Ka palena o ka hoohana
ʻO ka ʻōnaehana disinfection wai UV ʻAʻole i manaʻo ʻia no ka mālama ʻana i ka wai i ʻike maopopo ʻia a i ʻole ke kumu i manaʻo ʻia, e like me ka ʻōpala maka, ʻaʻole hoʻi i manaʻo ʻia ka ʻāpana e hoʻololi i ka wai ʻino i ka wai inu palekana microbiologically.
ʻAno wai (i loko)
He kuleana koʻikoʻi ka maikaʻi o ka wai i ka lawe ʻana i nā kukuna UV germicidal.Manaʻo ʻia ʻaʻole e ʻoi aku ka wai ma hope o nā pae kiʻekiʻe.
Nā pae hoʻopaʻa kiʻekiʻe loa (mea nui loa)
Hao | ≤0.3ppm(0.3mg/L) |
ʻoʻoleʻa | ≤7gpg(120mg/L) |
ʻOhuehue | <5NTU |
Manganese | ≤0.05ppm(0.05mg/L) |
Paʻa paʻa ʻia | ≤10ppm(10mg/l) |
Ka hoʻouna ʻana o UV | ≥750‰ |
Hiki ke hoʻokō ʻia ka mālama pono ʻana i ka wai me nā pae hoʻonaʻauao kiʻekiʻe ma mua o ka mea i helu ʻia ma luna, akā makemake paha i nā hana hou e hoʻomaikaʻi ai i ka maikaʻi o ka wai i nā pae hiki ke mālama ʻia.Inā, no kekahi kumu, ua manaʻo ʻia ʻaʻole ʻoluʻolu ka lawe ʻana o UV, e hoʻopili i ka hale hana.
Loʻihi hawewe UV (nm)
E make ana nā kinikini ma ka UVC(200-280mm) irradiation.253.7nm laina spectral o ka haʻahaʻa haʻahaʻa mercury kukui i kiʻekiʻe bactericidal hopena a concentrates oi aku mamua o 900‰ ikehu puka o haʻahaʻa-press mercury UV kukui.
Uwila
Hoʻokumu nā ʻāpana i kahi ʻano UV o ka liʻiliʻi he 30,000microwatt-kekona ma ke kenimika square (μW-s/cm.2), ʻoiai i ka pau ʻana o ke ola kukui (EOL), ʻoi aku ka nui ma mua o ka lawa ʻana e luku i ka hapa nui o nā microorganisms wai, e like me ka bacteria, yeasts, algae etc.
ʻO DOSAGE ka huahana o ka ikaika a me ka manawa manawa = ka ikaika * manawa = micro watt / cm2*manawa=microwatt-kekona no ke kenimika huinaha (μW-s/cm2) Nānā:1000μW-s/cm2=1mj/cm2(milli-joule/cm2) |
Ma ke ʻano he alakaʻi maʻamau, eia kekahi mau helu hoʻoili UV maʻamau (UVT)
Nā lako wai o ke kūlanakauhale | 850-980‰ |
ʻO ka wai de-ionized a i ʻole Reverse Osmosis | 950-980‰ |
Ka wai o luna (nā loko, nā muliwai, a me nā mea ʻē aʻe) | 700-900‰ |
Ka wai honua (punawai) | 900-950‰ |
Nā wai ʻē aʻe | 10-990‰ |
