Biosorption of hexavalent chromium in a tannery industry wastewater using fungi species
The isolated fungi species of different kinds from chromium contaminated soil sites located in Nagalkeni, Chennai were used for reducing chromium(VI) in a tannery industry wastewater of Nagalkeni, Chennai. The experiments were conducted to know biosorption potential of isolated fungi species for removing chromium(VI) in a tannery industry wastewater against the different pH, fungi biomass and ...
متن کاملCharacteristics of a novel Acinetobacter sp. and its kinetics in hexavalent chromium bioreduction.
Cr-B2, a Gram-negative hexavalent chromium [Cr(VI)] reducing bacteria, was isolated from the aerator water of an activated sludge process in the wastewater treatment facility of a dye and pigment based chemical industry. Cr- B2 exhibited a resistance for 1,100 mg/l Cr(VI) and, similarly, resistance against other heavy metal ions such as Ni2+ (800 mg/l), Cu2+ (600 mg/l), Pb2+ (1,100 mg/l), Cd2+ ...
متن کاملExperimental Study on the Factors Affecting Hexavalent Chromium Bioreduction by Bacillus cereus
Chromium through natural processes and human activities enters the air, soil and water. Chromium-resistant bacteria are capable of reducing toxic Cr(VI) to less toxic Cr(III). In this work, batch studies were conducted to evaluate the effect of environmental factors on the rate of Cr(VI) reduction from synthetic wastewater of metal plating industry by Bacillus cereus under aerobic conditions. T...
متن کاملHexavalent chromium removal in a tannery industry wastewater using rice husk silica
Present study dealt the removal of Cr(VI) in a tannery industry wastewater using rice husk silica powder as an adsorbent.The experimental investigations have been carried out by using rice husk silica powder for different adsorption dosage, different contact time and different pH against the initial Cr(VI) concentration of 292 mg/L. The maximum percentage removal of Cr(VI) in the tannery indust...
متن کاملPhytoremediation Enhanced with Concurrent Microbial Plant Growth Promotion and Hexavalent Chromium Bioreduction
Contamination of agriculturally arable land with industry derived pollutants including heavy metals such as chromium has affected soil fertility as well plant, animal and human health by indirectly entering the food chain. Hexavalent chromium is a byproduct of tanning, electroplating, wood, dye, paper, glass, ceramic etc. industries and is usually discharged as industrial effluent. Cr (VI) is a...
