This study investigated the emission of N2O during the sequential aerated (60-min) and non-aerated (30-min) stages of an intermittent aeration cycle in an activated sludge wastewater treatment plant (WWTP). N2O emission occurred during both stages; however. emission was much higher during aeration. Air stripping is the major factor controlling transfer of N2O from the sewage to the at... https://parisnaturalfoodes.shop/product-category/spf-27-kids/
