Congratulations to PhD student Mohammed Alsubei (Ïã¸ÛÁùºÏ²ÊÖÐÌØÍø CEGE & NICE Group, CNIE) for his first publication in the ! The article reports on the significant achievement fabricating ceramic membranes for water treatment using natural and cost-effective materials. This work involves a highly productive collaboration of Mohammed Alsubei with Professor Luiza Campos (Ïã¸ÛÁùºÏ²ÊÖÐÌØÍø CEGE), (), Professor Marc-Olivier Coppens and Dr Barry Reid (Ïã¸ÛÁùºÏ²ÊÖÐÌØÍø Chemical Engineering).

In this study, ceramic membranes for water treatment were developed using a novel combination of white clay, silica flour, and either Arabic gum or marble powder. Two substrates, A and B, were formulated with optimal recipes determined by JMP software. Substrate A contained white clay (62.7 %), silica flour (32.3 %), and Arabic gum (5 %), while substrate B contained white clay (63 %), silica flour (26.8 %), and marble powder (10.2 %). The addition of waste glass in the coating layer enhanced separation efficiency, with substrate A (using coating CO-2) achieving a removal efficiency of approximately 99.2% for synthetic feedwater. Crossflow water fluxes were on the order of 100 L/m² h. Estimated costs for membranes A and B were approximately 51 and 47 USD/m², respectively, which is low, as no high sintering temperatures are required.
