Nchifukwa chiyani ma flocculant ndi ma coagulant amafunikira pochiza zimbudzi?

Flocculantsndipo ma coagulants amachita ntchito yofunika kwambiri pakukonza zimbudzi, zomwe zimathandiza kwambiri kuchotsa zinthu zolimba zomwe zapachikidwa, zinthu zachilengedwe, ndi zina zodetsa m'madzi otayidwa. Kufunika kwawo kuli pa luso lawo lokulitsa luso la njira zosiyanasiyana zoyeretsera, zomwe pamapeto pake zimapangitsa kuti pakhale madzi oyera omwe amatha kutayidwa bwino m'chilengedwe kapena kugwiritsidwanso ntchito pazinthu zosiyanasiyana.

Ma coagulants nthawi zambiri amatanthauza zinthu zopangidwa ndi aluminiyamu kapena ferric, monga aluminium sulfate, polyaluminum chloride ndi polyferric sulfate. Ma Flocculants amatanthauza ma organic polymers, monga polyacrylamide, poly(diallyldimethylammonium chloride), ndi zina zotero. Angagwiritsidwe ntchito payekhapayekha kapena kuphatikiza.

Kusonkhana kwa Tinthu Tating'onoting'ono: Zinyalala zimakhala ndi mitundu yosiyanasiyana ya tinthu tating'onoting'ono tomwe timapachikidwa, kuphatikizapo zinthu zachilengedwe, mabakiteriya, ndi zinthu zina zodetsa. Ma flocculants ndi ma coagulants zimathandiza kuti tinthu tating'onoting'ono timeneti tiphatikizidwe kukhala tinthu tating'onoting'ono tomwe timapanga ...Ma Coagulantamagwira ntchito pochepetsa mphamvu zoyipa pa tinthu tomwe timapachikidwa, zomwe zimawalola kuti azisonkhana pamodzi ndikupanga magulu akuluakulu. Koma ma flocculant, amalimbikitsa kupangika kwa tinthu tating'onoting'ono tomwe timapachikidwa mwa kulumikiza tinthu tating'onoting'ono kapena kuwapangitsa kuti agundane ndi kumamatirana.

Kukhazikika Bwino: Tinthu tating'onoting'ono tikakhala titasonkhana kukhala ma floc akuluakulu, timakhazikika mosavuta chifukwa cha mphamvu yokoka kapena njira zina zolekanitsira. Njira imeneyi, yomwe imadziwika kuti sedimentation, ndi gawo lofunika kwambiri pakukonza zimbudzi, chifukwa imalola kuchotsa zinthu zolimba zomwe zapachikidwa ndi zinyalala zina m'madzi otayidwa. Ma flocculant ndi ma coagulant amathandizira kukhazikika mwa kuwonjezera kukula ndi kuchuluka kwa ma floc, motero kufulumizitsa njira yokhazikitsira sedimentation ndikuwonjezera kuyera kwa madzi okonzedwa.

Kusefa Kowonjezereka: M'malo ena oyeretsera zinyalala, kusefa kumagwiritsidwa ntchito ngati njira yoyeretsera yachitatu kuti kuchotse zinthu zotsalira ndi zinyalala. Ma flocculant ndi ma coagulant amathandizira kusefa mwa kuthandizira kupanga tinthu tating'onoting'ono tomwe timakhala kosavuta kugwira ndikuchotsa m'madzi. Izi zimapangitsa kuti madzi asakhale oyera omwe amakwaniritsa miyezo yokhwima ndipo amatha kutulutsidwa kapena kugwiritsidwanso ntchito bwino pazinthu zosiyanasiyana monga kuthirira kapena ntchito zamafakitale.

Kupewa Kuipitsa: Mu njira zochizira monga kusefa kwa membrane ndi reverse osmosis, kuipitsa komwe kumachitika chifukwa cha kuchuluka kwa zinthu zolimba zomwe zimapachikidwa pa membrane zosefera kumatha kuchepetsa kwambiri magwiridwe antchito a dongosolo ndikuwonjezera zofunikira pakusamalira. Ma Flocculants ndi ma coagulants amathandizira kupewa kuipitsa mwa kulimbikitsa kuchotsa tinthu timeneti tisanafike pa gawo losefera. Izi zimathandiza kutalikitsa moyo wa membrane zosefera ndikusunga magwiridwe antchito nthawi zonse pakapita nthawi.

Ma flocculant ndi ma coagulant ndi zinthu zofunika kwambiri pakukonza zinyalala. Kutha kwawo kulimbikitsa kusonkhana kwa tinthu tating'onoting'ono, kukonza kukhazikika ndi kusefa, kuchepetsa kugwiritsa ntchito mankhwala, komanso kupewa kuipitsa zinthu kumapangitsa kuti zikhale zida zofunika kwambiri pakuwonetsetsa kuti ntchito zokonza zinyalala zikuyenda bwino komanso mosalekeza.
