Electrokinetic Reactor for Heavy Metals removal from Industrial Wastewater Sludges : Design Aspects

The ill effects of heavy metals are well known and proved to be even cacogenic for human beings. The industries are the major source of heavy metal pollution and emits heavy metals by generating wastewater and sludge. Industrial sludges are the most concentrated heavy metallic waste and considered as hazardous one. Decontamination of such sludges is practiced in many ways, one of them is through Electrokinetic migration of heavy metals. However, the designing a reactor has to address numerous critical points such as voltage across, electrode material, current density, initial water content, space-time yield,reactor sizes, and serviceability of reactor. This paper covers all the design aspects of Electrokinetic reactor.
