Wastewater treatment plants and residential areas are closely located in residential region developed by urbanization. Therefore, complaints of wastewater treatment plants near local residents have been increasing continuously. So, this study is related to an ion cluster application device for removing the complex odors from wastewater treatment plants. It was designed that mechanical framework based on electrochemical property and applied to the work site in which to properly generate a

... rmal. Therefore, it was studied that making the ion clusters suitable in wastewater treatment plants, and handling the main malodorous/ substances occurring ions generated by using the ion clusters. To handle the major malodorous substances that occur in wastewater treatment plants a dielectric barrier discharge was adopted by utilizing such characteristics using is one of the principles of non-thermal plasma in this study. In this research, the main goal of is compared batch type and continuous type. And then, we are going to find the method by applying the appropriate method in the process of removing a variety of malodorous substances.
