Abstract

The aim of the present work was to evaluate the removal efficiency of several contaminants from power plant wastewater. It included biochemical oxygen demand (BOD), chemical oxygen demand (COD), turbidity, total iron, total dissolved solids (TDS) and total suspended solids (TSS) and others by using electrochemical coagulation technique. Samples were collected from power station wastewater by electrochemical treatment (EC) using laboratory scale electrochemical cell to remove some of contaminants.  Results obtained showed that the optimum conditions were pH = 8, 12 volts and 0.8 amp.  The maximum removal of contaminants such as (TSS) was 94.6 % at 10 minutes, while for BOD it reached 54.2% at 14 minutes. The percentage removal of COD reached 72.3% at 12 minutes. In regard to total iron, the maximum removal reached 88.6 % at 16 minutes.
