Advanced 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) ...
متن کاملMicrobiological Study of a Bleached Kraft Pulp Mill Aerated Lagoon
Pulp mill aerated lagoons are subject to perturbations owing to the chang-ing composition of the effluent and variations in climate. Such stresses may affect microbial activity and the biodegradation of chlorinated organic compounds. Studies revealed thatvariation in the culturable microbial population in a northern Ontario kraft pulp mitl la-goon is related to process parameters (w...
متن کاملSystem Simulation Program for Kraft Pulp Mill Optimization
Recent work by Biegler (8) has investigated optimization techniques for sequential, modular flow sheet simulators. This work extends that effort. Successive linear programming coupled with a reduced gradient method gave fast, reliable optimization. A kraft pulping process involving 22 modules and 50 streams was optimized. Compared to the base case, significantly improved operating points were l...

متن کاملPreparation of Chitosan-Copper Nanoparticles Coated Kraft Paper, Characterization and its Antimicrobial Activity
In this paper, Chitosan-copper nanoparticles were successfully coated onto the Kraft paperusing a dip coating process. First, chitosan-copper nanoparticles solution was prepared byreduction method and the use of ultrasonic radiation. It was employed copper sulphate pentahydrateas precursor salt, NaOH as a reducing agent and Chitosan as capping agent to prepareChitosan-copper nanoparticles solut...
