| Abstract: | Membrane microfiltration enhancement by rotary tangential flow is a new enhanced microfiltration technique which working principle is based on the hydrocyclone principle.It improves the structure of membrane separator and the form of suspension entering the separator,so as to increase membrane fluxes and decrease membrane fouling.The rotary tangential flow tubular membrane separator and its test system were first developed.Through theoretical study and actual test,the flow field characteristics of rotary linear tangential flow and rotary circular tangential flow polypropylene tubular membrane microfiltration and the revealed mechanism of rotary tangential flow enhancing membrane microfiltration were studied systematically. |
