Alumina ceramic membranes are high-performance porous filtration materials manufactured by high-temperature sintering. Their asymmetric structure consists of a porous support layer, a transition layer, and a microporous separation layer, offering superior mechanical strength, chemical resistance, and long service life. Operating in crossflow filtration mode, tubular ceramic membranes efficiently separate suspended solids, colloids, macromolecules, and microorganisms from liquids, enabling high-efficiency filtration, purification, concentration, and resource recovery. With pore sizes ranging from microfiltration to ultrafiltration (≥2 nm), they are widely applied in industrial wastewater treatment, food and beverage processing, pharmaceuticals, biotechnology, chemicals, mining, and water recycling.
一、Definition
Alumina ceramic membrane is a precision ceramic filter material with porous structure fabricated by high-temperature sintering. It consists of three asymmetrically distributed layers: a porous support layer, a transition layer and a microporous membrane layer, with filtration ranges covering microfiltration, ultrafiltration and small pore sizes (≥2 nm).
Tubular ceramic membranes mostly adopt cross-flow filtration for fluid separation processes. The working principle is as follows: the feed liquid flows at high velocity inside the membrane tubes. Driven by pressure, the permeate containing small molecules penetrates the membrane outward perpendicularly through the membrane layers, while the retentate with macromolecular components is intercepted by the membrane. This achieves separation, purification and concentration of fluids.
