Irrigation 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 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 کاملPollutants from Effluent Streams
There are a variety of approaches to removing gaseous pollutants from effluent streams: absorption, adsorption, condensation, chemical reaction, incineration, and selective diffusion through a membrane. Absorption is an operation involving mass transfer of a soluble vapor component to a solvent liquid in a device that promotes intimate contact between the gas and the liquid. The driving force f...
متن کاملHeadspace Gas Chromatographic Method for the Determination of Hydrogen Peroxide Residues in Bleaching Effluent
A simple, rapid, accurate, and practical headspace gas chromatographic method is proposed for the determination of hydrogen peroxide residues in bleaching effluent. This method is based on the reaction of hydrogen peroxide with ceric sulfate, under acidic conditions, where hydrogen peroxide is converted to oxygen, which is then measured using headspace gas chromatography (HS-GC) coupled with a ...
متن کاملEffluent Loads From Different ECF Bleaching Sequences Used In Hardwood Kraft Pulp Bleaching
Effluent loads from different traditional and emerging ECF bleaching sequences were investigated. Oxygen delignified Eucalyptus camaldulensis and Acacia mangium kraft pulps having similar kappa number, ca 12.0 were used in this study. Different ECF bleaching sequences were compared with reference sequence, D0EopD1 in terms of effluent load, such as AOX, COD and TOC. Depending on the nature of s...
