A ceramic membrane is an inorganic membrane with a special selective separation function.
It adopts dynamic "cross-flow filtration" which is completely different from traditional "full filtration", "filter cake filtration" and other filtration methods.
The separation of substances is achieved by the sieving effect of the membrane layer.
Driven by pressure, the material flows at a high speed in the ceramic membrane tube and has a certain pressure.
When the material flows through the membrane surface, the small molecular substances penetrate the membrane surface vertically, while the macromolecular substances are trapped and washed away, so as to achieve the separation effect.
Ceramic membrane separation technology has the characteristics of high efficiency, energy saving, environmental protection, and nano-filtration, and no chemical reaction occurs during the separation process.
The inorganic ceramic membrane is a precision ceramic filter material with a porous structure, which is sintered at high temperatures such as alumina, titania, zirconia, etc.
The porous support layer, transition layer, and microporous membrane layer are distributed asymmetrically, and the filtration accuracy covers microfiltration. , ultrafiltration, nanofiltration.
Ceramic membrane filtration is a fluid separation process in the form of "cross-flow filtration": the raw material liquid flows at a high speed in the membrane tube, and the clear permeate containing small molecular components is driven by the pressure to permeate the membrane in a direction perpendicular to it.
The turbid concentrate of macromolecular components is retained by the membrane so that the fluid can achieve the purpose of separation, concentration, and purification.

Product classification

Different membrane tubes, it is mainly divided into two series: ceramic membrane tubes and ceramic composite membrane tubes.
According to different pore sizes, it is mainly divided into two series: ceramic microfiltration membrane tube and ceramic ultrafiltration membrane tube.
According to the number of channels, it is mainly divided into two categories: single-channel and multi-channel.
We can select suitable ceramic membrane tubes or ceramic composite membrane tubes for customers according to customer process requirements, different processing systems, and related technical requirements.
