Chemical engineering etc. In their fields, they are generally subjected to solid-liquid separation in powder-liquid separation process. In addition to technological advancement, the solid-liquid separation of fine particles, particularly non-homogeneous phase solid-liquid separation, becomes extremely difficult in the super-pure particle, the size of the particle gradually. Due to the Brownian motion of the particles, the sedimentation of conventional gravity is almost impossible to use.
If we consider any kind of filtering technique as screening with filter cloth, on the one hand the deterioration of the retention performance into super fine particulate filtration worsens, on the other hand the product causes too much loss due to the limitation of the leakage, on the other hand it depends on the bridging function. Filtration cake layer particle to realize particle retention, if the grain is smaller, the formation of filtration cake layer becomes increasingly more compact, the filtration resistance is also larger, the filter speed is smaller, the rinsing is also very difficult, the result of rinsing is very poor, the strength of the work force increase.

Centrifugal separation is difficult to realize macro-scale operation, the general industrial centrifuge can separate the particle micro size, and the rinsing process is complex, labor power is heavy and yield is low. The water-power spiral devices are also a function of centrifugal separation, which allows the solid particle to maintain its separation, but essentially the liquid is applied in reciprocal wet process grades and is generally separated above the 10 micron critical particle. In the process of producing the nanometer super-fine powder by wet chemistry, the fine pure powder slurry containing impurity ions must be repeatedly cleaned to improve the product purity by removing impurity ions. In a nanometer and excellent dispersion dispersion system, solid-liquid separation into some nanometer sludge using conventional plate frame hydraulic press, high-speed centrifuge and other cleaning methods is not effective, dust loss, cloudy permeate solution, has big problems. washing water capacity, high labor power etc.
The application of CRM ceramic membrane in the field of liquid separation provides technical characteristics, due to the widespread “cross flow filtration”, excellent physical, chemical performance and mechanical strength in recent years.
