Abstract:

The research highlights on forward osmosis (FO) technology at the International Forward Osmosis Symposium (IFOS2016) in Sydney by the end of 2016 are summarized. For FO membrane materials, reduction in the structure parameter of the support layer, rather than the increase of the permeability of the active separation layer, is the key to improve the FO flux. Overall, the improvement in the rejection and antifouling properties is the key factor for high performance membrane. For draw solutes, inorganic salts appear to be the most promising candidates. Osmotic dilution and hybrid processes with other separation technologies for treating high salinity wastewater remain the main potential application. Unfortunately, in a short term, FO based salinity power generation is not competitive to other new energy alternatives.

Key words: forward osmosis, draw solution, osmotic dilution, structure parameter, highly saline wastewater, membranes, selectivity, separation

摘要：

回顾了2016年底在悉尼召开的国际正渗透研讨会的主要内容，概括了近年来正渗透技术研究和应用的最新进展。在膜材料方面，提高水通量应着重于降低支撑层结构参数，而不是提高分离层的渗透性能。提高分离层的截留率和耐污染性是提高膜性能的关键。对于各种类型的驱动溶质而言，无机盐很可能是最为现实可靠的驱动溶质。正渗透技术在渗透稀释和与其他分离技术的耦合过程处理高含盐污染水源中有潜在应用，然而渗透能发电在短期很难成为主流的新兴能源。
