Forward osmosis (FO) membrane processes have nowadays attracted many interests in water reuse applications due to its simplicity and low energy consumption. However, the osmotically driven water transport in through the membranes is much slower than theoretical value due to the concentration polarization effect in the polymeric support layer. Here, the formation, modification and optimization of porous support layers were performed to reduce internal concentration polarization effect by enhancing the water transport and salt passage in the polymeric support layer. The formation of more selective polyamide skin layers for FO membranes was also studied to reduce reverse salt flux in FO processes. |
