In this work, the effect of clay nanoparticles as a casting solution additive on the morphology and performance of polyethersulfone ultrafiltration membranes was evaluated. Ultrapure water permeability was used to initially survey membrane performance and the membranes cast with 1% clay+1% sodium he...
