Microbiological 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 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) ...
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 کاملIrrigation of eucalyptus plantation using treated bleached kraft pulp mill effluent.
The use of treated pulp mill effluent on eucalyptus plantation appears to be an attractive option for plant nutrition and water supply. It also constitutes a supplementary treatment process and a final disposal option for the mill effluent. This study aimed at the investigation and evaluation of the effects of bleached kraft pulp mill treated effluent on three typical Brazilian soils used for e...
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 ...
