Bioremediation of organic contaminated soils*
The term bioremediation covers a wide variety of engineered systems which utilize microorganisms to degrade, detoxify and immobilize organic contaminants. These systems include: l solid-phase treatment using unlined iand treatment systems or prepared bed bioreactors, l slurry-phase treatment systems completed either in-place or within tanks or impoundments, and l in situ treatment systems. Bior...
متن کاملBioremediation of Uranium Contaminated Soils and Wastes
Contamination of soils, water, and sediments by radionuclides and toxic metals from uranium mill tailings, nuclear fuel manufacturing and nuclear weapons production is a major concern. Studies of the mechanisms of biotransformation of uranium and toxic metals under various microbial process conditions has resulted in the development of two treatment processes: (i) stabilization of uranium and t...

متن کاملBioremediation 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 کاملReduction of AOX in the bleach plant of a pulp mill.
The reconfiguration of an existing five-stage bleaching D0E1D1E2D2 sequence is proposed to ensure the minimal formation of organochlorine compounds, expressed as AOX, in the bleach plant of a kraft pulp mill processing Eucalyptus globulus wood. This reduction of the load of AOX in the effluents can be achieved without introducing new and expensive technologies in the bleaching process. In pract...
