Alumina ceramic membrane support

In high-end industrial fields such as biopharmaceuticals, food and beverages, microelectronics and chemicals, precision filtration is a core link to ensure the purity, safety and quality of products. As the key supporting component of the filter membrane element – the alumina ceramic membrane support, its performance directly determines the efficiency and stability of the entire filtration system.

Core product advantage: Why does the alumina ceramic membrane support have outstanding performance?
Alumina ceramic membrane supports are made from high-purity alumina raw materials through precise forming and high-temperature sintering, and possess a series of irreplaceable excellent properties:

1. Outstanding mechanical strength and rigidity: With extremely high compressive strength and hardness, it can withstand extremely high transmembrane pressure differences and system pressure fluctuations, effectively preventing membrane elements from deforming or being damaged under high pressure, ensuring stable filtration accuracy.
2. Excellent thermal stability: It can withstand temperatures up to 1600℃, is suitable for high-temperature sterilization processes (such as SIP, online sterilization), and can endure repeated high-temperature – cooling cycles without performance degradation, ensuring a long service life.
3. Excellent chemical inertness: It has outstanding resistance to strong acids, strong alkalis and organic solvents, and hardly reacts with process media, eliminating the risk of product contamination and ensuring the purity of the filtrate.
4. Precise pore size and uniform pore structure: Through advanced forming and sintering technologies, a precise structure with extremely narrow pore size distribution and high porosity can be achieved, providing uniform and stable flow channel support for the filter membrane and reducing filtration resistance.
5. Excellent wear resistance: With a high surface hardness, it can resist the erosion of solid particles and demonstrates an extremely long service life in the filtration of liquid materials with a high solid content.

Which key problems should be solved?
The selection of alumina ceramic membrane supports aims to address the pain points of traditional support materials (such as plastic, metal or common ceramics) under harsh working conditions:
Solving pollution problems: Replacing rust-prone metals and plastic supports with easily soluble substances fundamentally eliminates ion precipitation and impurity introduction, meeting strict regulations such as GMP and FDA.
Solving the problem of short lifespan: In high-temperature and highly corrosive environments, plastic parts are prone to aging and deformation, while metal parts are prone to corrosion and perforation. In contrast, alumina ceramics almost never age, significantly reducing the comprehensive usage cost of the equipment.
Solve reliability issues: Prevent membrane element failure, filtration accuracy decline or even system shutdown caused by deformation or rupture of the support under high pressure, and ensure the continuity and stability of production.
Adapt to harsh processes: It provides a reliable hardware foundation for special processes such as high-temperature sterilization, filtration of highly corrosive liquid materials, and production of high-purity products.

Wide application fields
Alumina ceramic membrane supports are the preferred core components for high-end filtration equipment in the following industries:
Biopharmaceuticals: Sterilization filtration, ultrafiltration and microfiltration systems for vaccines, antibodies and blood products.
Food and beverages: Clarification and sterilization filtration of fruit juice, alcoholic beverages, and dairy products.
Microelectronics and Semiconductors: Preparation of ultrapure water, filtration of chemical mechanical polishing (CMP) slurry.
Chemical Engineering and Petrochemical Industry: Catalyst recovery, filtration of strong acid and strong alkali solvents, purification of process gases.

Real customer cases (anonymous）
Case Background: In a well-known domestic biotech company, during the ultrafiltration step of its monoclonal antibody production, the stainless steel membrane support was frequently corroded by chlorine-containing cleaning agents during the CIP (In-line Cleaning) process, resulting in the dissolution of iron ions, which seriously affected the purity of the product and the stability of the batch.
Our solution: We custom-developed a high-purity 99.5% alumina ceramic membrane support for it, which perfectly matches its existing equipment interface and membrane package size.
The achieved effect
Completely eliminate pollution: The ceramic membrane support is completely inert to chlorine-containing cleaning agents, and there is no risk of metal ion precipitation anymore.
Extended service life: After replacement, the membrane support has been in continuous use for more than 2 years without any performance decline, while the previous stainless steel membrane support needed to be replaced on average every 6 months.
Improving product qualification rate: The purity of products and the consistency of batches have been significantly enhanced, bringing huge economic benefits to customers.
