Dish ceramic membrane
Product performance:
Ceramic membrane is a high temperature sintered Ceramic Filter material with porous structure, such as alumina, silicon carbide and mullite. The porous support layer, transition layer and microporous membrane layer are asymmetrically distributed, and the filtration accuracy covers microfiltration, ultrafiltration and even nanofiltration. Ceramic membrane filtration is a "cross-flow filtration" form of fluid separation process: the raw material liquid flows at high speed in the membrane, and the clarified penetrant containing small molecular components passes through the membrane in the vertical direction under the pressure drive, and the turbidated concentrated liquid containing large molecular components is trapped by the membrane, so that the fluid can achieve the purpose of separation, concentration and purification.
The ceramic membrane tray can cope with all the wastewater or materials that can be treated by traditional filtration methods, separating particles, colloids, microorganisms, viruses, macromolecules, etc., from contaminated water, but it is more recommended for challenging feed liquid systems, such as high viscosity fermentation liquid or high solid content and high concentration wastewater systems: Excellent pollution resistance, chemical resistance, heat resistance, stable operating flux.
The new concentration filtration equipment effectively combines the principle of centrifuge and ceramic membrane, which is an enhanced membrane separation technology. The membrane usually does not decay, is less affected by the concentration of the feed liquid, and the continuous and stable filtration time is long; It can effectively prevent the blockage of the filter membrane and ensure the normal filtration.
Why can the disc concentrated filter membrane replace the ceramic membrane?
Traditional tangential flow membrane filtration (cross-flow filtration, tubular membrane, etc.) is unable to help high-viscosity fluids, mainly because the membrane channel is narrow, let alone the membrane surface fouling, and even before that, the flow channel has been blocked. Even after repeated cleaning, or even manual cleaning, it can only be reluctantly dealt with in the end.
The reason why the new rotary membrane filtration concentration is so good at handling high-viscosity fluids is largely due to its completely different structure from previous filtration systems.
The new membrane adopts the disk-type design, and the loaded membrane will rotate with the high-precision axis driven by the motor to become a "rotating membrane", generating high shear force and turbulence on the surface of the membrane. The cross-flow velocity of 7m/s can remove the pollution on the surface of the membrane in a long time, so that the filter cake layer on the surface of the filter membrane is controlled in a very thin range, avoiding blockage and maintaining a stable operating flux.
Advantages: high separation efficiency, good stability, easy operation, energy saving and environmental protection, low cost, wide range of application.

In the field of oil and gas: ceramic membrane can also have a good removal effect on grease wastewater. Ceramic membranes are very resistant to emulsified oils and do not need to be replaced as frequently as organic membranes, so they are also very suitable for the treatment of oily wastewater.
In the field of seawater desalination: ceramic membrane as a pretreatment unit, can remove colloidal suspended matter and macromolecular organic matter, so as to ensure the stability of effluent water quality, and make it better used for reverse osmosis; Ceramic membranes are well suited for desalination and are more resistant to the effects of red tides and algae than organic membranes.
Groundwater treatment: Another application of ceramic membranes in the municipal sector is groundwater treatment in Middle Eastern countries, especially in Saudi Arabia and Iran. As a pretreatment unit of reverse osmosis system, it can be used to remove iron and radium from high temperature water.
Environmental protection industry: landfill leachate treatment, high-difficulty wastewater, pharmaceutical wastewater, production water reuse, oily wastewater, dye, paint treatment, papermaking wastewater, textile wastewater treatment.
