Characteristics of Batch and Continuous Dynamic Membrane Dewatering Processes

Abstract

Characteristics of batch and continuous dynamic membrane dewatering processes were studied from a process designer's point of view. Gelatin concentration experiments on both botch and continuous processes were done with dual-layer dynamic membranes developed by the authors. The membrane itself was made from alumina sol and collodal silica.
Process simulations were carried out, using basic data obtained from a singlemodule experiment. Calculated values of flux, rejection and pressure head loss showed good agreement with experimental results from a complex system composed of modules arranged in series.
