• Simultaneous organic carbon removal-nitrification was carried out by an activated sludge process with cross-flow filtration while retaining a higher concentration of activated aludge. Operating the unit at ca. 0.10 gBOD・gVSS^<-1>.d^<-1> made the sludge retention wime very long and simultaneous carbon removal-nitrification was achieved quite well. Compared with conventional activated processes, the present process made possible nearly twice the organic volumetric loading by increasing the sludge concentration five-fold. A nitrification rate of ca. 0.30g TKN.l^<-1>.d<-1> was attained. More than 27% of the oxidized nitrogen in the reactor was denitrified at the same time in most cases.
