest is converted to bacterial biomass, typically termed as excess sludge or waste activated sludge (WAS). Handling and disposal of WAS in general and in particular from the ...

Modeling of the fouling of inside-out hollow fiber UF membranes

Membrane processes often experience a decline in the permeate flux or an increase in the operating pressure from membrane fouling. A mathematical model that describes the fouling of inside-out hollow fiber ultrafiltration (UF) membranes was derived from hydrodynamic equations coupled with the theory of depth filtration. The correlation predictions obtained in this study are simpler, as the ...

Dynamic perspective on the relation between environmental policy and eco-efficiency: the case of wastewater treatment, waste and energy efficiency in the Dutch paper and board industry

The relation between environmental policy and innovation is complex. This paper aims to gain insight into the way accumulation of policy measures, or in other words, the increase of policy pressure, affects research activities and eco-efficiency. Three environmental domains have been researched for the Dutch paper and board industry: wastewater, waste and energy. Three trends (19802003) are ...
