Bioremediation of paper and pulp mill effluents.
Pulp and paper mill effluents pollute water, air and soil, causing a major threat to the environment. Several methods have been attempted by various researchers throughout the world for the removal of colour from pulp and paper mill effluents. The biological colour removal process uses several classes of microorganisms--bacteria, algae and fungi--to degrade the polymeric lignin derived chromoph...
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 کاملAcetylene reduction (nitrogen fixation) by pulp and paper mill effluents and by Klebsiella isolated from effluents and environmental situations.
High rates of acetylene (C(2)H(2)) reduction (nitrogenase activity) were observed in woodroom effluent from a neutral sulfite semi-chemical mill under aerobic (up to 644 nmol of C(2)H(4) produced per ml per h) and under anaerobic (up to 135 nmol of C(2)H(4) produced per ml per h) conditions. Pasteurized effluent developed C(2)H(2) reduction activity when incubated under anaerobic but not under ...
متن کاملActivated Sludge Treatment of Paper Mill Effluents
Introduction The pulp and paper industry is the second largest industrial water consumer in Europe with a usage of 35 m3/ton paper and a production of 85.2 M tons/year. Its effluents cause considerable damage to the receiving waters if discharged untreated since they have a high biochemical oxygen demand (BOD), chemical oxygen demand (COD) and contain chlorinated compounds, suspended solids (ma...
