Alumina Porous Ceramic Membrane Filters Tubes
1. Direct supplier
2. Excellent corrosion and heat resistance

Brief Introduction:
Specially for the pharmaceutical and chemical industry, we offer the Alumina Ceramic Membrane Filters. They consist of a porous alumina support and a micro-pore membrane applied on their inner or outer surface, depending on the application. They are highly useful for solid-liquid separation, for chemical filtration and for phase separation. They are characterized by their high hardness, rigidness, chemical resistance to acid/alkali attack and high thermal shock resistance. They are highly useful in many beverage industry applications as well.

Typical Applications:
1) Biochemical and Pharmaceutical Industries: Clarification and purification of the fermentation products as well as purification or separation of product slurries;
2) Environmental applications: Waste Water clarification and separation;
3) Food and Beverage Industry: Microfiltration of milk, clarification of fruit juice and separation of soyabean protein;
4) Highly useful for various filtration applications in the Petro-Chemical Industry;
5) Other fields: Reclamation of nano powders, filtration of acid/alkali containing liquids.

Advantages of Ceramic Membrane Filters compared withother Filtration Devices:
1) Cross-Flow and back-flushing may be used to have higher flux rates;
2) The design is compact, saving the precious plant area. The system is a closed system, adding to the ease of operations;
3) The system is easy to clean and may be cleaned in-situ;
4) The material of construction being alumina, the filter is unaffected by chemicals (except hot concentrated H2SO4 and HF);
5) The high rigidity of the support offers resistance to elevated temperatures and pressures, thus prolonging the life of the system.

Notes:
We can provide customizations to match the designs and requirements of the end-user.
