Abstract: Slaughterhouse wastewater (SWW) possesses very high organic and nutrient concentrations and its residues are moderately solubilized, which leads to pollution affecting the environment and human health. The objective of this study was to investigate the effective removal of ammonium in slaughter wastewater by up flow anaerobic sludge blanket (UASB) technology combined with an expanded granular sludge bed (EGSB) using anammox and PVA gel as the biomass carrier. The result showed that the removal efficiencies of nitrite were about 55% (NLRs=0.25 kg N-NH₄⁺/m³.d), 77% (NLRs=0.5 kg N-NH₄⁺/m³.d), and 73% (NLRs=0.75 kg N-NH₄⁺/m³.d). In addition, the removal efficiencies of ammonium were about 56% (NLRs=0.25 kg N-NH₄⁺/m³.d), 68% (NLRs=0.5 kg N-NH₄⁺/m³.d), and 60% (NLRs=0.75 kg N-NH₄⁺/m³.d).
