Sensitivity analysis of parameters on pure water flux for inside-out hollow ultrafiltration membrane fiber

The internal factors that affect the flux of inside-out hollow UF (ultra filtration) membrane fiber were simplified as “fiber radial permeability coefficient” and “fiber axial resistance coefficient”.

Description
Summary:The internal factors that affect the flux of inside-out hollow UF (ultra filtration) membrane fiber were simplified as “fiber radial permeability coefficient” and “fiber axial resistance coefficient”. The two coefficients were tested and analyzed by using hydrophilic short fiber and hydrophobic fiber respectively. A filtration mathematical model was successfully developed to describe the operation of the hollow fiber. The sensitivity function of average pure water flux, such as fiber length, inside diameter and permeability coefficient, was established. The influence of single parameter change on pure water flux of membrane fiber was analyzed. The results showed that the longer the film length was, the lower the average flux was; the bigger the wire diameter was, the higher the average flux was; the higher the temperature was, the greater the average flux was; the higher the pressure was, the greater the average flux was.
