As in fresh-water systems, biofilm kinetics could be described accurately by the 1/2-order / 0-order kinetic model. However, sea-water systems need a much longer start-up period in which nitrite accumulates. Thereby, the maximum nitrification capacity is considerably lower than in fresh-water systems; at 24°C a maximum 0-order ammonia removal rate of 0.28 g m<sup>−2</sup> d<sup>−1</sup> NH<sub>4</sub>-N is observed, versus 0.69 g m<sup>−2</sup> d<sup>−1</sup> NH<sub>4</sub>-N in comparable fresh-water systems. Adaptation of a fresh-water biofilter to higher salinities was found to be possible, providing an effective tool for a shorter start-up period of a sea-water system. Nitrification rates were obtained which allow a rational design of intensive recirculating sea-water fish culture systems.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Fixed film nitrification characteristics in sea water recirculating fish culture systems","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":1990,"MonPub":null,"DateUpdate":"2009-04-30","DateCreate":"2009-04-30","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":134622,"PubliDate":1990,"Pagination":"133-143","XtraPublOfAnaID":null,"ISBN":null,"Volume":"87","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42190,"SerRR":"Aquaculture.
