Aluminium Sulfate rau Pas Dej
Taw qhia
Aluminium Sulfate, feem ntau hu ua alum, yog cov tshuaj kho dej ntau yam siv dav hauv kev saib xyuas pas dej ua ke los txhim kho cov dej zoo thiab pom tseeb. Peb Aluminium Sulfate yog cov khoom lag luam qib siab tsim los daws cov teeb meem dej ntau yam, ua kom muaj kev huv thiab caw ib puag ncig ua luam dej.

Cov yam ntxwv tseem ceeb
Kev piav qhia dej:
Aluminium Sulfate yog renowned rau nws tshwj xeeb dej clarifying zog. Thaum ntxiv rau cov dej hauv pas dej, nws tsim cov gelatinous aluminium hydroxide precipitate uas khi cov khoom zoo thiab cov impurities, txhawb nqa lawv yooj yim tshem tawm los ntawm kev pom. Qhov no ua rau cov dej ntshiab ntshiab uas txhim kho qhov zoo nkauj ntawm lub pas dej.
Kev cai pH:
Peb Aluminium Sulfate ua raws li pH regulator, pab kom stabilize thiab tswj cov qib pH zoo nyob rau hauv lub pas dej ua ke. Kev sib npaug pH zoo yog qhov tseem ceeb rau kev tiv thaiv corrosion ntawm cov khoom siv hauv pas dej ua ke, ua kom cov khoom siv tshuaj tua kab mob zoo, thiab muab kev ua luam dej zoo.
Kev kho Alkalinity:
Cov khoom no pab tswj cov qib alkalinity hauv cov dej hauv pas dej. Los ntawm kev ua kom zoo alkalinity, Aluminium Sulfate pab tiv thaiv kev hloov pauv hauv pH, tswj qhov chaw ruaj khov thiab sib npaug rau cov neeg ua luam dej thiab cov khoom siv hauv pas dej.
Flocculation:
Aluminium Sulfate yog ib qho zoo heev flocculating tus neeg saib xyuas, yooj yim rau kev sib sau ntawm cov khoom me me rau hauv pawg loj. Cov khoom loj dua no yooj yim dua los lim tawm, txhim kho kev ua haujlwm ntawm lub pas dej ua ke pom thiab txo cov load ntawm lub pas dej da dej.
Daim ntawv thov
Txhawm rau siv Aluminium Sulfate, ua raws li cov kauj ruam yooj yim no:
Dissolve hauv dej:
Dissolve qhov pom zoo ntawm Aluminium Sulfate hauv ib lub thoob dej. Do cov tshuaj kom ntseeg tau tias kev sib cais tiav.
Txawm Distribution:
Ncuav cov tshuaj yaj kom sib npaug thoob plaws lub pas dej ua ke, faib nws li uniformly li sai tau.
Lim:
Khiav lub pas dej pom qhov system rau lub sijhawm txaus kom tso cai rau Aluminium Sulfate kom cuam tshuam nrog impurities thiab precipitate lawv.
Kev saib xyuas tsis tu ncua:
Tsis tu ncua saib pH thiab alkalinity qib kom ntseeg tau tias lawv nyob hauv qhov pom zoo. Kho raws li qhov tsim nyog.
Ceev faj:
Nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li cov lus pom zoo thiab daim ntawv thov cov lus qhia muab rau ntawm daim ntawv lo khoom. Kev siv tshuaj ntau dhau tuaj yeem ua rau muaj kev cuam tshuam tsis zoo, thiab kev siv tshuaj ntau dhau yuav ua rau kev kho dej tsis zoo.
Peb Aluminium Sulfate yog ib qho kev txhim khu kev qha rau kev tswj cov dej hauv pas dej ua ke. Nrog nws cov txiaj ntsig ntau yam, suav nrog kev nthuav dav dej, pH kev tswj hwm, kev hloov kho alkalinity, flocculation, thiab phosphate tswj, nws ua kom muaj kev nyab xeeb, xis nyob, thiab pom kev ua luam dej. Cia siab rau peb cov qib zoo Aluminium Sulfate kom koj lub pas dej ntshiab thiab caw.
