Crossflow microfiltration

Direct visual observation (DVO) was used to view membrane surfaces at different times in crossflow microfiltration of yeast suspensions with rapid backpulsing at varied backpulsing duration and pressure. The DVO photos show that the membranes are more effectively cleaned by longer backpulse duration

New mineral membranes made of sintered clay were performed and characterized in terms of porosity, hydraulic resistance, pore diameter and mechanical resistance. These membranes can be used as microfiltration membranes. The variations of the filtrate flux as a function of time are measured during cr

This presentation gives methods by which ultrafiltration and crossflow microfiltration system designs can be developed and optimized when data are available relating flux rate and membrane rejection to concentration and to other parameters. System layouts considered include batch, single-stage feed-
