Abstract

Abstract: Ozone and hydroxyl radicals ( OH) are powerful reactive oxidizing species (ROS) that are commonly utilized in water disinfection. The electrochemical advanced oxidation process (EAOP) is often used to generate such oxidants, whereas optimizing its experimental setup and electrode parameters plays a crucial role in its performance. This research aims to find the optimal setup for ROS generation process from tap water via the boron‐doped diamond. The effect of electrode's active area, type of electrode substrates (mesh or sheet), type of mesh substrate (rolled and unrolled), and number of anodes and cathodes are examined. The results showed that the use of two long‐rolled BDD/Nb meshes as anode and one long‐rolled mesh as a cathode gives the optimal performance of electrolysis process at 15 V potential and 3 min. These results will provide a start for developing a cost accepted, health‐safe, household disinfection device that reduces susceptibility to human life‐threatening waterborne diseases. Practitioner Points: This research aims to find the optimal setup for ROS generation process from tap water via the boron‐doped diamond. The effect of electrode's parameters on the electro‐production of ROS is examined. The best performance is achieved using rolled mesh electrodes. Two long‐rolled BDD/Nb meshes as anode electrodes and one long‐rolled mesh cathode electrode give the optimal electrolysis process performance. Abstract : The best performance of ROS generation process from tap water via the boron‐doped diamond is achieved using long‐rolled mesh electrodes with two anodes and one cathode.
