The research on inorganic ceramic membranes began in the 40s of the 20th century, but it was not until the late 80s that a breakthrough was made in its research. Although the research on inorganic ceramic membranes and separation technologies in China started late, the development speed is quite fast. Due to a series of advantages such as high temperature resistance, reliable operation and good chemical stability, the prospect of inorganic ceramic membrane technology is very broad.
The pore size distribution of inorganic ceramic membranes is narrow, and its distribution is normally distributed. The pore size within 10% of the error accounts for more than 80%, which is quite different from organic membranes. Organic membranes generally characterize the pore size of the membrane by the molecular weight cutoff, and its pore size distribution is generally dominated by average distribution. This property allows the inorganic ceramic membrane to guarantee a stable effect during the treatment process.
The ceramic membrane filter is mainly composed of a tank, an upper and lower flower plate, a ceramic membrane filtration (medium) pipe, a cleaning coil, a manhole, a water inlet and outlet pipe, a sewage pipe and an oil discharge pipe. When the wastewater passes through these tiny pores, suspended matter, colloidal particles, and macromolecular organic matter are trapped on the surface of the filter medium, and the fluid passes through the microporous channel to produce various physical effects, so as to achieve the effects of mechanical sieve filtration, purification, diffusion, and fluidization.
Ceramic membrane filter is a set of precision super filtration and purification equipment that can be widely used in various fields. Its core component, the inorganic ceramic membrane, has excellent thermal stability and pore stability, not only high strength, chemical corrosion resistance, good cleaning and regeneration performance, but also has the dual advantages of filtration and precision filtration.
The application fields of inorganic ceramic membrane technology are very wide, including but not limited to chemical production, fine chemical production, etc. In chemical production, inorganic ceramic membranes can be used for ammonia and ammonia filtration, secondary brine filtration, lye desalination filtration, decarbonization solution filtration, etc. In fine chemical production, all kinds of liquid activated carbon filtration, final solution fine filtration and purification, and raw material liquid fine filtration (acid, alkali, alcohol, ketone water, etc.) can be achieved by inorganic ceramic membrane technology.
