Product Specification
| High Light | Zirconia tubular ceramic membrane ，Alumina-supported ZrO₂ membrane ，High-precision crossflow filtration membrane | ||
The Zirconia Tubular Ceramic Membrane features a high-purity zirconia (ZrO₂) separation layer supported by a robust alumina (Al₂O₃) porous substrate. This asymmetric multi-layer structure combines the exceptional separation performance of zirconia with the excellent mechanical strength of alumina, providing reliable filtration under demanding industrial conditions.
Manufactured through precision coating and high-temperature sintering, the membrane delivers a highly uniform pore structure with outstanding chemical resistance, thermal stability, and long-term durability. It is ideal for nanofiltration, ultrafiltration, clarification, concentration, and purification processes requiring high product purity and consistent performance.
The membrane consists of three functional layers:
This asymmetric design optimizes both permeate flux and filtration accuracy while maintaining structural integrity during continuous operation.
The membrane operates using inside-out crossflow filtration.
Feed liquid enters the internal channels of the tubular membrane. Under transmembrane pressure, water and low-molecular-weight substances permeate through the zirconia separation layer, while suspended solids, bacteria, proteins, colloids, nanoparticles, and other larger components are retained inside the membrane channels.
The continuous crossflow velocity effectively minimizes membrane fouling and maintains stable permeate flux during long-term operation.

The zirconia separation layer provides an extremely narrow pore size distribution, enabling efficient removal of bacteria, proteins, colloids, nanoparticles, and other fine contaminants while maintaining high permeate quality.
The porous alumina support offers excellent compressive strength and structural stability, allowing the membrane to withstand high operating pressures and repeated cleaning cycles.
The zirconia membrane surface maintains excellent resistance to strong acids, alkalis, oxidizing agents, and many organic solvents, making it suitable for aggressive process environments.
The dense and smooth zirconia surface minimizes contaminant adhesion and biofilm formation, extending filtration cycles and reducing cleaning frequency.
The inorganic ceramic construction allows repeated chemical cleaning, high-pressure backwashing, and thermal sterilization without significant degradation, resulting in lower lifecycle costs than polymer membranes.
Customized dimensions are available according to specific process requirements.
Compatible housing materials include:
Available pressure ratings:
Supports complete filtration skid integration with online CIP cleaning and high-pressure backwashing systems.
