This study aimed to evaluate the effect of coagulation pretreatment using pre-filtered MO on the fouling mitigation in the microfiltration (MF) process. MF treatment of river water without pretreatment promoted a considerable reduction in membrane permeability (i.e. membrane fouling), which was not sufficiently recovered by conventional backwashing. In contrast, MF treatment after MO coagulation substantially reduced membrane fouling. Over six filtration cycles (or a 6 h filtration period), the fouling mitigation level with MO coagulation was comparable to that with aluminium sulphate (alum) coagulation. In addition, the major water quality parameters (turbidity and colour) after MF treatment were equivalent between MO and alum coagulation. Pretreatment by MO coagulation has an advantage of maintaining water pH after MF treatment. The results obtained here suggest that MO coagulation can be employed as an effective and low-cost fouling mitigation technique for the MF process in drinking water treatment.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Environmental Science: Water Research and Technology, 4(10), pp.1604-1611; 2018","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Royal Society of Chemistry"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1039/C8EW00186C","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c The Royal Society of Chemistry."}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"20531400","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"20531419","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":"Katalo, Ronald"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okuda, Tetsuji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nghiem, Long D."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujioka, Takahiro"}],"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":"ESWRT4_1604.pdf","filesize":[{"value":"344.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ESWRT4_1604.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/1415/files/ESWRT4_1604.pdf"},"version_id":"b4ce38fe-dc26-4867-b90f-ab7a4123a6cf"}]},"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":"Moringa oleifera coagulation as pretreatment prior to microfiltration for membrane fouling mitigation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Moringa oleifera coagulation as pretreatment prior to microfiltration for membrane fouling mitigation"}]},"item_type_id":"2","owner":"2","path":["21"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-11-01"},"publish_date":"2019-11-01","publish_status":"0","recid":"1415","relation_version_is_last":true,"title":["Moringa oleifera coagulation as pretreatment prior to microfiltration for membrane fouling mitigation"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T04:02:52.839676+00:00"}
