In addition, the demand for fertilizers is increasing, energy prices are rising and global phosphate reserves are declining. This requires both changes in wastewater treatment technologies and implementation of new processes. In this contribution a description is given of the combination of a ureolytic phosphate precipitation (UPP) and an autotrophic nitrogen removal (ANR) process on the anaerobic effluent of a potato processing company. The results obtained show that it is possible to recover phosphate as struvite and to remove the nitrogen with the ANR process. The ANR process was performed in either one or two reactors (partial nitritation + Anammox). The one-reactor configuration operated stably when the dissolved oxygen was kept between 0.1 and 0.35 mg L\u22121. The best results for the two-reactor system were obtained when part of the effluent of the UPP was fully nitrified in a nitritation reactor and mixed in a 3:5 volumetric ratio with untreated ammonium-containing effluent. A phosphate and nitrogen removal efficiency of respectively 83 \u00b1 1% and of 86 \u00b1 7% was observed during this experiment.<\/jats:p>","DOI":"10.2166\/wst.2013.666","type":"journal-article","created":{"date-parts":[[2013,4,4]],"date-time":"2013-04-04T09:10:53Z","timestamp":1365066653000},"page":"1425-1433","update-policy":"http:\/\/dx.doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":4,"title":["Autotrophic nitrogen removal after ureolytic phosphate precipitation to remove both endogenous and exogenous nitrogen"],"prefix":"10.2166","volume":"67","author":[{"given":"E.","family":"Desmidt","sequence":"first","affiliation":[{"name":"Department of Industrial Sciences and Technology, Katholieke Hogeschool Brugge-Oostende, Associated to the Katholieke Universiteit Leuven asFaculty of Industrial Engineering Sciences, Zeedijk 101, Oostende, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Monballiu","sequence":"first","affiliation":[{"name":"Department of Industrial Sciences and Technology, Katholieke Hogeschool Brugge-Oostende, Associated to the Katholieke Universiteit Leuven asFaculty of Industrial Engineering Sciences, Zeedijk 101, Oostende, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"De Clippeleir","sequence":"first","affiliation":[{"name":"Laboratory of Microbial Ecology and Technology (LabMET), Faculty of Bio-engineering Sciences, University of Ghent, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.","family":"Verstraete","sequence":"first","affiliation":[{"name":"Laboratory of Microbial Ecology and Technology (LabMET), Faculty of Bio-engineering Sciences, University of Ghent, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.
