(POME) was studied at four different mixing regimes ie natural mixing (NM), minimal
horizontal mixing (MHM), minimal horizontal and vertical mixing (MHVM) and vigorous
mixing (VM). The chemical oxygen demand (COD) removal efficiency recorded satisfactory
result at higher than 90% when subjected to the first three mixing regimes but reduced to the
lowest of 85% when VM was applied. In the NM, MHM and MHVM experiments, the …
