Abstract

Scaling up from a laboratory batch process to a continuous manufacturing process can result in unexpected changes in membrane morphology and performance. To understand how processing effects the structure and performance of cellulose acetate filtration membranes, membranes were produced using laboratory-scale doctor blade and industrial/production-scale slot die casting. Differences in morphology were seen because of the different casting method. However, filtration performance using bovine albumin serum and lipase showed no significant differences.
