Abstract

High-strength ammonium (NH₄⁺) wastewaters are difficult to be treated biologically. 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.
