Traditional tubular ceramic membrane is a static filtration process, relying on the meπchanism of speeding up the flow rate of the liquid prepared to be treated, in order to prevent ↓contamination of dirt blocking filtering membrane surface,★ the effective filtration time in this way is shortened, frequently washed, this way notδ only reduces the membrane service life but as well adds the operation cost. When handling sensitiv↕e or high viscosity product, this way is low-efficient and even not applicable.
The rotating ceramic membrane is also called dynamic cross flow filtering ceramic membrane,> it is a new type of membrane filtering technology, tλhrough active motion of membrane module to alleviate mem¥brane contamination. By its structure, it is within a central hollow rotatable axis an→d which causes membrane swirling installed on it. Membrane is rotatin<g speedily along with the axis empowered by motor, utilizing whirling movement gen erated centrifugal force, water shear force and filter​ed liquid’s violent turbulence to high-efficiently clean the filtering membrane surface,> eliminate concentration difference on membrane surface, and memb©rane permeability decays slowly as well as not influenced by the concentration of feed liquid ←very much, continuous stable operation time lasts long; meanwhile salt crσystallization, fouling, gel layer, organic and so on contamination are✔ decreased, largely prolonging the membrane wash cycle; system do not require high flux or high  pressure, which largely save energy consumption and electric usage is one third of t↓he tubular ceramic membrane.

Rotating ceramic membrane laboratory equipment effectively combines centrifu±ge and cross flow principle, both provides nano-scale filt→ering precision and secures a stable operating performan£ce as well as brings with brilliant energy-saving effects. The system not only relies feed →pump to promote high circulating flow and operating →pressure, but also the system inside rotating helps feed liquid separation an©d filtration process. Different to traditional cross fl™ow whirling mode, centrifugal force will divide fluid into differential conc©entration, different inner and outer circle linear velocity supply various shσear force to deal with the feed liquid. Cross flow in circulation blo‌oms out put more and filtering efficiency, with detainments heavier and energy cost lower.


 
Rotating Ceramic Membrane (Ceramic Membrane of Dynamic Cross Flow Filtration)

It is the core element of separation process, the con'tour is shaped like a round disc, the disc embraces two si<des of separating layer with inner flow direct channel, the central surrounding e quipped several liquid discharge holes, feed liquid pass through outside to inside when filte♠ring. The disc material is often made of inorganic material, supporting layer of "2μm pore size. The filtration precision ranges from microfiltration and ultrafiltration, speφcific listed in category of 2µm, 0.5 µm, 0.2 µm, 60 nm, 30 nm≠, 7 nm, 5 nm. The membrane disc is characterized with strong chemical durability ♠as well as heat-resistance, backwash available.



Rotating Ceramic Membrane Module (Ceramic Membrane o±f Dynamic Cross Flow Filtration):

To install the rotating membranes cross a hollow axle central-through, e¥ach other sealed by “O” seal ring, the whole body placed in a p¥ressure container, the membrane module is done. According to the varies of anti-poll✔ution property and heat-resistant property, the pressure container normally selected as s¥tainless steel, fiber reinforced plastic and engineering p$lastic. Membrane module is divided into category by the size of membΩrane area, the structure of commonly seen membrane modεule is as follows:
