Ceramic Membrane

Ceramic membrane is a porous fine ceramic filter which is sintered from Alumina, Titania or Zirconia under ultra high temperature. Ceramic membrane normally has an asymmetrical structure with porous support active membrane layer. The macro porous support ensures the mechanical resistance while the active layer functions separation ranging from Microfiltration, Ultrafiltration and even Nano filtration (from 10nm down to 1KD). Ceramic Membrane always runs at a CROSS FLOW FILTRATION mode. The turbid fluid goes through membrane layer inside the single channel or a multi channel at a high velocity. Driven by Trans Membrane Pressure (TMP), the clean liquid with micro-molecule pass through the membrane layer vertically to permeation, the solid and big molecule is rejected in retentate. The feed fluid is thus clarified, concentrated and purified.
