Kodi Flocculant imagwira ntchito bwanji poyeretsa madzi?

Flocculantsamathandizira kwambiri pakuyeretsa madzi pothandizira kuchotsa tinthu tating'onoting'ono tomwe timayimitsidwa ndi ma colloid m'madzi.Njirayi imaphatikizapo kupanga ma flocs akuluakulu omwe amatha kukhazikika kapena kuchotsedwa mosavuta kudzera mu kusefera.Umu ndi momwe ma flocculants amagwirira ntchito pochiza madzi: 

Flocculants ndi mankhwala omwe amawonjezedwa m'madzi kuti athandizire kuphatikizika kwa tinthu tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tomwe timatchedwa flocs.

Mitundu yodziwika bwino ya ma flocculants imaphatikizapo inorganic coagulants ngatiPolymeric Aluminium Chloride(PAC) ndi ferric chloride, komanso ma organic polymeric flocculants omwe amatha kukhala ma polima opangira monga polyacrylamide kapena zinthu zachilengedwe monga chitosan.

Coagulation:

Pamaso flocculation, ndi coagulant akhoza kuwonjezeredwa destabilize colloidal particles.Ma coagulants amachepetsa mphamvu zamagetsi pa tinthu tating'onoting'ono, kuwalola kuti asonkhane.

Ma coagulants odziwika bwino amaphatikizapo polymeric aluminium chloride, aluminium sulphate (alum) ndi ferric chloride.

Flocculation:

Ma Flocculants amawonjezeredwa pambuyo pa coagulation kulimbikitsa mapangidwe a magulu akuluakulu.

Mankhwalawa amalumikizana ndi tinthu tating'onoting'ono tating'onoting'ono, zomwe zimapangitsa kuti zisonkhane ndikupanga mwachangu magulu akuluakulu, owoneka.

Mapangidwe a Floc:

Njira ya flocculation imapangitsa kuti pakhale magulu akuluakulu komanso olemera omwe amakhazikika mofulumira chifukwa cha kuchuluka kwa misa.

Kupanga kwa Floc kumathandizanso kutsekereza zonyansa, kuphatikiza zolimba zoyimitsidwa, mabakiteriya, ndi zonyansa zina.

Kukhazikitsa ndi Kufotokozera:

Ziphuphu zikapangidwa, madzi amaloledwa kukhazikika mu beseni la sedimentation.

Pakukhazikika, flocs imakhazikika pansi, ndikusiya madzi omveka pamwamba.

Sefa:

Kuti ayeretsedwenso, madzi omveka bwino amatha kusefedwa kuti achotse tinthu tating'onoting'ono tomwe tatsala pang'ono kukhazikika.

Kupha tizilombo toyambitsa matenda:

Pambuyo pa flocculation, kukhazikika, ndi kusefera, madzi nthawi zambiri amathiridwa ndi mankhwala ophera tizilombo toyambitsa matenda monga chlorine kuti athetse tizilombo totsalira ndikuonetsetsa kuti madzi ali otetezeka.

Mwachidule, flocculants ntchito neutralizing mlandu wa inaimitsidwa particles, kulimbikitsa aggregation wa tinthu tating'onoting'ono, kupanga zazikulu flocs kukhazikika kapena mosavuta kuchotsedwa, zikubweretsa bwino ndi oyera madzi.
