Aerobic granules are regarded as a promising technology for NH4+ removal from wastewaters. Adsorption using aerobic granules in 50-4000mg NH4+-N/L wastewaters was studied at 30°C. Adsorption capacity was increased with 50-1000mg NH4+-N/L and reached plateau of 24.5mg NH4+-N/g-volatile suspended solids at >2000mg NH4+-N/L. Ion exchange mechanism controls adsorption at <300mg NH4+-N/L and physisorption mechanism dominates the process at >1000mg NH4+-N/L. The biomass of aerobic granules presents a recyclable adsorbent for NH4+ from high-strength wastewaters. ? 2013 Taiwan Institute of Chemical Engineers.Aerobic granulesAmmonium adsorptionHigh concentration[SDGs]SDG11journal article10.1016/j.jtice.2013.04.0172-s2.0-84894226037https://www.scopus.com/inward/record.uri?eid=2-s2.0-84894226037&doi=10.1016%2fj.jtice.2013.04.017&partnerID=40&md5=6c90be9bcacdc351fa91029a156ab9aa
