With increasing concerns of organic micropollutants, which are not removed by conventional wastewater treatment process, advanced oxidation processes (AOPs) are recently introduced. Among AOPs, electrochemical advanced oxidation processes (EAOPs) have advantages of simple operation and reasonable costs for construction and maintenance. However, low diffusion rate of pollutants from solution to electrode is regarded as a limitation. In this study, hollow fiber type of carbon nanotube (CHF) was fabricated and operated with flow through system to enhance mass transfer rate. The removal efficiency of BPA was achieved in following order: flow through, cross-flow, and batch methods. In addition, rate of removal in flow through system was significantly enhanced, comparing that of cross-flow operation.
