Abstract Scope |
Composites made from porous materials have the advantage of tunable pore size distributions, which can determine the overall permeability. This study focuses on low-cost micro/ultra-filtration membranes made with natural zeolite (clinoptilolite) particles (<45 microns) in a ceramic geopolymer matrix. Previously, the effect of additive on the pore size distribution and the permeability were presented. In this study, we highlight the development of environmentally sustainable thin ceramic filtration membranes with three zeolite-geopolymer composites (with 0, 10 & 20 vol% additive) coated on perforated aluminum or steel scaffolds to improve mechanical integrity and cured under pressure at 60 °C. The adhesion of the composites on these scaffolds was evaluated with micro-CT and SEM. The pore properties of the final products were primarily analyzed with mercury intrusion. Results from continuous crossflow water filtration studies will be presented to highlight the membrane performance. |
