	<span style="line-height:1.5;">For treating wastewater, electrochemical engineering has been rediscovered during the last four decades through the world for its inherent advantages comparatively with traditional technologies especially the chemical and biological techniques. However, the expansion of this technology founded on electric current applying has been retarded by several technical-economic factors especially the detection of disinfection by-products (DBPs) formation. This work focuses on the challenges and future tendencies for this highly-efficient technology to reach the full-scale implementations particularly in disinfecting water. Lately, new versions of electrochemical techniques have been suggested such as employing sulfate radical anion (SO</span><sub>4</sub><sup>.-</sup><span style="line-height:1.5;">) and sunlight to generate </span><sup>.</sup><span style="line-height:1.5;">OH radicals in TiO2 photocatalysis and photo-Fenton water treatment. These improvements elevated the electrochemical engineering efficiency and acceptation. However, more efforts remain to be accomplished for water reuse vision. Future researches would focus on integrating membranes processes such as nanofiltration and reverse osmosis for a safe removal of DBPs.</span>
