The denitrification rate increased up to a maximal value of 1.3 gNO3-N m-2 day-1 with increasing nitrogen loading rate. Kinetic analysis of the system confirmed a half-order denitrification kinetic region in the NOx-N concentration range from 0.25 mg L-1 to 16 mg L-1, with the half-order reaction coefficient k1ž2 of 0.35 g0.5 m-0.5 day-1 when the carbon source was in excess. Under the experimental conditions, drinking water quality was achieved at a nitrogen loading lower than 1.9 gNO3-N m-2 day-1 with an influent COD/N ratio of 3.7 if acetate was used as the carbon source. The system is fairly robustč it can be operated in a simple manner at low hydraulic loadings without recirculation flow and without backwashing"},{"@xml:lang":"sl","#text":"Preučevali smo delovanje laboratorijskega pilotnega reaktorja s pritrjeno biomaso za denitrifikacijo podtalnice. Specifičen nosilec biomase, ki smo uporabili v reaktorju, smo razvili na Kemijskem inštitutu, Ljubljana. V koncentracijskem območju NOx-N od 0.25 mg L-1 do 16 mg L-1 je reaktor deloval v režimu kinetike polovičnega reda s konstanto hitrosti k1/2 = 0.35 g0.5 m-0.5dan-1 (0.058 g0.5 L-0.5 dan-1). Predpisane vrednost parametrov za pitno vodo smo dosegli pri obremenitvi nižji od 1.9 gNO3-N.m-2.dan-1 (0.31 g0.5 L-0.5 dan-1). Optimalno razmerje KPK/N v toku je 3,7, če smo kot zunanji vir ogljika uporabili acetat. Delovanje rektorja s specifičnim nosilcem biomase je enostavno, povratno spiranje ni potrebno, ker se tudi pri nizkih obtočnih hitrostih sloj nosilca ni mašil z odvečno biomaso"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-MCLT7CBW","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-MCLT7CBW"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-MCLT7CBW/93da47a0-6894-4f6b-acc6-aa7af38a4d8f/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Slovensko kemijsko društvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-MCLT7CBW/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-MCLT7CBW"}}}}
