SiC Ceramic Flat Membrane

Semicorex SiC ceramic flat membranes are fabricated using a special recrystallization sintering technique, during which the nano-powder undergo a transformation from solid to gas and back to solid phase. This fabrication method results in SiC ceramic flat membranes with low dead porosity and excellent three-dimensional channel connectivity. Different from the 25%~35% open porosity of conventional alumina and zirconia ceramic membranes, SiC ceramic flat membranes can boast an open porosity of over 45%, thus delivering exceptional permeability for industrial separation applications.

Semicorex SiC ceramic flat membranes exhibit a gradient pore structure, which is composed of three-layer composite structure: a 0.04µm dense microporous separation layer, a 0.5µm dense microporous secondary separation layer, and an 8µm open macroporous support layer. This special-designed gradient pore structure achieves precise physical sieving of molecules, particles, or ions of different sizes. Substances smaller than the pore size can pass through the membrane pores smoothly, while substances larger than the pore size are retained on the membrane surface or within the pores, thus achieving efficient separation and filtration.

The Advantages of Semicorex SiC ceramic flat membranes

1. High flux performance

The flux of Semicorex SiC ceramic flat membranes is three times that of conventional ceramic membranes and 20 times that of organic membranes, which enables unparalleled efficiency in wastewater and sewage treatment.

2. Safety performance

Thanks to the single-component raw material, Semicorex SiC ceramic flat membranes undergone multiple high-temperature sintering processes will release zero impurity or heavy metal leaching during wastewater treatment.

3. Anti-fouling Properties

The chemical properties and charge distribution on the surface of Semicorex SiC ceramic flat membranes allow for adsorption (e.g., heavy metal ions or organic pollutants) or repulsion (e.g., oily substances), giving them excellent anti-fouling capabilities.Good Economic Efficiency: SiC ceramics offer a longer lifespan than conventional materials, which greatly reduce Semicorex SiC ceramic flat membranes’ maintenance and replacement costs. Compared with conventional membranes, They require less floor space, lower operating costs, and less initial investment.
