Water has been an inevitable part of human life and its civilization, and water contamination is caused by pollution from industrial wastes such as effluents, dyes, and heavy metals and sewage water due to human activities. Therefore, cost-effective treatment of wastewater has to be carried out without giving any by-products. This chapter is aimed at explaining the different ways of electrochemically treating the wastewater and degrading the contaminants. Electrochemical treatment is advantageous over other methods as it is inexpensive and is a green technique. The mechanism of degradation through anodic oxidation has been explained in details. The incorporation of microorganisms toward water treatment and using them for different kinds of sensors to detect the contaminants opens a new window to address this issue. Along with microorganisms, nanomaterials and ionic liquids are also used in sensing the pollutants and in removing and converting them into energy as well.
