Tannic acid was used as a model organic foulant for natural organic matter analysis since the main characteristics are similar, and calcium ions were added at different concentrations to explore the anti-pollution capability of FO membranes. The initial permeate flux and calcium ions strength were varied in different operating conditions to describe membrane fouling with membrane cleaning methods. The observed flux decline in FO changed dramatically with the type of foulant and the type of draw solution used to provide the osmotic driving force. Calcium ions aggravated membrane fouling and decreased transmembrane flux. Membrane cleaning methods included physical and physicochemical approaches, and there was no obvious difference among the typical cleaning methods (i.e., membrane flushing with different types of cleaning fluids at various crossflow velocities and backwashing with varying osmotic driving forces) with respect to flux recovery. Ultrasonic cleaning damaged the membrane structure and decreased permeate flux, and reverse diffusion of salt from the draw solution to the feed side accelerated after cleaning.<\/jats:p>","DOI":"10.2166\/wst.2017.392","type":"journal-article","created":{"date-parts":[[2017,9,12]],"date-time":"2017-09-12T00:27:36Z","timestamp":1505176056000},"page":"3160-3170","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":11,"title":["Effects of tannic acid on membrane fouling and membrane cleaning in forward osmosis"],"prefix":"10.2166","volume":"76","author":[{"given":"Wanzhu","family":"Zhang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Pollution Control and Resource Reuse, School of Environmental Science and Engineering, Tongji University, Shanghai 200092, China and Key Laboratory of Yangtze Water Environment of Ministry of Education, School of Environmental Science and Engineering, Tongji University, Shanghai 200092, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lin","family":"Wang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Pollution Control and Resource Reuse, School of Environmental Science and Engineering, Tongji University, Shanghai 200092, China and Key Laboratory of Yangtze Water Environment of Ministry of Education, School of Environmental Science and Engineering, Tongji University, Shanghai 200092, China"},{"name":"School of Municipal and Environmental Engineering, Shandong Jianzhu University, Jinan 250101, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bingzhi","family":"Dong","sequence":"first","affiliation":[{"name":"State Key Laboratory of Pollution Control and Resource Reuse, School of Environmental Science and Engineering, Tongji University, Shanghai 200092, China and Key Laboratory of Yangtze Water Environment of Ministry of Education, School of Environmental Science and Engineering, Tongji University, Shanghai 200092, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"945","published-online":{"date-parts":[[2017,9,11]]},"reference":[{"issue":"1","key":"2020032809593033000_WST-EM17548R1C1","first-page":"10","article-title":"The forward osmosis membrane bioreactor: a low fouling alternative to MBR processes","volume":"239","year":"2009","journal-title":"Desalination"},{"key":"2020032809593033000_WST-EM17548R1C2","first-page":"101","article-title":"Effects of scaling and cleaning on the performance of forward osmosis hollow fiber membranes","volume":"415","year":"2012","journal-title":"Journal of Membrane Science"},{"key":"2020032809593033000_WST-EM17548R1C3","doi-asserted-by":"crossref","first-page":"2","DOI":"10.1016\/j.desal.2015.01.041","article-title":"Desalination techniques \u2013 a review of the opportunities for desalination in agriculture","volume":"364","year":"2015","journal-title":"Desalination"},{"issue":"1","key":"2020032809593033000_WST-EM17548R1C4","first-page":"85","article-title":"Membrane contactor processes for wastewater reclamation in space part I.
