Electrochemical Treatment of Water as an Effective and Emerging Technology

Abstract

Environmental pollution has been a major problem worldwide. This makes environmental pollution control an important ingredient to a healthy environment. During the last few years, water has become an increasingly important issue in developing nations. Progress in health and education is dependent on access to affordable sanitation and safe water. This chapter as a further study of the authors' previous studies presents a review of articles on designs, models, and applications of electrochemical processes with particular attention to the removal of environmental pollutants (conventional and emerging pollutants). The study revealed that electrical treatment processes can be in the form of electrochemical, electrocoagulation, electrophoresis, electro-flotation, electro-precipitation, electro-adsorption, and electrooxidation. It was concluded that electro-driven technologies can be used in many applications; electrochemical technologies have been proven to be quite useful approaches regarding wastewater treatment, and power sources of electrochemical can be wind and solar photovoltaic.
