Phenol is a major pollutant in wastewater. It has severe effects on human beings, in both the short term and long term. Various methods were used for removal of the phenol from wastewater such as adsorption, photodecomposition, activated carbon, Fenton process, electrocoagulation, and so on. Electrochemical treatment seemed to be a promising treatment method due to its higher effectiveness, lower cost, and so on. In order to remove the phenolic compounds in water, pulsed electrolysis method was used in this work. The possibility of using pulsed electrolysis with alternative current power (AC Power) to remove phenolic compounds from wastewater is researched by using the Ti/PbO2 electrode. The removal rate of phenolic compounds is investigated in terms of various parameters, such as electrolysis time, voltage, frequency, and the flow rate. The energy consumption is also analyzed. Results show that the electrolysis method has optimal conditions by using the Ti/PbO2 electrode according to the energy consumption results.
