PolyDADMAC, izina ryayo ryuzuye ni polydimethyldiallylammonium chloride, ni polymer cationic water-soluble polymer ikoreshwa cyane mubijyanye no gutunganya amazi. Bitewe nubucucike bwihariye bwa cationic hamwe nubushyuhe bwamazi menshi, PolyDADMAC nigishobora gukora neza gishobora gukuraho neza imyanda, ibara nibindi byanduye mumazi. Ariko, mubikorwa bifatika, ikoreshwa kenshi nka aflocculantifatanije nandi ma coagulants yo gutunganya imyanda mvaruganda.
Ibiranga nuburyo bwibikorwa bya PolyDADMAC
PolyDADMAC yihuta cyane kandi igateranya uduce duto twa colloidal hamwe nubutaka bwahagaritswe mumazi kubera ubwinshi bwumuriro wa cationic. Uburyo bwibikorwa byabwo bushingiye cyane cyane ku gukurura electrostatike, itera utwo duce duto duhurira mu bice binini, ku buryo bishobora kuvanwaho neza mu gihe cy’imvura cyangwa iyungurura.
Uburyo bwa flocculation ya PolyDADMAC
Flocculation nimwe muntambwe mugikorwa cya coagulation. Yerekeza ku nzira aho i
"indabyo nto za alum" zakozwe mugihe cya coagulation zikora floc hamwe nuduce twinshi binyuze muri adsorption, kutabogama amashanyarazi, ikiraro no gufata net.
Mu nganda zitunganya amazi, adsorption hamwe no kutabogama kwamashanyarazi bishyirwa mubikorwa nka coagulation, mugihe ikiraro no gufata net byashyizwe mubikorwa nka flocculation. Imiti ijyanye nayo yitwa coagulants na flocculants.
Muri rusange abantu bemeza ko PolyDADMAC ifite uburyo butatu bwibikorwa: adsorption, kutabogama amashanyarazi hamwe nikiraro. Babiri ba mbere ningenzi. Niyo mpamvu PolyDADMAC ishyirwa mubikorwa nka coagulants. Nyamara, abantu benshi babona ko coagulation na flocculation ari inzira imwe, bityo PolyDADMAC nayo yitwa flocculant.
Mubikorwa byo gutunganya amazi, PolyDADMAC ikoreshwa cyane nka flocculant kugirango izamure ubwiza bwamazi. By'umwihariko, cateric quaternary ammonium groupe yumunyu wa PolyDADMAC irashobora kubyara electrostatike hamwe na anionic yahagaritswe cyangwa uduce duto twa colloidal mumazi, bikavamo kutabogama, bigakora uduce twinshi twinshi kandi tukabikemura. Izi floc zirasuzumwa mugihe gikurikiraho cyo gutembera cyangwa kuyungurura kugirango isukure ubwiza bwamazi.
Ibyiza bya PolyDADMAC
Ugereranije na flocculants gakondo (alum, PAC, nibindi), PolyDADMAC ifite ibyiza byingenzi bikurikira:
Bikora neza: PolyDADMAC irashobora gukuraho vuba umwanda mumazi no kuzamura ubwiza bwamazi.
Byoroshye gukora: Gukoresha biroroshye, gusa ongeraho mubihe bikwiye.
Kuramba: PolyDADMAC ifite ituze ryiza kandi ntisenyuka byoroshye nka polyacrylamide.
Ingaruka zikomeye za flokculasiyo: Itsinda ryumunyu wa catericary quaternary ammonium ritanga PDMDAAC imbaraga zikomeye zo guhindagurika, bityo bikavura neza imiterere itandukanye yamazi;
Kurwanya umunyu mwiza, aside na alkali birwanya: PDMDAAC ikwiranye nuburyo bwiza bwamazi meza, kandi iracyafite imikorere ihamye ya flocculation mugihe cyumunyu mwinshi, acide cyangwa alkaline;
Igiciro gito: PolyDADMAC ifite imikorere myiza ya flocculation hamwe na dosiye nkeya, ishobora kugabanya amafaranga yo gutunganya amazi.
Umuyoboro muke: PolyDADMAC itanga umwanda muke ugereranije na coagulants ya organic organique na flocculants kandi ikiza ibiciro nyuma yo gutunganya.
Igipimo cya PolyDADMAC no kwirinda
Mugihe ukoresheje PolyDADMAC, inzira zikorwa zigomba gukurikizwa kugirango harebwe ibisubizo byiza byo kuvura no kwirinda ingaruka zishobora kubaho. Mubisanzwe, nyuma yo kongeramo flocculants nka polyaluminium chloride, PolyDADMAC yongeweho kugirango igere ku ngaruka nziza ya coagulation. Byongeye kandi, dosiye igomba guhindurwa muburyo bukwiye ukurikije ubwiza bwamazi nibisabwa. Igipimo gikwiye gishobora kugenwa nibizamini bya jar.
Byose muri byose,PolyDADMACigira uruhare runini mu bijyanye no gutunganya amazi. Gusobanukirwa byimbitse kumiterere yabyo nibisabwa bizafasha gukoresha neza iki gicuruzwa kunoza ubwiza bwamazi no kurengera ibidukikije.
