Centrifugal Membrane filtration is a kind of new separation utilization in membrane filtration technology, by dynamic whirling of membrane modules to accomplish alleviation of membrane pollution. Telling from its structure, its hollow axle spins driving leaves (in disc form fixed central-through-axial) rotating along with it. When membranes are high-speedily swirling with the axis by motor empowered driven force, centrifuge and shear force along with the dynamic turbulence of the filtered liquid caused by the rotating movement could high-effectively cleanse the membrane filtrating layer, eliminate the concentration polarization on membrane surface, where membrane permeability decays slowly and not easily influenced to raw liquid concentration, continuous and stable filtering period lasts long; Meanwhile the technology reduces salt crystallization, fouling, gel-layer, organics and so on contamination, largely expands the chemical wash period of the filtering membrane; And the system does not require very high flow or pressure, hugely saving the energy consumption, the electricity taken merely occupies one third of the tubular ceramic membrane.

Centrifugal Membrane Device successfully combines the mechanisms of centrifugal separation and cross flow filtration . Not only It equips nano-scale filtering precision but also makes stable operating performance certainly and brings with brilliant energy-saving effect. The system runs without relying on feed pump providing large flow volume circulation but inner swirling motion to achieve results of separation and filtration of raw liquid. Compared with traditional cross flow method, the rotation structure divides flow into high to low graded concentration by centrifuge force, through different line speed of the inner and outer circle supplying to different centrifuge force to treat the pollutants. Centrifugal filtration could enhance the permeability which makes filtration more efficient, circles of concentration higher, detainments more condensed, product yield higher, water-adding less and energy consumption lower. 

Centrifugal Membrane:

It is the core element of separation process, the contour is shaped round or square, the membrane embraces two sides of separating layer with inner flow direct channel, the central surrounding equipped several liquid discharge holes, feed liquid pass through outside to inside when filtering. The disc material is often made of inorganic material or organic material. The filtration precision ranges from microfiltration and ultrafiltration to a series of molecular weight, specific listed in category of 2µm, 0.5 µm, 0.2 µm, 60 nm, 30 nm, 7 nm, 5 nm, 100KD, 50KD, 30KD, 20KD, 10KD, 5KD, 1KD, etc. Inorganic membrane is characterized with its strong chemical durable property as well as heat-resistant property, backwash available; Organic membrane acts of extremely fine filtering precision, suitable in every aspects of separation and purification.

Centrifugal Membrane Module:

To install the centrifugal membranes cross a hollow axle central-through, each other sealed by “O” seal ring, the whole body placed in a pressure container, the membrane module is done. According to the varies of anti-pollution property and heat-resistant property, the pressure container normally selected as stainless steel, fiber reinforced plastic and engineering plastic.
