Kodi ma flocculants odziwika bwino a cationic ndi ati?

Kusamalira madzi ndi gawo lofunika kwambiri pa kayendetsedwe ka chilengedwe, kuonetsetsa kuti madzi ndi otetezeka kugwiritsidwa ntchito komanso kugwiritsidwa ntchito m'mafakitale. Chimodzi mwazinthu zofunika kwambiri pa njirayi ndikugwiritsa ntchito ma flocculant—mankhwala omwe amalimbikitsa kusonkhana kwa tinthu tomwe timapachikidwa m'magulu akuluakulu, kapena ma floc, omwe amatha kuchotsedwa mosavuta m'madzi. Pakati pa mitundu yosiyanasiyana ya ma flocculant, ma flocculant a cationic ndi othandiza kwambiri chifukwa cha mphamvu yawo yabwino, yomwe imagwirizana kwambiri ndi tinthu tomwe timapachikidwa bwino tomwe timapezeka m'madzi otayidwa. Nkhaniyi ikufotokoza ma flocculant odziwika bwino omwe amagwiritsidwa ntchito posamalira madzi ndi momwe amagwiritsidwira ntchito.

Ma Polyacrylamides a Cationic(CPAM)

Ma Cationic Polyacrylamides, ndi ena mwa ma flocculant omwe amagwiritsidwa ntchito kwambiri mumakampani oyeretsera madzi. Kwa ogwiritsa ntchito ambiri, CPAM ndiye chisankho chawo chabwino. Ma polima awa amakhala ndi ma acrylamide subunits, omwe angapangidwe kuti aphatikizepo magulu ogwira ntchito a cationic. Kusinthasintha kwa ma Cationic polyacrylamides kuli mu kulemera kwawo kosinthika kwa mamolekyulu ndi kuchuluka kwa mphamvu, zomwe zimawalola kuti azisinthidwa kuti azigwiritsidwa ntchito mwanjira inayake. Ma C-PAM ndi othandiza kwambiri poyeretsera madzi otayira m'mafakitale ndi matope chifukwa cha mphamvu zawo zambiri zoyeretsera komanso kufunika kochepa kwa mlingo.

Poly(diallyldimethylammonium chloride) (PolyDADMAC)

PolyDADMAC ndi flocculant yogwiritsidwa ntchito kwambiri yodziwika bwino chifukwa cha kuchuluka kwa mphamvu komanso kugwira ntchito bwino pokonza madzi. Polima iyi ndi yothandiza kwambiri pokonza madzi ndi kutseka madzi, zomwe zimapangitsa kuti ikhale njira yotchuka yotsukira madzi akumwa, madzi otayira, ndi zinyalala zamafakitale. PolyDADMAC imagwira ntchito bwino limodzi ndi ma flocculant ena ndi ma coagulant, zomwe zimapangitsa kuti njira yonse yotsukira madzi ikhale yolimba popereka njira yolimba yosonkhanitsira ndi kuchotsa tinthu tating'onoting'ono.

Polyamines(PA)

Ma polyamines ndi gulu lina la ma flocculant a cationic omwe amagwiritsidwa ntchito kwambiri pochiza madzi. Ma composites awa, omwe akuphatikizapo poly (dimethylamine-co-epichlorohydrin) ndi mapangidwe ofanana, ali ndi mphamvu yamphamvu ya cationic charge, zomwe zimapangitsa kuti azigwira ntchito bwino kwambiri pochepetsa tinthu tating'onoting'ono tomwe tili ndi mphamvu yoipa. Ma polyamines ndi othandiza kwambiri pakuyeretsa madzi osaphika, kuchotsa zinthu zachilengedwe, komanso kuchiza zinyalala zosiyanasiyana zamafakitale. Kutha kwawo kupanga ma floc okhuthala kumapangitsa kuti nthawi yokhazikika ikhale yofulumira komanso kuti madzi okonzedwa azikhala omveka bwino.

Mapulogalamu ndi Ubwino

Ma flocculant a cationic amagwira ntchito yofunika kwambiri pa ntchito zosiyanasiyana zoyeretsera madzi, kuyambira pa madzi otayira m'matauni ndi kuyeretsa madzi akumwa mpaka kukonza zinyalala m'mafakitale. Ubwino wawo waukulu uli ndi kuthekera kwawo kothetsa bwino tinthu tomwe tili ndi mphamvu yoipa, zomwe zimapangitsa kuti floc ipangidwe mwachangu komanso moyenera. Izi zimapangitsa kuti madzi azimveka bwino, achepetse kutayikira, komanso kuti madzi azikhala abwino. Kuphatikiza apo, ma flocculant a cationic nthawi zambiri amagwiritsidwa ntchito limodzi ndi mankhwala ena oyeretsera, monga ma coagulant, kuti akwaniritse bwino njira yoyeretsera ndikukwaniritsa miyezo yabwino yamadzi.

Kugwiritsa ntchito ma flocculants a cationic ndikofunikira kwambiri pa njira zamakono zochizira madzi, zomwe zimapereka njira zogwira mtima komanso zodalirika zosonkhanitsira ndi kuchotsa tinthu tating'onoting'ono. Ma polyacrylamides, ma polyamines, ndi ma PolyDADMAC ndi ena mwa ma flocculants odziwika bwino komanso ogwira mtima omwe alipo masiku ano. Kugwiritsa ntchito kwawo mosiyanasiyana, kugwira ntchito bwino, komanso kusinthasintha kumapangitsa kuti akhale zida zofunika kwambiri pakuwonetsetsa kuti madzi oyera komanso otetezeka akupezeka.

Zachidziwikire, kusankha flocculant kumadaliranso momwe wogwiritsa ntchito amagwiritsira ntchito, kapangidwe ka zinthu, malo okhala, ndi zina zotero. Buku lotsogolera kugwiritsa ntchito mankhwala liyenera kutsatiridwa.
