Hibridni membranski reaktorski sistem: čiščenje z nitratnimi ioni onesnažene podtalniceRavnjak, Matjaž ; Vrtovšek, Janez ; Pintar, AlbinTehnologija membranskih bioreaktorjev (MBR) se je že močno uveljavila na področju biološkega čiščenja komunalnih odpadnih vod [1]. Postopek ločevanja aktivnega blata od obdelane vode z membranami ... omogoča, da je v iztoku iz MBR sistemov, v primerjavi z iztokom iz konvencionalnih bioloških čistilnih naprav, občutno nižja koncentracija mikroorganizmov. Zaradi boljše mikrobiološke kakovosti obdelane vode je MBR tehnologija postala zanimiva tudi za področje čiščenja onesnažene podtalnice, kjer so se do sedaj uporabi bioloških procesov večinoma izogibali [2]. V MBR napravah lahko vzdržujemo visoke koncentracije aktivnega blata, kar poveča intenziteto bioloških postopkov, vendar hkrati negativno vpliva na pretočnost membran zaradi mašenja (fouling) z nabiranjem plasti mikroorganizmov in njihovih izločkov na površini in v porah membran. Zato so v zadnjem času začeli razvijati MBR sisteme (hibridni ali biofilm MBR sistemi), ki temeljijo na delovanju mikroorganizmov, ki so pritrjeni na nosilnem materialu. S tem se ohrani visoka intenziteta bioloških procesov, hkrati pa se v obdelani vodi, ki prihaja v proces separacije z membranami, nahaja le zelo nizka koncentracija dispergiranih mikroorganizmov. Rezultati kažejo na to, da je mogoče z uporabo nosilcev v membranskem bioreaktorju doseči skoraj 100% odstranjevanje nitratnih ionov.Source: Zbornik referatov : [simpozij z mednarodno udeležbo] (Str. 51-58)Type of material - conference contribution ; adult, seriousPublish date - 2011Language - slovenianCOBISS.SI-ID - 4832538
