Hence, an innovative scheme has been tested to treat swine wastewater, combining a low cost anaerobic reactor, upflow anaerobic sludge blanket (UASB), with intensified constructed wetlands (aerated CWs) in a pilot scale experimental study. The swine wastewater described in this paper is produced by a swine production facility situated in North Italy. The scheme of the pilot plant consisted of: (i) canvas-based thickener; (ii) UASB; (iii) two intensified aerated vertical subsurface flow CWs in series; (iv) a horizontal flow subsurface CW. The influent wastewater quality has been defined for total suspended solids (TSS 25,025 \u00b1 9,323 mg\/l), organic carbon (chemical oxygen demand (COD) 29,350 \u00b1 16,983 mg\/l), total reduced nitrogen and ammonium (total Kjeldahl nitrogen (TKN) 1,783 \u00b1 498 mg\/l and N-NH4+ 735 \u00b1 251 mg\/l) and total phosphorus (1,285 \u00b1 270 mg\/l), with nitrates almost absent. The overall system has shown excellent performances in terms of TSS, COD, N-NH4+ and TKN removal efficiencies (99.9%, 99.6%, 99.5%, and 99.0%, respectively). Denitrification (N-NO3\u2212 effluent concentration equal to 614 \u00b1 268 mg\/l) did not meet the Italian quality standards for discharging in water bodies, mainly because the organic carbon was almost completely removed in the intensified CW beds.<\/jats:p>","DOI":"10.2166\/wst.2017.180","type":"journal-article","created":{"date-parts":[[2017,3,28]],"date-time":"2017-03-28T00:11:00Z","timestamp":1490659860000},"page":"68-78","update-policy":"http:\/\/dx.doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":21,"title":["Upflow anaerobic sludge blanket and aerated constructed wetlands for swine wastewater treatment: a pilot study"],"prefix":"10.2166","volume":"76","author":[{"given":"F.","family":"Masi","sequence":"first","affiliation":[{"name":"Iridra, Via La Marmora 51, 50121 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Rizzo","sequence":"first","affiliation":[{"name":"Iridra, Via La Marmora 51, 50121 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"Martinuzzi","sequence":"first","affiliation":[{"name":"Iridra, Via La Marmora 51, 50121 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.
