Chii chinonzi Ultraviolet Radiation
Chimiro chinozivikanwa zvikuru chemwaranzi yeUV chiedza chezuva, icho chinobudisa marudzi makuru matatu emiranzi yeUV, UVA (315-400nm), UVB (280-315nm), uye UVC (ipfupi kupfuura 280 nm).Iyo UV-C bhendi yeultraviolet mwaranzi ine wavelength yakatenderedza 260nm, iyo yakaonekwa seyakanyanya kushanda mwaranzi yekuvharisa, inoshandiswa kuvharisa mvura.
Kushanda Nheyo
Iyo sterilizer inobatanidza hunyanzvi hunyanzvi kubva kuoptics, microbiology, chemistry, zvemagetsi, mechanics uye hydromechanics, ichigadzira yakakwira uye inoshanda UV-C ray yekuvhenekera mvura inoyerera.Mabhakitiriya nemavhairasi ari mumvura anoparadzwa nehuwandu hwakakwana hweUV-C ray (wavelength 253.7nm).Sezvo DNA uye chimiro chemasero zvakaparadzwa, kuberekwa patsva kwesero kunorambidzwa.Mvura inouraya utachiona uye kucheneswa kunozadzisa zvizere.Uyezve, iyo UV ray ine wavelength ye185nm inogadzira ma hydrogen radicals kuti oxidize ma organic molecules kuCO2 neH2O, uye TOC iri mumvura inobviswa.

● Haichinje kuravira, pH, kana zvimwe zvinhu zvemvura
● Haiburitse mishonga yekuuraya utachiona kubva kune hutano hwakagadzirwa
● Hapana ngozi yekuwedzera uye inogona kugadziriswa nyore nyore kuchinja kuyerera kwemvura kana zvinhu zvemvura
● Inoshanda kurwisa marudzi ose eutachiona, kusanganisira mabhakitiriya, mavhairasi, fungi, uye protozoa
● Inoderedza makemikari anodiwa
