It requires more stringent water quality assurance than indirect potable reuse. Thus, the development of a high-rejection reverse osmosis (RO) membrane for the removal of one of the most challenging chemicals in potable reuse ? N-nitrosodimethylamine (NDMA) ? ensures further system confidence in reclaimed water quality. This study aimed to achieve over 90% removal of NDMA by modifying three commercial and one prototype RO membrane using heat treatment. Application of heat treatment to a prototype membrane resulted in a record high removal of 92% (1.1-log) of NDMA. Heat treatment reduced conductivity rejection and permeability, while secondary amines, selected as N-nitrosamine precursors, were still well rejected (>98%) regardless of RO membrane type. This study also demonstrated the highly stable separation performance of the heat-treated prototype membrane under conditions of varying feed temperature and permeate flux. Fouling propensity of the prototype membrane was lower than a commercial RO membrane. This study identified a need to develop highly selective RO membranes with high permeability to ensure the feasibility of using these membranes at full scale.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Water Research, 131, pp.45-51; 2018","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier Ltd."}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.watres.2017.12.025","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2017 Elsevier Ltd."},{"subitem_rights":"This manuscript version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00431354","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Fujioka, Takahiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishida, Kenneth P."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shintani, Takuji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kodamatani, Hitoshi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-18"}],"displaytype":"detail","filename":"WatRes131_45.pdf","filesize":[{"value":"361.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"WatRes131_45.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/1074/files/WatRes131_45.pdf"},"version_id":"0a21ae5b-511e-4de6-b8d6-e892c0d47df1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Heat treatment","subitem_subject_scheme":"Other"},{"subitem_subject":"N-nitrosamine precursor","subitem_subject_scheme":"Other"},{"subitem_subject":"Potable water reuse","subitem_subject_scheme":"Other"},{"subitem_subject":"Reverse osmosis","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"High rejection reverse osmosis membrane for removal of N-nitrosamines and their precursors","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High rejection reverse osmosis membrane for removal of N-nitrosamines and their precursors"}]},"item_type_id":"2","owner":"2","path":["21"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-03-15"},"publish_date":"2020-03-15","publish_status":"0","recid":"1074","relation_version_is_last":true,"title":["High rejection reverse osmosis membrane for removal of N-nitrosamines and their precursors"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T04:08:00.690262+00:00"}
