Membrane filtration series

Product introduction

Tubular ceramic membrane filter

Tubular ceramic membrane filter is a kind of " Dynamic filtering " The form of fluid separation process: the raw material liquid flows at high speed in the membrane tube, and the clarified penetrant containing small molecular components passes through the membrane along the vertical direction under the pressure drive, and the cloudy concentrated liquid containing large molecular components is trapped by the membrane, so that the fluid can achieve the purpose of separation, concentration and purification.

Product characteristics

The inorganic ceramic membrane has some advantages that cannot be compared with the traditional separation media such as plate frame, centrifuge, diatomite and polymer membrane

Equipment selection

Ceramic membrane is a kind of precision filter material with porous structure, which is sintered at high temperature by alumina, titanium oxide, zirconia, etc. The porous support layer, transition layer and microporous membrane layer are asymmetrical distribution, and the filtration accuracy covers microfiltration, ultrafiltration and even nanofiltration.
Inorganic ceramic membrane pipe has the advantages of high temperature resistance (multi-channel <150℃, the maximum working temperature of single channel pipe can reach 800 ℃), high pressure resistance (maximum working pressure can reach 16MPa), acid and alkali resistance (PH0 ~ 14), high porosity (35%), uniform aperture, high mechanical strength, long service life, clean, tasteless, non-toxic and so on. Filter pore size up to 1.2, 0.8, 0.2, 0.1μ m, ultrafiltration 50, 30nm,5nm.

Membrane housing assembly

The membrane component is a pressure shell for assembling ceramic membrane components. According to the needs of industrial production, the ceramic membrane components with different outer diameters and different areas can be centrally loaded through different specifications of membrane component shells. The filling film area of a single film assembly ranges from 0.05 square meters to 20 square meters. The shape design and sealing design of the membrane components are very important to the operation of the ceramic membrane complete system.
