Thaum yuav khoomPolyaluminium Chloride(PAC), cov coagulant siv dav hauv cov txheej txheem kho dej, ntau qhov ntsuas tseem ceeb yuav tsum raug ntsuas kom ntseeg tau tias cov khoom ua tau raws li cov qauv xav tau thiab tsim nyog rau nws daim ntawv thov. Hauv qab no yog cov cim tseem ceeb los tsom rau:
1. Cov ntsiab lus txhuas
Cov khoom tseem ceeb hauv PAC yog txhuas. Kev ua tau zoo ntawm PAC ua cov coagulant feem ntau nyob ntawm qhov concentration ntawm txhuas. Feem ntau, cov ntsiab lus txhuas hauv PAC tau qhia raws li feem pua ntawm Al2O3. Cov khoom zoo PAC feem ntau muaj li ntawm 28% mus rau 30% Al2O3. Cov ntsiab lus ntawm aluminium yuav tsum txaus los xyuas kom meej coagulation zoo yam tsis muaj kev siv ntau dhau, uas tuaj yeem ua rau kev lag luam tsis muaj txiaj ntsig thiab muaj peev xwm cuam tshuam rau cov dej tsis zoo.
2. Lub hauv paus
Basicity yog ib qho kev ntsuas ntawm qib ntawm hydrolysis ntawm txhuas hom hauv PAC thiab qhia raws li feem pua. Nws qhia qhov piv ntawm hydroxide rau txhuas ions hauv cov tshuaj. PAC nrog lub hauv paus ntawm 40% mus rau 90% feem ntau yog nyiam rau kev siv dej. Lub hauv paus siab dua feem ntau txhais tau tias muaj txiaj ntsig zoo dua coagulation tab sis yuav tsum sib npaug rau cov kev cai tshwj xeeb ntawm cov txheej txheem kho dej kom tsis txhob muaj kev kho ntau dhau los yog qis dua.
4. Qib impurity
Lub xub ntiag ntawm impurities xws li hnyav hlau (xws li, txhuas, cadmium) yuav tsum tsawg heev. Cov impurities no tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv thiab cuam tshuam rau kev ua haujlwm ntawm PAC. High-purity PAC yuav muaj tsawg heev ntawm cov kab mob no. Cov ntawv qhia tshwj xeeb uas muab los ntawm cov tuam txhab tsim khoom yuav tsum suav nrog cov ntaub ntawv ntawm qhov siab tshaj plaws tso cai rau cov impurities no.
6. Daim ntawv (khoom los yog kua)
PACmuaj nyob rau hauv ob qho tib si khoom (hmoov lossis granules) thiab cov ntaub ntawv ua kua. Kev xaiv ntawm cov ntaub ntawv khoom thiab cov kua yog nyob ntawm cov kev cai tshwj xeeb ntawm cov chaw kho mob, suav nrog cov chaw cia khoom, cov khoom siv tshuaj, thiab kev yooj yim ntawm kev tuav. Liquid PAC feem ntau nyiam rau nws txoj kev yooj yim ntawm kev siv thiab kev tawg sai, qhov PAC cov khoom yuav raug xaiv rau lub sijhawm ntev cia thiab kev thauj mus los zoo. Txawm li cas los xij, lub txee lub neej ntawm cov kua yog luv luv, yog li nws tsis pom zoo kom yuav cov kua ncaj qha rau kev khaws cia. Nws raug nquahu kom yuav khoom thiab ua rau koj tus kheej raws li qhov sib piv.
7. Lub neej txee thiab ruaj khov
Kev ruaj ntseg ntawm PAC dhau lub sijhawm cuam tshuam rau nws txoj haujlwm. High-quality PAC yuav tsum muaj lub neej txee ruaj khov, tswj nws cov khoom thiab ua haujlwm tau zoo nyob rau lub sijhawm ntev. Cia tej yam kev mob, xws li kub thiab raug rau huab cua, tuaj yeem cuam tshuam qhov kev ruaj ntseg, yog li PAC yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav hauv cov ntim ntim kom khaws nws zoo.
8. Nqi-zoo
Ntxiv nrog rau cov khoom lag luam zoo, nws tseem yuav tsum tau xav txog cov nqi-zoo ntawm kev yuav khoom. Sib piv cov nqi, ntim khoom, kev thauj mus los, thiab lwm yam ntawm cov neeg muag khoom sib txawv kom pom cov khoom uas tsim nyog tus nqi.
Hauv cov ntsiab lus, thaum yuav polyaluminium chloride, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov ntsiab lus ntawm txhuas, qhov tseem ceeb, pH tus nqi, qib impurity, solubility, daim ntawv, txee lub neej, nqi-zoo, thiab kev tswj xyuas. Cov ntsuas no sib sau ua ke txiav txim siab qhov tsim nyog thiab kev ua haujlwm ntawm PAC rau ntau daim ntawv thov kev kho dej.
