Abstract: According to the tests on the two coefficients of the fiber wall permeability and along-path resistance of the hollow and internal-pressure ultra-filtration fiber,the pressure drop of axial runoff of the membrane modules outside the fiber space has been analyzed,so as to establish the running differential equation model of pressure drop of axial runoff of internal pressure membrane modules. The distribution laws of along-path parameters inside and outside the membrane fiber,under different volume rates of membrane modules,are discussed. The relationships among volume ratio,pure water flux and produced water flow rate of hollow and internal-pressure ultra-filtration membrane module have been analyzed quantitatively.
