NITROGEN AND PHOSPHORUS REMOVAL OF PILOT SCALE PLANT USING UMBR (UPFLOW MULTI-LAYER BIO REACTOR) AS ANAEROBIC/ANOXIC REACTORIn this study, combined UMBR(upflow multi-layer bio reactor)-activated sludge-clarifier system by single-sludge, called the KNR (Kwon's nutrient removal), was operated for the treatment of sewage during 9 months. The UMBR using plug flow reaction can function as anaerobic tank, anoxic tank, primary settling tank, and thickener and requires low mixing energy by upflowing stream. The operational...Author(s)Joong-Chun KwonAn Jin-YoungKwang-Bo ShimHang-Sik ShinHang-Bae JunSourceProceedings of the Water Environment FederationSubjectSession 25 Municipal Wastewater Treatment Processes: Biological Nutrient Removal Applications and OptimizationDocument typeConference PaperPublisherWater Environment FederationPrint publication date Jan, 2003ISSN1938-6478SICI1938-6478(20030101)2003:10L.369;1-DOI10.2175/193864703784678793Volume / Issue2003 / 10Content sourceWEFTECFirst / last page(s)369 - 385Copyright2003Word count161
