The pilot plant was fed with a mixed domestic-textile wastewater (textile wastewater accounted for 65% of total flow and for 70% of total chemical oxygen demand, COD, load) and operated for 7.5 months without flux enhancers (step 1) and 3 months with the addition of PACl (step 2). The optimum dose was defined performing a jar-test campaign between step 1 and step 2 (12.5 mg gMLSS\u22121 that corresponds to 0.4 g d\u22121). The addition of PACl resulted in a significant decrease of the filtration resistance due to cake layer formation (Rc, \u221265.4%) and of the irreversible fouling rate, evaluated as the average variation per unit time of the filtration resistance due to foulants adsorption on membrane pore wall (FR, \u221245.3%). As for permeate quality, removal rates related to total phosphorus and textile macro-parameters such as colour and anionic surfactants, increased by +64, +16 and +7%, respectively. No significant effect was observed on COD, non-ionic surfactants and nitrogen compounds removal.<\/jats:p>","DOI":"10.2166\/wst.2012.315","type":"journal-article","created":{"date-parts":[[2012,7,25]],"date-time":"2012-07-25T09:57:44Z","timestamp":1343210264000},"page":"1289-1295","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":9,"title":["MBR fouling control and permeate quality enhancement by polyaluminium chloride dosage: a case study"],"prefix":"10.2166","volume":"66","author":[{"given":"A.","family":"Teli","sequence":"first","affiliation":[{"name":"Politecnico di Milano, DIIAR, Environmental Section, Piazza Leonardo da Vinci 32, 20133 Milano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Antonelli","sequence":"first","affiliation":[{"name":"Politecnico di Milano, DIIAR, Environmental Section, Piazza Leonardo da Vinci 32, 20133 Milano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.","family":"Bonomo","sequence":"first","affiliation":[{"name":"Politecnico di Milano, DIIAR, Environmental Section, Piazza Leonardo da Vinci 32, 20133 Milano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"Malpei","sequence":"first","affiliation":[{"name":"Politecnico di Milano, DIIAR, Environmental Section, Piazza Leonardo da Vinci 32, 20133 Milano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"945","container-title":["Water Science and Technology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/iwaponline.com\/wst\/article-pdf\/66\/6\/1289\/443314\/1289.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/iwaponline.com\/wst\/article-pdf\/66\/6\/1289\/443314\/1289.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,28]],"date-time":"2020-03-28T01:46:18Z","timestamp":1585359978000},"score":1,"resource":{"primary":{"URL":"https:\/\/iwaponline.com\/wst\/article\/66\/6\/1289\/17211\/MBR-fouling-control-and-permeate-quality"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,9,1]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2012,9,1]]}},"URL":"https:\/\/doi.org\/10.2166\/wst.2012.315","relation":{},"ISSN":["0273-1223","1996-9732"],"issn-type":[{"value":"0273-1223","type":"print"},{"value":"1996-9732","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2012,9,1]]},"published":{"date-parts":[[2012,9,1]]}}}
