| Abstract |
Discarded polymeric or ceramic membranes are currentlyin needof appropriate and sustainable management. In the present study, thedirect reuse of discarded ceramic membranes in membrane contactor(MC) systems for CO2 removal was investigated for the firsttime. The hydrophobic surface modification of the discarded ceramicmembrane was done by using macromolecule additive coating. The influenceof operational parameters (absorbent liquid flow rate (Q (L)), feed gas flow rate (Q (g)), and different NaOH concentrations) of the MC on CO2 removal was investigated to prove the technical feasibility of reusedceramic membranes. The CO2 absorption flux was 7.9 x10(-4) mol/m(2) s at optimal conditions of2 M NaOH, Q (L) (20 mL/min), and Q (g) (300 mL/min) with a removal efficiency of98%, which lasted for 8 h. This study demonstrates a potential alternativefor the reuse of discarded ceramic membranes and avoids their disposalin landfills. The proposed approach will also bring membrane technologyinto the circular economy and achieve sustainability goals by reducingthe amount of waste from discarded ceramic membranes in the futureand combating global warming by absorbing CO2. |
