Prospects and Challenges of Electrooxidation and Related Technologies for the Removal of Pollutants from Contaminated Water and Soils

Electrooxidation as an alternative decentralizedDecentralization wastewater treatment technique has been considerably investigated to develop different remediation and disinfection solutions of diverse classes of wastewater and soil washingSoil washing effluents. It is a clean technology with distinguished advantages such as high versatility, amenability, limited chemical addition and ease of operation at ambient temperature and pressure. This technology is highly efficient, and it has been established as a powerful decontamination technique for depolluting different classes of contaminated wastewater and soil washingSoil washing effluents. In this chapter, the prospects, and challenges of electrooxidation and related processes applied to wastewater and contaminated soil treatmentSoil treatment were summarized. The recent advances in anode materials applied in electrooxidation, the different anode designs and configurations were examined. Principles and mechanisms of electrooxidation coupled with other processes such as UV, ultrasonic irradiation and sulfate radical-based AOPs to accelerate and enhance pollutants mineralization, their advantages and limitations over electrooxidation alone were enumerated. Applications of electrooxidation and related processes as decentralizeDecentralization and point-of-use clean water technology, electrochemical disinfection and soil washingSoil washing/flushing effluents treatment were discussed. The challenges and limitations of electrooxidation and related processes critically reviewed.
