Aluminium sulfate rau cov pas dej
Lub hauv paus rau phau ntawv
Aluminium sulfate, feem ntau hu ua alum, yog ib qho tshuaj lom neeg siv tshuaj ntau yam dav siv hauv pas dej zoo thiab kev pom tseeb. Peb cov sulfate txhuas yog cov khoom lag luam uas tsim nyog tsim los kom muaj ntau yam dej ntsig txog cov dej muaj feem xyuam nrog dej, kom muaj kev huv si thiab hloov chaw nyob.

Cov Nta Tseem Ceeb
Dej tshab:
Aluminium Sulfate muaj npe rau nws cov dej tshwj xeeb kom meej cov yam ntxwv. Thaum ntxiv mus rau pas dej dej, nws tsim cov gelatinous aluminium hydroxide precketically uas khi zoo, txhawb nqa lawv yooj yim los ntawm kev lim dej. Qhov no tshwm sim hauv cov dej muaj roj crystal uas txhim kho qhov kev ua kom zoo nkauj tag nrho ntawm lub pas dej.
PHO kev cai:
Peb cov txheej txheem sulfate ua raws li PHICULATOR, pab kom txav chaw thiab tswj kav hauv pas dej hauv pas dej. Tsim nyog sau ntawv yog qhov tseem ceeb rau kev tiv thaiv corrosion ntawm cov khoom siv pas dej, kom ua rau cov hauj lwm zoo ntawm cov dej khov, thiab muab kev ua luam dej ua luam dej.
Alkalinity Kho:
Cov khoom lag luam pab no hauv kev tswj cov qib Alkalinity hauv pas dej dej. Los ntawm kev faib cov alkalinity, txhuas sulfate pab tsis txhob muaj kev sib cais hauv Ph, tswj hwm ib puag ncig ua si ruaj khov thiab muaj khoom noj.
Flocculation:
Aluminium sulfate yog ib qho zoo tshaj plaws flocculating tus neeg sawv cev, pab txhawb kev sib sau ua ke ntawm cov pob txha me me. Cov khoom loj no tau yooj yim rau lim tawm, txhim kho kev ua haujlwm ntawm cov khoom siv sau ua ke thiab txo lub nra ntawm cov pas dej twj tso kua mis.
Cov Ntawv Thov
Txhawm rau siv txhuas sulfate, ua raws cov kauj ruam yooj yim no:
Yaj hauv dej:
Daws cov kev pom zoo ntawm txhuas sulfate hauv ib lub thoob dej. Do kev daws teeb meem los xyuas kom ua tiav kev sib cais.
Txawm faib:
Ncuav txoj kev yaj ntshai ntawm cov pas dej ua ke, faib nws li uniformly li sai tau.
Pom:
Khiav lub pas dej ua haujlwm rau lub sijhawm ua kom muaj peev xwm ua kom muaj qhov txhuas ua kom zoo nrog impurities thiab precipitate lawv.
Kev Tshuaj Xyuas Li Qub:
Nquag ntsuam xyuas PH thiab alkalinity qib kom ntseeg tau tias lawv nyob hauv cov kev pom zoo. Kho raws li qhov tsim nyog.
Ceev faj:
Nws yog qhov tseem ceeb kom ua raws li cov kev pom zoo muab thiab cov lus qhia thov muab rau ntawm cov ntawv cim khoom. Overdosing tej zaum yuav ua rau cov teebmeem uas tsis xav tau, thiab underdosing tej zaum yuav ua rau muaj kev kho dej tsis muaj txiaj ntsig.
Peb cov sulfate txhuas yog qhov daws kev txhim khu kev qha kom tswj cov dej phristine pas dej. Nrog nws cov txiaj ntsig multifaceted, suav nrog kev ua kom tiav, phosphate kev hloov kho, nws ua rau muaj kev nyab xeeb, xis nyob, thiab visualual thov ua luam dej. Ntseeg peb tus nqi-qib aluminium sulfate kom koj da dej ntshiab thiab kev caw.
