Researchers have reviewed the challenges of using the nitritation-anammox process (NAP) for biological nitrogen removal in wastewater treatment. The open-access article describing their findings appears in the July issue of Water Environment Research (WER). When compared with conventional biological nitrogen removal methods in sidestream settings, NAP has the potential to reduce oxygen requirements for wastewater […]
