Characteristics of ceramic membrane
★ Material excellent - high corrosion resistance, high strength, heat resistance, suitable for solvent or oil,
and suit for many kinds of drainage.
★ Long service life- the ceramic filter membrane system has a longer service life compared with the
hollow fiber membrane, so the full life cost is the lowest.
★Energy saving - the membrane surface is not easy to stain, and the replacement structure design.
★Maintenance free -automatic control system can reduce the daily maintenance.

For example, the daily throughput 200ton/m3 system with the ceramic filtration membrane
has a great space advantage compared with that of the flat organic membrane or the hollow
fiber membrane system.
Due to high strength and corrosion resistance, ceramic membrane has many ways to regenerate
flux by such as aeration cleaning, backwashing, chemical backwashing and high-pressure flushing.

Aeration cleaning: because the structure of bubbles and ascending flow function is effectively
used, the sludge adhesion on membrane can be prevented with the minimum air volume.
Backwash: reduce clogging (increase in membrane pressure).
Chemical backwashing: good chemical resistance and no deterioration of membrane.
High-pressure cleaning: high-pressure water can remove the solid fouling on the membrane.
Product parametersMicrograph of ceramic membrane


Through different production processes can be made into symmetric- and asymmetric- type
ceramic filtration membrane. The pore structure of ceramic filter membrane can be
obtained through pore size control.
Pore distribution of ceramic filtration membrane sheetTrans-membrane pressure
The relationship between flux and pressure, the flux can be quickly recovered by simple cleaning.
Moreover, the trans-membrane pressure (TMP) of the ceramic filter membrane is 50% lower than that of the organic membrane.

Hydrophilic
Ceramic materials are inherently hydrophilic, less wetting than water, and water spreads on the surface of ceramic membrane, which is more conducive to sewage separation than organic materials.

Water temperature calibration
For application with large temperature variations, temperature correction should be taken in consideration. The calibration coefficient is set to 1 at 25℃. The calibration coefficient is read out from Figure 1-8 according to the actual design temperature. The actual design flux is the product of nominal flux at 25℃ and temperature correction coefficient.
