Removal of Pathogenic pollutants using electrocoagulation using aluminium electrodes

Abstract

Pathogenic contamination of fresh waste bodies is some of the most harmful types of water contamination where in aquatic environment the pathogenic microorganisms can reproduce, which may pollute the marine environment overall. In addition, there are serious side effects with microbial infection. Some many pasteurization processes, like membrane separation and additives, have therefore been used to remove microorganisms from wastewater. Most of these processes are inefficient or hazardous, like the chemical treatment. Lately, electrocoagulation process, due to the environmental safety and comparatively low operational costs, has paid considerable attention to remove pathogenic contamination of sewage treatment plant effluent. During this analysis, the consequences of the changing of the electrical current change from 0.5 to 1.5 mA/cm2 were examined on the ability of aluminium-based electrocoagulation unit for sewage treatment by disabling pathogenic pollutants. The findings demonstrated that the density of the current was increased to increasing the E. coli elimination (an indicator of pathogenic pollutants removal) to reach a current density of 2 mA/cm2 the strongest deactivation (83.2%). Rising the current density increases the bacterial removal. However, the increase in the current density increases the treatment cost.
