초록

Forward osmosis (FO) is an emerging technology to produce clean water with low energy consumption. The key elements in FO are a water-permeable membrane, and a draw solution inducing an osmotic pressure difference across the membrane. A desirable draw solution should result in a high osmotic pressure difference,together with an internal concentration polarization as low as possible.The draw solution should also have a very low toxicity,particularlywhen usedin drinking water purification. Furthermore, it is important to be easily recovered from a feed solution after FO operation for a certain period time. The multiple requirements make it difficult to develop an effective draw solution. In the present study, thermally and pH-sensitive oligomeric mixtures are used as potential draw solutions for FO system.
