Silicon Carbide Membrane Tube SiC Ceramic Membrane Filter

Silicon carbide ceramic membrane tube is formed by recrystallization technology through high temperature sintering, its working principle is that the raw material liquid flows at high speed in the film tube, driven by pressure difference, the clarifying liquid containing small molecular components passes through the dense layer of the membrane, the suspended substances, colloidal particles and macromolecules in the fluid are trapped and adsorbated in the micropores, so as to achieve the purpose of fluid clarification, separation, concentration and purification. Silicon carbide membrane tube has high strength, good wear resistance, high temperature resistance, corrosion resistance, no pollution, uniform porosity distribution, long service life and easy regeneration, especially suitable for all kinds of gas and liquid filtration.
