Kev xaiv cov dej ntshiab uas tsim nyog yuav tsum muaj kev ntsuam xyuas zoo raws li qhov tshwj xeeb ntawm daim ntawv thov, cov dej yuav tsum tau muaj, muaj peev xwm tsim tau, thiab cov dej nyoos. Cov hauv qab no yog kev txiav txim siab tseem ceeb- ua qhov loj me:
Qhia meej txog qhov yuav tsum tau muaj dej zoo rau kev sim lossis kev tsim khoom. Kev siv sib txawv sib txawv rau cov qib dej ntshiab sib txawv, cais raws li GB / T 6682-2008 tus qauv:
Qib I (Ultrapure Water, 18.2 MΩ·cm): Siv rau siab -kev tsom xam thiab kev tshawb fawb txog lub neej xws li HPLC, LC-MS, kab lis kev cai ntawm tes, thiab PCR.
Grade II (EDI Pure Water, >5 MΩ·cm): Tsim nyog rau cov kev sim niaj hnub xws li kev npaj tsis muaj dej, dej rau biochemical analyzers, thiab kab lis kev cai microbial.
Qib III (RO Dej): Siv rau cov kev siv yooj yim xws li ntxuav iav, da dej, thiab autoclaves.
Txheeb xyuas qhov sib haum xeeb ntawm cov khoom noj khoom haus dej thiab pretreatment system.
Qhov zoo ntawm cov dej nyoos ncaj qha cuam tshuam rau kev teeb tsa thiab kev ua neej nyob:
Tank dej raws li dej pub: Ib qho RO rov qab osmosis membrane yuav tsum tau siv los ua thawj chav purification kom tshem tawm tau zoo tshaj 95% ntawm ions, organic teeb meem, thiab kab mob.
Cov dej ntshiab / dej distilled raws li cov dej pub: Ib qho dej ntshiab huv (xws li Milli-Q® IQ 7000) tuaj yeem xaiv, muab qhov loj me thiab ua haujlwm siab.
Cov dej pub tshwj xeeb (siab hardness, siab fluoride, siab chlorine): Customized pretreatment modules yuav tsum tau, xws li softening, defluoridation, los yog sib sib zog nqus activated carbon adsorption, kom tsis txhob membrane fouling thiab system tsis ua hauj lwm.
