ABSTRACT: Chemical water treatment problems such as disinfection by-products (DBPs) generation have urged on the search for better water treatment technologies such as electrochemical water technologies that have been applied successfully in different water/wastewater pollutants removal. However, their large expansion is hindered by similar DBPs troubles. Throughout the electrochemical process, such carcinogenic substances can be produced depending on the electrode material and applied voltage. This work aims to discuss recent advances recorded in dealing with DBPs formation in electrochemical devices. Numerous sophisticated techniques are lately suggested such as an interesting method employing carbon felt cathodes in which DBPs are less formed, and another judicious method utilizing boron-doped diamond anodes in which perchlorate production is decreased. Many action plans for removing halides from water to reduce DBPs are also listed. Combining electrochemical processes and their merging with nanotechnologies for better efficiency in dealing with pathogens and DBPs removal are suggested. Secure multi-barrier techniques, like distillation, granular activated carbon, and membrane processes have proven their excellent effectiveness in eliminating pathogens and pollutants. Employing those invincible technologies, thanks to their relatively low costs and ease of applications, is an encouraging domain of research with a perspective to bypass the DBPs formation during the efficient electrochemical processes.
