“…For instance, the prepared zirconia‐ceramic dual‐layer hollow fiber membrane (DLZK) prepared via a fast‐ and low‐cost technique, coextrusion phase inversion/cosintering, has shown great performance toward wastewater treatment due to its improved porosity and water flux (Figure 5b). [ 43 ] As shown in Figure 5c,d, the removal of TOC, COD, total nitrogen (TN), NH 3 ‐N, and total suspended solid in both textile industry (TI) and palm oil mill effluent (POME) wastewaters has increased by the enhancing cosintering temperature. In another research, dual and single‐layer hollow fiber membranes (DLZK and SLZK) consisting of zirconia and kaolin were modified into hydrophobic membranes by grafting process and their performance toward removing ammonia was assessed in membrane contactor application.…”
