Dab tsi yog qhov sib txawv ntawm kev coagulation thiab flocculation?

Coagulation thiab flocculation yog ob qho txheej txheem tseem ceeb siv nyob rau hauv kev kho dej kom tshem tawm impurities thiab hais los ntawm dej. Thaum lawv muaj feem xyuam thiab feem ntau siv ua kev sib txuas, lawv ua haujlwm sib txawv me ntsis:

Coagulation:

Coagulation yog theem pib hauv kev kho cov dej, qhov twg coeagulants yog ntxiv rau dej. Cov feem ntau yog cov coagulants yogAluminium Sulfate(Alum) thiab ferric chloride. Cov tshuaj no tau ntxiv rau txoj kev ua kom muaj kev them nqi rau cov khoom (colloids) tam sim no hauv dej.

Cov co coagulants ua haujlwm los ntawm nruab nrab cov nqi hluav taws xob rau cov khoom no. Cov nplais hauv cov dej feem ntau muaj tus nqi tsis zoo, thiab cov co coavulants qhia cov nqi ntawm ions. Qhov nruab nrab no txo ​​cov electrostatic repulsion ntawm cov me me, tso cai rau lawv kom lawv los ze dua ua ke.

Raws li qhov kev cuam tshuam ntawm kev sib cais, cov me me pib sib tsoo ua ke, tsim cov ntawv loj dua, cov khoom uas muaj flocs. Cov flocs no tseem tsis tau loj txaus los khom ntawm cov dej los ntawm kev sib tsoo ntawm lub ntiajteb txawj nqus, tab sis lawv tau yooj yim dua rau cov txheej txheem kho vaj tse tom ntej.

Flocculation:

Flocculation ua raws li kev sib cais hauv cov txheej txheem kev kho dej. Nws cuam tshuam tau nplawm los yog agitating dej los txhawb kom cov froc me me txhawm rau sib tsoo thiab sib txuas ua cov flocs loj.

Flocculation pab txhawb kev tsim kom muaj kev loj dua, denser flocs uas tuaj yeem daws cov dej zoo dua ntawm cov dej. Cov khaub thuas loj no yooj yim dua los cais los ntawm cov dej kho.

Thaum lub sij hawm flocculation txheej txheem, cov tshuaj ntxiv hu ua cov flocculusts yuav raug ntxiv ntxiv rau kev pab hauv agglomeration ntawm flocs. Cov flocculants muaj polymers.

Hauv cov ntsiab lus, coagulation yog cov txheej txheem ntawm txoj kev siv tshuaj lom neeg nyob hauv dej los ntawm nruab nrab lawv cov nqi, thaum flocculation yog cov txheej txheem ntawm kev nqa cov noCov khoom siv tau ua ke ua ke los tsim cov flocs loj dua. Ua ke, sib xyaw ua ke thiab flocculation pab qhia kom yooj yim rau kev tshem tawm cov nplais thiab cov txheej txheem dediment thiab pom hauv cov nroj tsuag dej.

Peb tuaj yeem muab koj cov flocculant, coagulant thiab lwm yam tshuaj lom neeg dej koj xav tau raws li koj cov dej ua tau zoo thiab xav tau. Email rau cov lus pub dawb (sales@yuncangchemical.com )
