{"id":"https://openalex.org/T10564","display_name":"Wastewater Treatment and Nitrogen Removal","description":"This cluster of papers focuses on the microbial nitrogen cycle in biological wastewater treatment systems, including the roles of nitrifying and denitrifying bacteria, anammox bacteria, and extracellular polymeric substances. It covers topics such as complete nitrification, partial nitritation/anammox, biological phosphorus removal, and nitrous oxide emission during wastewater treatment.","keywords":[{"id":"https://openalex.org/keywords/nitrogen-removal","display_name":"nitrogen removal","score":0.4779},{"id":"https://openalex.org/keywords/activated-sludge","display_name":"activated sludge","score":0.4982},{"id":"https://openalex.org/keywords/denitrification","display_name":"denitrification","score":0.2991},{"id":"https://openalex.org/keywords/nitrification","display_name":"nitrification","score":0.3146},{"id":"https://openalex.org/keywords/phosphorus-removal","display_name":"phosphorus removal","score":0.2781},{"id":"https://openalex.org/keywords/sequencing-batch-reactor","display_name":"sequencing batch reactor","score":0.7292},{"id":"https://openalex.org/keywords/anammox","display_name":"anammox","score":0.7813},{"id":"https://openalex.org/keywords/hydraulic-retention-time","display_name":"hydraulic retention time","score":0.2648},{"id":"https://openalex.org/keywords/ammonium-removal","display_name":"ammonium removal","score":0.3934},{"id":"https://openalex.org/keywords/biological-nitrogen-removal","display_name":"biological nitrogen removal","score":0.9002},{"id":"https://openalex.org/keywords/nitrate-removal","display_name":"nitrate removal","score":0.3041},{"id":"https://openalex.org/keywords/extracellular-polymeric-substances","display_name":"extracellular polymeric substances","score":0.2289},{"id":"https://openalex.org/keywords/biological-wastewater-treatment","display_name":"biological wastewater treatment","score":0.4413},{"id":"https://openalex.org/keywords/activated-sludge-process","display_name":"activated sludge process","score":0.7261},{"id":"https://openalex.org/keywords/municipal-wastewater-treatment","display_name":"municipal wastewater treatment","score":0.2982},{"id":"https://openalex.org/keywords/ammonia-oxidizing-bacteria","display_name":"ammonia-oxidizing bacteria","score":0.4502},{"id":"https://openalex.org/keywords/membrane-bioreactor","display_name":"membrane bioreactor","score":0.2283},{"id":"https://openalex.org/keywords/sludge-retention-time","display_name":"sludge retention time","score":0.5803},{"id":"https://openalex.org/keywords/biological-nutrient-removal","display_name":"biological nutrient removal","score":0.7657},{"id":"https://openalex.org/keywords/aerobic-granular-sludge","display_name":"aerobic granular sludge","score":0.8578},{"id":"https://openalex.org/keywords/nitrifying-bacteria","display_name":"nitrifying bacteria","score":0.4132},{"id":"https://openalex.org/keywords/nitrite-accumulation","display_name":"nitrite accumulation","score":0.6298},{"id":"https://openalex.org/keywords/denitrifying-bacteria","display_name":"denitrifying bacteria","score":0.4542},{"id":"https://openalex.org/keywords/ammonia-removal","display_name":"ammonia removal","score":0.2517},{"id":"https://openalex.org/keywords/biological-phosphorus-removal","display_name":"biological phosphorus removal","score":0.8733}],"legacy_keywords":"Nitrogen-Cycling Network; Anammox Bacteria; Extracellular Polymeric Substances; Nitrifying Bacteria; Denitrifying Bacteria; Biological Phosphorus Removal; Activated Sludge; Wastewater Treatment; Nitrous Oxide Emission; Anaerobic Ammonium Oxidation","ids":{"openalex":"https://openalex.org/T10564","wikipedia":"https://en.wikipedia.org/wiki/Wastewater_treatment"},"subfield":{"id":"https://openalex.org/subfields/2310","display_name":"Pollution"},"field":{"id":"https://openalex.org/fields/23","display_name":"Environmental Science"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"},"siblings":[{"id":"https://openalex.org/T10139","display_name":"Heavy metals in environment"},{"id":"https://openalex.org/T10324","display_name":"Microbial bioremediation and biosurfactants"},{"id":"https://openalex.org/T10419","display_name":"Pharmaceutical and Antibiotic Environmental Impacts"},{"id":"https://openalex.org/T10753","display_name":"Microplastics and Plastic Pollution"},{"id":"https://openalex.org/T11180","display_name":"Pesticide and Herbicide Environmental Studies"},{"id":"https://openalex.org/T11336","display_name":"Energy and Environment Impacts"},{"id":"https://openalex.org/T12316","display_name":"Oil Spill Detection and Mitigation"},{"id":"https://openalex.org/T12682","display_name":"Smart Materials for Construction"},{"id":"https://openalex.org/T13916","display_name":"Environmental Policies and Emissions"},{"id":"https://openalex.org/T14120","display_name":"Thallium and Germanium Studies"}],"works_count":127900,"cited_by_count":1693328,"works_api_url":"https://api.openalex.org/works?filter=topics.id:T10564","updated_date":"2026-10-22T03:01:35","created_date":"2024-01-23T15:27:07"}
