Air supply was considered through continuous or intermittent aeration (CA vs. IA), and several values were assumed for the SW BOD<sub>5<\/sub>-to-N ratio. By considering CA and low dissolved oxygen (DO) levels, feasibility for peforming N removal via nitrite through simultaneous nitrification\u2013denitrification was confirmed. Nitrogen removal via nitrite was also the case when applying IA, even at higher DO ranges. The nitrite short-cut was shown to reduce energy consumption for aeration. However, regardless of the aeration method applied, sensitive DO controls will be required, particularly when the SW BOD<sub>5<\/sub>-to-N ratio takes low values. This study allowed to assess the operational conditions required when biologically treating SW to meet N standards and to identify situations in which a final post-treatment is needed before effluent discharge.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-2c172926 ts-col-stretched-none ts-bg-color-over-image elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"2c172926\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-20696027 ts-bg-color-over-image\" data-id=\"20696027\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-68a112b4 elementor-widget elementor-widget-accordion\" data-id=\"68a112b4\" data-element_type=\"widget\" data-widget_type=\"accordion.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-accordion\">\n\t\t\t\t\t\t\t<div class=\"elementor-accordion-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-1751\" class=\"elementor-tab-title\" data-tab=\"1\" role=\"button\" aria-controls=\"elementor-tab-content-1751\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon elementor-accordion-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-closed\"><i class=\"fas fa-plus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-opened\"><i class=\"fas fa-minus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-accordion-title\" tabindex=\"0\">Informaci\u00f3 addicional<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-1751\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"1\" role=\"region\" aria-labelledby=\"elementor-tab-title-1751\"><table style=\"border: hidden;\">\n<tbody>\n<tr style=\"border-bottom: 1px solid #efefef;\">\n<td align=\"right\" width=\"200\"><strong>Year:<\/strong><\/td>\n<td>2020<\/td>\n<\/tr>\n<tr style=\"border-bottom: 1px solid #efefef;\">\n<td align=\"right\" width=\"200\"><strong>Authors:<\/strong><\/td>\n<td>Waki M., Yasuda T., Fukumoto Y., B\u00e9line F., Magr\u00ed A.<\/td>\n<\/tr>\n<tr style=\"border-bottom: 1px solid #efefef;\">\n<td align=\"right\" width=\"200\"><strong>Reference:<\/strong><\/td>\n<td>\n<p>Bioresource Technology Reports, Volume 11, September 2020, Article number 100492<\/p>\n<\/td>\n<\/tr>\n<tr style=\"border-bottom: 1px solid #efefef;\">\n<td align=\"right\" width=\"200\"><strong>Link:<\/strong><\/td>\n<td><a href=\"http:\/\/dx.doi.org\/10.1016\/j.biteb.2020.100492\" target=\"_blank\" rel=\"noopener\">http:\/\/dx.doi.org\/10.1016\/j.biteb.2020.100492<\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2dab7ba7 elementor-widget elementor-widget-spacer\" data-id=\"2dab7ba7\" data-element_type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Authors: Waki M., Yasuda T., Fukumoto Y., B\u00e9line F., Magr\u00ed A.
