| Abstract: | A new type of polypropylene tubular membrane module in rotating tangential flow was designed to experimentally study the polypropylene PA tubular membrane microfiltration flux.Through the experimental system of rotating tangential flow which was set up to enhance the microfiltration,the polypropylene PA tubular membrane fluxes of rotating tangential flow and axial flow were measured under different concentrations of SiO 2 suspension and different fluid pressures.The experimental results show that the rotating tangential flow membrane module to enhance microfiltration is not only energy saving but also simple in system structure,and the PA tubular membrane flux of rotating tangential flow is 1.6～2.5 times that of the axial flow. |
