초록

In pressure retarded osmosis (PRO) process, thin film composite (TFC) type membranes which can withstand high operating pressure are required. In this study, glass fibers (GF) are used as additive for mechanical strength enhancement of the support layer of TFC membranes. The support layers were fabricated by a phase inversion method by using the casting solution of blended GF (two different size of milled GF) with polyethersulfone (PES). The fabricated support layers were characterized by FE-SEM, FT-IR, contact angle goniometer, and universal testing machine. Lab-scale ultrafiltration experiment was carried out to measure their performance. As a result, the support layer with milled GF showed higher mechanical strength and water flux than the pure PES support layer, and the support layer with smaller size GF showed higher performance.
