| Abstract | ||
| ..' . The application of an electri'c current was used to invest~gate the removal of heavy metals from a,dewatered wastewater municipal sludge. Electric current application enabled the removal of Nickel, Chromium, Zinc, and Coppe~ fiom sludge samples. Distilled water was introducid,to the electro-kihtic cell used for the study to compensate for cathodic effluent. As a conse&etice of electric current application, the amount of collected cathodic effluent,& fluctuations, and electrical conductivity variations of the cdllected catho'dic efhueit were investigated and found to be governing factofs for the application of the process. Approximately 40% of Nickel removal was achieved whileremoval of other investigatedmetals ranged from 5 to 8% 'during the experimental run. Removal rates of different metals and 'power consumption during the experimeinial run were also investigated. ' | ||
