Enzymatic Removal of Phenol from Industrial Wastewaters

Removal of surfactant from industrial wastewaters by coagulation flocculation process

Surfactants are among the most widely disseminated xenobiotics that contribute significantly to the pollution profile of sewage and wastewaters of all kinds. Among the currently employed chemical unit processes in the treatment of wastewaters, coagulation-flocculation has received considerable attention for yielding high pollutant removal efficiency. Jar-test experiments are employed in order t...

Removal of pharmaceuticals from industrial wastewaters by microalgae culture

Enzymatic approach to phenol removal from wastewater using peroxidases

Introduction Phenol and its derivatives are present in various industrial effluents and possess a high level of toxicity even at minute concentrations. This could cause serious ecological problems if phenol-containing effluents are discharged untreated or partially treated into water bodies or land sites. Method Conventional wastewater phenol removal methods, which include biological treatment,...

Removal of high concentrations of nitrate from industrial wastewaters by bacteria.

Klebsiella oxytoca isolate 15 was isolated from the grounds of a nitration factory and was found to be tolerant to nitrate at concentrations up to 0.5 to 1 M. Physicochemical parameters for optimal growth conditions for K. oxytoca isolate 15 were established. Growth took place when the nitrate concentration in the medium was less than 150 mM, and full nitrate consumption required about 14 g of ...

Evaluation of Recent Treatment Techniques for Removal of Heavy Metals from Industrial Wastewaters

Removal of heavy metals from industrial wastewaters can be accomplished through various treatment options, including such unit operations as chemical precipitation, coagulation, complexation, activated carbon adsorption, ion exchange, solvent extraction, foam flotation, electrodeposition, cementation, and membrane operations. This paper describes these various treatment strategies and methodolo...
