Abstract
The main aim of this chapter is to conduct a simple literature review on treatment wastewaters from pharmaceutical and related industries and establish efficacies of electrochemical treatment technique in removing selected pollutants form raw wastewater. Synthetic (simulated) wastewaters were prepared using standard methods. Fractional factorial (2K - P -1) experiments were utilized at random to determine influence of selected factors (separation distance between the electrodes, volume of the wastewater used, applied current, temperature of the wastewater, treatment time, concentration of the pollutant, concentration calcium of hypochrite (Ca(OCl)2) added and depth of the electrode into the wastewater used) on efficiency of electrochemical process in removing Biochemical Oxygen Demand concentration at five (BOD5). Industrial wastewaters were collected from industrial sources within the country (Nigeria). The industrial wastewaters collected were subjected to electrochemical treatment and chemical treatments individually and in combinations under specified treatment conditions.
