Characterization of the Properties of Inorganic Membrane Materials

1. Chemical Stability Inorganic membranes exhibit excellent chemical stability and can operate over a broad pH range. Their chemical stability is primarily determined by the properties of the membrane material, such as its crystal structure and chemical bonding. For example, α‑Al₂O₃ membranes demonstrate superior stability compared to γ‑Al₂O₃ membranes. Additionally, the chemical stability of porous membranes is influenced by their pore size and specific surface area.

The “dual” effects of ceramic membranes in the fields of biopharmaceutical concentration and wastewater treatment

Ceramic membrane separation is a size‑exclusion process that relies on pore size, employing a dynamic cross‑flow filtration mode: the feed liquid is circulated at high velocity through the ceramic membrane pores by a recirculation pump. Under pressure, the clarified permeate passes through the ceramic membrane and the porous ceramic support, permeating perpendicularly outward, while the retentate is retained by the membrane and flows rapidly within the channels, generating turbulence that continuously flushes the inner surface of the membrane, carrying away any trace deposits adhering to the membrane and maintaining a steady effluent of clarified liquid, thereby achieving separation, concentration, and purification of the fluid.
