What is Rejection Factor

Research into the wide possibilities of membrane-based applications is an interesting subject for the modern study of membrane science and technology. Membrane processes have been established as viable and recognized separation techniques in water and wastewater treatment processes. Membranes can be prepared into many forms, each with its intrinsic properties which ultimately determine its suitability for specific applications as well as the overall performance of the process. Thus, this chapter highlights the fundamental concepts of membranes and membrane processes. The critical parameters in membrane processes, and membranes' structural characteristics and parameters are reviewed.
