Differences between Ceramic and Organic Membranes

Flux difference:

Ceramic filtration membranes have excellent hydrophilic properties, running flux is generally 3-5 times that of organic membranes, anti-pollution ability, corrosion resistance, low energy consumption and other properties are excellent.

Service life:

The properties of ceramic materials determine that the service life of ceramic filtration membrane is more than three times longer than that of organic membranes, and the membrane materials can also be recycled.

Temperature coefficient difference:

The temperature coefficient of ceramic ultrafiltration membranes is small, and the influence of water temperature on the microstructure of ceramics is limited. When the temperature decreases by 10˙C, the output of the membrane system varies less than 1%.

Expansion coefficient difference:

The linear expansion coefficients of ceramic membrane (alumina) ¹ is ~7.2 x 10^-6, K; while organic membrane (PVDF) ² is ~14 x 10^-5, K.
