%X this paper presents the results about the behavior of a sequencing batch hybrid reactor on combined removal of carbonaceous matter, nitrogen and phosphorus from sewage. operated in 8-hour cycles, the reactor had a nylon net fixed inside. loads between 0.39 and 1.35 kg cod.m-3.day-1, 42 and 60 gn-nh4-m-3.day-1 and 51 and 70 gp-po4-m-3.day-1 were tested. the reactor operated as a stable system and showed good depuration conditions. the carbonaceous matter removal was high, with 92 and 80% efficiencies average to bod5 and cod, respectively. the nutrients removal varied between 59 and 71% for total nitrogen and between 45 and 67% for total phosphorus. in both, sludge in suspension and the biofilm, occurrence of ammonium-oxidizing bacteria and microorganisms responsible for denitrification and biological phosphorus removal was observed.
