The research aimed to evaluate the ability of anammox process using polyester non-woven materials as biomass carrier (PNBC) for nitrogen removal in latex processing wastewater. The experiment was operated at nitrogen loading rates (NLR) of 0.5; 1.0 and 2.0 kgN/(m<SUP>3</SUP>•day). The average total nitrogen (TN) removal efficiencies were 70% - 78% at all NLRs. The effluent NH<SUB>4</SUB>-N concentration was lower than that of the Vietnamese effluent standard limit, level B of QCVN 01:2008/BTNMT (40 mgN/L), at the NLR of 0.5 and 1.0 kgN/(m<SUP>3</SUP>•day). The PNBCR was able to run at NLRs higher than 2.0 kgN/(m<SUP>3</SUP>•day) and the effluent TN and NH<SUB>4</SUB>-N may meet the standard limits if the operation of partial nitritation could achieve the NH<SUB>4</SUB>-N:NO<SUB>2</SUB>-N ratio of 1.0:1.32 and producing less nitrate. The annamox removal rates obtained at all NLRs tested were in the range of industrial N removal applications. These findings may lead to the development of the PNBCR for latex processing wastewater treatment.
