What is a ceramic filter?

It is a microfiltration device that uses a ceramic membrane as a filter, and is used for separating and concentrating various raw materials and recycling various processing and cleaning liquids. By separating and concentrating raw materials, it leads to improvement of product quality and creation of added value. In addition, filtering waste liquid leads to waste reduction and environmental protection.Since the filter element is made of fine ceramics, it has excellent durability. Taking advantage of this, it is possible to eliminate the clogging that accompanies filtration by performing cleaning and firing, and to reuse the element repeatedly.

Features of ceramic filter

The ceramic filter uses cross-flow filtration, which constantly flushes the deposits on the filtration membrane while filtering, and is equipped with an automatic backwash / flushing mechanism to achieve more stable microfiltration.



1. High filtration accuracy

Made of high-purity alumina ceramics, the pore distribution on the film surface is uniform, and high filtration accuracy can be obtained.


2. High corrosion resistance and heat resistance

Repeated chemical cleaning is possible. In addition, steam sterilization at about 120 ° C is possible.


3. High strength and wear resistance

Since it is excellent against internal pressure destruction, filtration of highly viscous liquid and slurry liquid is also effective.


4. Backwash reproducibility

Back pressure cleaning is possible, and a good and stable filtration flux can be obtained for a long time.


5. Abundant pore sizes

We have pore diameters from 5 nm to 1.4 μm, so you can select the membrane according to your application.


6. Maintenance free

It has excellent strength, corrosion resistance, abrasion resistance, and chemical resistance, and can build a maintenance-free system.


* We will also sell the element alone and return to cleaning. Please feel free to order.
