According to the comparative experimental study of critical flux test, the flux of double outlet membrane element can be increased by 18% ~ 22% compared with the traditional flat membrane element, so as to reduce the capital construction cost of the project; The chemical cleaning effect improves the phenomenon of pollution dead corner of single channel flat membrane element, improves the unit effective utilization rate and prolongs the service life of membrane element; Low transmembrane pressure difference can save operation cost and greatly enhance the market competitiveness of MBR.
