Process Brief:
Utilizing the sieving and retention effects of alumina or zirconia membrane layers, precision separation is achieved through crossflow filtration. Through continuous recirculation and diafiltration, soluble salts, fine over-sized particles, and metal ions are effectively removed from the slurry. This process enables precise classification and deep purification of nano- to submicron-scale particles, significantly improving material purity and particle size uniformity – meeting the stringent ultra-high purity requirements of advanced applications such as MLCCs, CMP slurries, and battery materials.

Technical Advantages:

• Crossflow filtration with high-velocity feed flow across the membrane surface ensures strong fouling resistance and sustained, stable membrane flux.

• The purification process involves no phase change, low energy consumption, and continuous operation, reducing production costs.

• Membrane elements can be regenerated online through chemical cleaning, offering long service life with no secondary contamination – environmentally friendly and sustainable.

• Compared to conventional processes, ceramic membrane purification delivers higher efficiency, more consistent product purity, and greater adaptability to varying process conditions – making it the preferred technology for large-scale purification of high-purity powders, electronic materials, and rare metals.
