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 کاملPresence of Hardwood Chips and Its Impact on Pulp Strength Properties in the Production of Bleached Softwood Kraft Pulp
The effect of hardwood admixture (15-25% birch or aspen) in kraft cooking on the strength properties of the fully bleached pulp was investigated. Results obtained from both laband mill-processed ECF bleached pulps showed that adding 15-25% birch or aspen to the production of fully bleached softwood kraft pulp had a minor effect on the strength properties. No significant effect was observed for ...
متن کاملCombined chemical biological treatment of bleached eucalypt kraft pulp mill effluent.
Effectiveness of ozonation before and after biological treatment for removal of recalcitrant organic matter in bleached kraft pulp effluents was compared. Two industrial ECF bleached eucalypt kraft pulp effluents (E1 and E2) were pretreated with 100 mg O3/L. Raw and pretreated effluents were treated biologically in bench-scale sequencing batch reactors, under constant conditions. Following biol...
متن کاملAcid hydrolysis of cellulosic fibres: Comparison of bleached kraft pulp, dissolving pulps and cotton textile cellulose.
The behaviour of different cellulosic fibres during acid hydrolysis has been investigated and the levelling-off degree of polymerisation (LODP) has been determined. The study included a bleached kraft pulp (both never-dried and once-dried) and two dissolving pulps (once-dried). Additionally, cotton cellulose from new cotton sheets and sheets discarded after long-time use was studied. Experiment...
