Abstract: | The significan ce of studying the pure water flux distribution characteristics of the internal pressure-type ultra-filtration membrane fiber to the study of ultra-filtration technology is emphasized. The change law of the internal pressure membrane fiber along-path pure water flux in forms of single-ended water supply and double-ended water supply is given,and the pressure and temperature characteristics of them analyzed. The differences of the character-stics of long membrane fiber and short membrane fiber along-path flux are compared. Various technical advantages of the internal pressure type hollow ultra-filtration membrane fiber in form of double-ended water supply are made clear. A reference has been provided for the running analysis on hollow ultra-filtration membrane modules and mem-brane systems. |
