Aluminium Sulfate Kev Muag Khoom
Khoom Txheej Txheem
Aluminium sulfate, nrog cov tshuaj feem ntau yog siv tshuaj siv tshuaj ntsuab al2 (so4) 3, yog ib qho kev tsim khoom tseem ceeb hauv cov dej, tawv nqaij, khoom noj khoom haus thiab lwm daim teb. Nws muaj cov khoom siv sib xyaw ua kom muaj zog thiab cov khoom kom zoo thiab tuaj yeem tshem tawm cov khib nyiab tshem tawm, cov xim thiab impurities hauv dej. Nws yog ntau-ua haujlwm thiab cov neeg saib xyuas dej ua haujlwm zoo.

Daim ntawv thov tseem ceeb tseem ceeb
Kev kho cov dej:Siv los ntxuav cov kais dej thiab kev siv dej tsaws chaw, tshem tawm cov khib nyiab, xim thiab impurities, thiab txhim kho cov dej zoo.
Cov Ntawv Raug:Siv los ua cov muab tub lim thiab cov neeg sawv cev los txhim kho lub zog thiab cov ntawv ci.
Tawv Ua:Siv nyob rau hauv cov txheej txheem tanning ntawm tawv los txhim kho nws cov qauv thiab xim.
Kev Lag Luam Khoom Noj:Raws li ib feem ntawm cov coagulants thiab flasing cov neeg sawv cev, nws yog dav siv hauv cov zaub mov.
Kws Kev Lag Luam:Siv nyob rau hauv qee qhov kev tawm tsam thaum npaj thiab ua khoom ntawm cov kws tshuaj.
Cia thiab ceev faj
Aluminium sulfate yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav kom deb ntawm kev tshav ntuj ncaj qha.
Zam kev sib xyaw nrog cov tshuaj acidic kom tsis txhob cuam tshuam kev ua haujlwm.
