New geometry of ceramic tubular membranes were designed to overcome the imp
ortant problem of fouling encountered in micro- and ultrafiltration, by pro
moting turbulence and particle draining close to the membrane surface. Micr
ofiltration tests showed the efficiency of these new membranes and a hydrod
ynamic study was carried out to improve our knowledge on the antifouling ph
enomenon achieved with these membranes. The potential application of these
new membranes for an industrial development was also investigated. (C) 2001
