Experiments were performed with reconstituted fish breeding effluent on an experimental submerged fixed-bed reactor under pressure. The filter medium consisted of a calcinid clay (Biogrog, 1.2-1.5mm) with a specific surface area (10<sup>6</sup>m².m<sup>-3</sup>). The treatment efficiency reached 9.6kgN-NH<sub>4</sub>.m<sup>-3</sup>.d<sup>-1</sup> at 20°C and 4.9kgN-NH<sub>4</sub>.m<sup>-3</sup>.d<sup>-1</sup> at 13°C for hydraulic load of 644m³.m<sup>-2</sup>.d<sup>-1</sup>. Reduction of the ammonia amount ceased when the dissolved oxygen concentration was equal or inferior to 3mg0<sub>2</sub>.l<sup>-1</sup>. The nitrification's natural starting up phase lasted 42 days. This process could be reduced to 24 days by injection of commercial lyophilized bacteria into the filter.","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"Practical basis of nitrification in aquaculture waste-water","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1989,"MonPub":null,"DateUpdate":"2012-10-03","DateCreate":"2001-08-08","SecASFANote":null,"ConfID":null,"PeerRev":null,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":15103,"PubliDate":1989,"Pagination":"1115-1123","XtraPublOfAnaID":null,"ISBN":"90-71625-03-6","Volume":"1","Issue":null,"BRefMon":14854,"BRefMonRR":"<b>De Pauw, N. <i>et al.</i></b> (1989).
