Membrane distillation (MD) has emerged as a next generation of desalination technique to resolve the limitation of RO process. In this study, Polybenzoxazoles(PBO) membrane via thermally rearrangement of polyimide containing hydroxyl groups was prepared [1]. The effect of operating conditions such as feed temperature, Reynolds number of feed flow and salt concentration of feed were investigated. TR polymer membranes were characterized by SEM, AFM and contact angle. Thermally rearranged polymers showed a potential to MD process with advantages of high flux and long-term stability during operation.
