Aia ka ma'i bacteria a me ka ma'i ma'i ma ka lewa, ka wai a me ka lepo, a ma kahi o ka ili a pau o ka ai, na mea kanu a me na holoholona.ʻAʻole hōʻeha ka hapa nui o ka bacteria a me ka virus i ke kino kanaka.Eia naʻe, hoʻololi kekahi o lākou i mea e hōʻino ai i ke kino o ke kino, e hoʻoweliweli ana i ke olakino o ke kanaka.
He aha ka Ultraviolet Radiation
ʻO ke ʻano maʻamau o ka radiation UV ka lā, kahi e hoʻopuka ai i ʻekolu ʻano nui o nā kukuna UV, UVA (315-400nm), UVB (280-315nm), a me UVC (ʻoi aku ka pōkole ma mua o 280 nm).ʻO ka hui UV-C o ka hihi ultraviolet me ka lōʻihi o ka nalu ma kahi o 260nm, i ʻike ʻia ʻo ia ka hihi kūpono loa no ka sterilizing, hoʻohana ʻia no ka sterilization wai.
Kumu Hana
Hoʻohui ka sterilizer i nā ʻenehana holoʻokoʻa mai ka optics, microbiology, chemistry, electronics, mechanics and hydromechanics, e hana ana i ka hihi UV-C ikaika kiʻekiʻe a maikaʻi e hoʻomālamalama i ka wai kahe.Hoʻopau ʻia nā maʻi bacteria a me nā maʻi i loko o ka wai e ka nui o ka hihi UV-C (ka lōʻihi o ka nalu 253.7nm).I ka luku ʻia ʻana o ka DNA a me ke ʻano o nā cell, ua kāohi ʻia ka hana hou ʻana o ka cell.Hoʻopau loa ka hoʻomaʻemaʻe wai a me ka hoʻomaʻemaʻe.Eia kekahi, ʻo ka hihi UV me ka hawewe nalu o 185nm e hoʻopuka i nā radical hydrogen e hoʻoneʻe i nā molekala organik i CO2 a me H2O, a ua hoʻopau ʻia ka TOC i ka wai.
ʻO nā pono o ka Disinfection a me ka Sterilization o UV-C
● ʻAʻole hoʻololi i ka ʻono, ka pH, a i ʻole nā waiwai ʻē aʻe o ka wai
● ʻAʻole ia e hoʻopuka i nā huahana disinfection o ke olakino pili i hana ʻia
● ʻAʻohe pilikia o ka hana nui a hiki ke hoʻoponopono maʻalahi i ka hoʻololi ʻana i ke kahe wai a i ʻole nā waiwai wai
● Hiki ke kū'ē i nā ʻano microorganism a pau, e like me ka bacteria, nā maʻi maʻi, nā fungi, a me nā protozoa
● Hoʻemi i nā kemika e pono ai
● Palekana a pili kaiapuni
Ka Nui a me ka Unite o Ultraviolet Radiation
Nā Waiwai Irradiance o kā mākou Lako
Pākuʻi Radiation
Pono nā microorganism a pau e hoʻopau ʻia.
Nt /No = exp.(-kEefft)………………1
No laila ma Nt /N o = --kEefft…………2
● ʻO Nt ka helu o nā germs i ka manawa t
● ʻAʻole ka helu o nā germs ma mua o ka ʻike ʻana
● k he helu helu mau ma muli o ka ʻano
● ʻO Eefft ka irradiance kūpono ma W/m2
ʻO ka huahana Eefft i kapa ʻia ʻo ka hopena kūpono
Hōʻike ʻia ka Heff ma Ws/m2 a me J/m2
No ka 90% make ka hoohalike 2 lilo
2.303 = kHeff
Hāʻawi ʻia kekahi mau hōʻailona k waiwai ma ka papa 2, kahi e ʻike ʻia ai ke ʻano like ʻole mai ka 0.2 m2/J virus a me ka bacteria, i ka 2.10-3 no nā spores mold a me 8.10-4 no nā algae.Me ka hoʻohana ʻana i nā hoʻohālikelike ma luna, hiki ke hana ʻia ka helu 14 e hōʻike ana i nā ola a i ʻole pepehi % versus dose.
