| Outline of Final Research Achievements |
Forward osmosis (FO) membrane system has gained significant research attentions in wastewater treatment, especially targeting to zero liquid discharge (ZLD). In this research, we have developed a FO system as well as organic solvent resistance FO membrane in order to treat a wastewater including partial organic solvents. The results are as follows: 1) We successfully developed organic solvent resistant FO membrane; 2) We got a precise knowledge about types of partial organic solvent and their concentrations which influenced the active layer performance of the prepared FO membrane. We also confirmed that the support layer was not influenced by any conditions; 3) Usage of the prepared organic solvent resistant FO membranes under optimum operating condition enabled to concentrate the wastewater up to 50 wt% of the partial organic solvent.
