A study was conducted to treat palm oil mill effluent (POME) using a pilot
scale anaerobic-aerobic rotating biological contactor (RBC) . A two-stage RBC
system was set up in the Environmental Engineering Laboratory at Universiti
Teknologi Malaysia (UTM). The anaerobic RBC was utilised as the primary
treatment unit and the effluent was further treated using an aerobic RBC. The
main aims of this project were to start up the RBC system, to monitor the
anaerobic and aerobic system and to investigate the ability of the unit to treat
POME. After full .acclimatisation, continuous flow through the system exhibited
reduction efficiencies of 96%, 71% and 80% for BODs, COD and 5S
respectively.
