Ammonia oxidation from landfill leachate by batch reactors with biological additive and subject to low pH

Fabiane Karen Godoy, Dagoberto Yukio Okada, Cassiana Maria Reganhan Coneglian

The use of a biological additive could improve the treatment of some recalcitrant wastewaters. Hence, this study evaluated the effect of biological additive (Component E) inoculation in the aerobic biological treatment of domestic sewage combined with landfill leachate. Two sequential batch reactors …

Pilot-scale study of a structured bed reactor for nitrogen and organic matter removal from sanitary sewage: advances and design challenges

Kiemi de Brito Murata, Bruno Garcia Silva, Carla Eloísa Diniz dos Santos, Dagoberto Yukio Okada et autres

Simultaneous nitrification and denitrification (SND) is a process that can remove both nitrogen and organic matter in a single unit. Several bench-scale studies show that the structured bed reactors (STBR) subjected to recirculation and intermittent aeration have achieved a good performance for …

Practical implications of methanotrophic denitrification as post‐treatment unit of anaerobic effluents in tropical areas

Rachel Biancalana Costa, Dagoberto Yukio Okada, Eugênio Foresti

Abstract BACKGROUND The use of methane as electron donor for denitrification addresses nitrogen removal in anaerobic effluents and can help to abate greenhouse gas emissions from wastewater treatment plants. However, applicable rates of methanotrophic denitrification were only reached under temperature controlled conditions, …
