Description
  • The influence of particle size and zeta-potential of the feed particles (TiO2) and a membrane surface (alfa-Al2O3) with changes of pH on permeate flux during microfiltration using a tubular ceramic membrane have been studied. The properties of alumina tubular membranes and the aqueous titania dispersions were measured and related to the filtration characteristics. The experimental system is also described. It was found that permeate flux was dependent on the surface charge of the suspended particles and to some extent dependent on the surface charge of the membrane. This phenomenon was especially pronounced during microfiltration of dispersion around its isoelectric point, when permeate flux increased significantly.

  • Byl studován vliv velikosti částic a zeta-potenciálu částic disperze (TiO2) i povrchu membrány (alfa-Al2O3) na intenzitu toku permeátu při změnách pH. Pro mikrofiltraci byly použity trubkové keramické membrány. Bylo zjištěno, že hodnota intenzity toku permeátu je závislá na povrchovém náboji suspendovaných částic a částečně i na povrchovém náboji membrány. Tento jev je nejvíce patrný při mikrofiltraci disperze v okolí izoelektrického bodu, kdy hodnota intenzity toku permeátu výrazně vzroste. (cs)
