Povzetek


V članku predstavljamo primer razkuževanja vode z ultravijolično (UV) svetlobo v recirkulacijskem akvakulturnem sistemu reje jesetrov za prirejo iker, namenjenih za kaviar. Med metodami razkuževanja vode pri gojenju rib v zaprtih akvakulturnih sistemih reje so najučinkovitejši pristopi z uporabo ozoniranja ali UV sevanja v kombinaciji z drugimi metodami. Nepravilna uporaba ozoniranja za razkuževanje vode lahko povzroči nastanek prevelikih koncentracij ozona, ki lahko negativno vplivajo na zdravje rib in škodujejo okolju in osebju v ribogojnici. Predstavljamo primer razkuževanja vode, ki temelji na uporabi UV svetlobe. Preliminarni rezultati so pokazali, da razkuževanje vode z metodo filtracije in UV sterilizacije zagotavlja učinkovito inaktivacijo mikroorganizmov v bazenu za gojenje rib, saj skupno število mikrobov, skupno število koliformnih bakterij in E. coli (CFU/m3) ni preseglo priporočenih vrednosti. Opisani sistem proizvaja jakost UV sevanja 180 W/m2, kar ob uporabi 480 W kvarčnih UV žarnic zagotavlja bakteriološko čistost vode za bazen prostornine 300 m3.
