Working Principle Of Ceramic Membrane Filter Element
The working principle of ceramic membrane filter is based on a dual mechanism of physical filtration and pressure drive. Its core lies in its tiny pore structure, which typically has a diameter in the nanometer range, providing a natural barrier for impurities and suspended solids in the solution. When the liquid to be processed flows through the ceramic membrane filter, these tiny pores only allow small molecules (such as water molecules) to pass through smoothly, while large molecules (such as proteins, colloidal particles, suspended solids, and microorganisms) are effectively intercepted.
Detailed explanation of working principle
Pore screening: The pore diameter of ceramic membrane filters is at the nanometer level, and the filtering mechanism of size exclusion ensures the high purity of the filtered liquid. This size exclusion based filtering mechanism allows only small molecules to pass through, while large molecules are intercepted.
Pressure difference drive: The operation of ceramic membrane filters depends on the pressure difference applied externally. During the filtration process, the liquid on the high-pressure side is forced to pass through the tiny pores of the ceramic membrane under pressure and flow towards the low-pressure side. During this process, the pressure difference not only drives the flow of the liquid, but also enhances the filtration effect.
Separation effect: Ceramic membrane filters can achieve precise separation of micro - or even nano scale particles and microorganisms in solution. This high-precision filtration capability is attributed to the excellent performance of ceramic membrane materials and advanced manufacturing processes
