Analysis on Energy Consuming of Polypropylene Tubular Membrane Microfiltration in Rotating Tangential Flow

A new type of polypropylene tubular membrane module in rotating tangential flow was designed to experimentally study energy consuming of the polypropylene PA tubular membrane microfiltration. Through the experimental system of rotating tangential flow which was set up to enhance the microfiltration, the polypropylene PA tubular membrane fluxes and energy efficiency of rotating tangential flow and axial flow were measured under different fluid pressures. The experimental results demonstrate that rotary tangential flow tubular membrane microfiltration was a high efficiency technology of membrane separation. At test conditions, the stable energy efficiency of linear and circular tangential flow were higher than 11.185 times and 14.591 times of the stable energy applying efficiency of axial flow respectively.
