Electroviscous Effects in Ceramic Nanofiltration Membranes
ChemPhysChem, 2015AbstractMembrane permeability and salt rejection of a γ‐alumina nanofiltration membrane were studied and modeled for different salt solutions. Salt rejection was predicted by using the Donnan‐steric pore model, in which the extended Nernst–Planck equation was applied to predict ion transport through the pores.

Membrane module can be understood as a physical unit, which gathers all the elements that participate in the separation process. Membrane module is, basically, composed by membranes, channels where feed goes through, the permeate and concentrate, and by pressure or current support structures applied to the system.

Hafnia ceramic nanofiltration membranes
Journal of Membrane Science, 2000Abstract We use the hindered transport theory for neutral solutes and the macroscopic homogeneous electro-transport theory for ions to predict without any adjustable parameters the limiting rejection of, respectively, four neutral molecules and five binary electrolytes by granular porous hafnia nanofilters.

Synthesis of ceramic membranes
Journal of Materials Science, 1992Non-supported γ-alumina films are prepared from a boehmite colloidal suspension. After calcination at 600°C, the microstructure is characterized by a mean pore diameter of 3 nm, a porosity of 50% and a tortuosity of 5.5. The structure is formed by card packed, plate-shaped particles, giving rise to slit-shaped pores.

Porous ceramic membranes for membrane reactors
2013This chapter discusses the research and development of porous ceramic membranes and their application as membrane reactors (MRs) for both gas and liquid phase reaction and separation. The most commonly used preparation techniques for the synthesis of porous ceramic membranes are introduced first followed by a discussion of the various techniques used ...
