  • How to remove hexavalent chromium from wastewater?
  • Removal of hexavalent chromium had attracted much attention as it is a hazardous contaminant. An electrocoagulation-like technology electro-reduction was applied. The chromium (VI) in the wastewater was reduced to chromium (III) by the electron supplied by electricity power and Fe 2+, formed from corrosion of steel electrodes in acidic conditions.
  • Can a nanoparticle remove hexavalent chromium from wastewater?
  • Passivation of nanoscale zerovalent iron hinders its efficiency in water treatment, and loading another catalytic metal has been found to improve the efficiency significantly. In this study, Cu/Fe bimetallic nanoparticles were prepared by liquid-phase chemical reduction for removal of hexavalent chromium (Cr (VI)) from wastewater.
  • How chromium is removed from wastewater?
  • Present work presents major experimental conditions influencing Cr removal and recovery from wastewater. Efficient nanomaterials on the basis of published publications have been found for effective chromium removal from wastewater. Adsorption techniques are seen to be preferable to other methods because they ecofriendly, and sustainable.
  • What is the final chromium disposal rate of industrial sewage treatment?
  • At HARBY TANNERY factory in Egypt, industrial sewage treatment achieved a final chromium disposal rate of 98.8% under optimized conditions. Wastewater treatment is no longer a mere option but an imperative necessity to safeguard the environment, ecosystems, and public health 1, 2, 3.
