Kraft pulp mill effluent treated by activated sludge and aerated lagoon genotoxicity assess
Organic compounds present in the bleached kraft pulp mill (BKPM) effluents may be reduced by biological treatment like: activated sludge (AS) or aerated lagoon (AL). However, after biological treatment, BKPM effluent still contains specific compounds. Some of them have been related with chronic effects (DNA damage, reproductive and physiological) observed on fishes exposed to BKPM effluents. Th...
متن کاملBiological activity of bleached kraft pulp mill effluents before and after activated sludge and ozone treatments.
Eucalyptus bleached kraft pulp production, an important sector of the Brazilian national economy, is responsible for generating large volume, high pollutant load effluents, containing a considerable fraction of recalcitrant organic matter. The objectives of this study were to quantify the biological activity of the effluent from a eucalyptus bleached kraft pulp mill, characterize the nature of ...
متن کاملA multi-criteria decision analysis of management alternatives for anaerobically digested kraft pulp mill sludge
The Multi-Criteria Decision Analysis (MCDA) procedure was used to compare waste management options for kraft pulp mill sludge following its anaerobic digestion. Anaerobic digestion of sludge is advantageous because it produces biogas that may be used to generate electricity, heat and biofuels. However, adequate management of the digested sludge is essential. Landfill disposal is a non-sustainab...
متن کاملIntegrated Production Planning and Route Scheduling in Pulp Mill Industry
In this paper we consider the complete supply chain for a large pulp producer in Sweden. The supply chain is divided up in two parts, the pulp production planning problem and the distribution to customers problem. We focus on the overall problem and the interaction between the partial problems and discuss how to solve these simultaneously in a supply chain logistic support system. We have model...
متن کاملAdvanced oxidation of bleached eucalypt kraft pulp mill effluent.
In this study a poorly biodegradable (BOD/COD = 0.3) industrial alkaline ECF bleaching filtrate was treated using different advanced oxidation processes to evaluate their use in combined chemical-biological treatment aimed at increasing recalcitrant COD removal and improving final effluent quality. Oxidative treatments included ozonation combined with hydrogen peroxide (2, 5, 10, 20 mmol L(-1) ...
