PolyDADMAC: Ibyingenzi byingenzi byo kuvoma amazi

Kuvoma umwanda nigice cyingenzi mubikorwa byo gutunganya imyanda. Intego yacyo ni ugukuraho neza amazi mumazi, kugirango umubare wibyondo ube muke, kandi amafaranga yo kujugunya hamwe nubutaka bwaragabanutse. Muri iyi nzira, guhitamo kwaFlocculantni urufunguzo, na PolyDADMAC, nkibikorwa byizaCationic Polymer flocculant, ifite uruhare runini.

Ubwa mbere, dukeneye gusobanukirwa ibigize nibiranga sludge. Umwanda ni imyanda ikomeye ikorwa mugihe cyo gutunganya imyanda. Irimo ibice bigoye nk'imyanda kama, amatsinda ya mikorobe, uduce duto duto na colloide. Ibikomeye byahagaritswe mumashanyarazi byishyuzwa nabi kandi bigasubiranamo, mugihe amazi yuzuza hagati yibisigara byahagaritswe, bityo amazi yambere yibigize umwanda ashobora kugera kuri 95% .Niba aya mase atavuwe mugihe, bizatera umwanda wa kabiri kubidukikije. Kubwibyo, uburyo bwo gukora neza kuvoma amazi byabaye ikibazo cyingenzi mubijyanye no gutunganya imyanda.

Muburyo bwo kuvomera amazi,Flocculants yo kumena amazini ikintu gikomeye kigira ingaruka. Flocculant ikusanya uduce duto duto mumashanyarazi mo ibice binini binyuze mumashanyarazi atabogamye, ikiraro cya adsorption, nibindi, byihutisha imyanda no kubura umwuma. Nkibicuruzwa bivura imiti bikoreshwa cyane mugutunganya amazi mabi no kubura umwanda, PolyDADMAC ikora neza muguhumeka neza kubera imiterere yihariye ya molekile hamwe nubucucike bwumuriro.

Imiterere ya molekulire ya PolyDADMAC itanga ubwinshi bwubwinshi bwubwiza hamwe na adsorption nziza. Mugihe cyo kubura umwanda, PolyDADMAC irashobora kwihuta kwihuta hejuru yubutaka bwigitaka, kugabanya imbaraga zanga hagati yibice binyuze mumashanyarazi, kandi bigateza imbere ibice binini hagati yibice. Muri icyo gihe, iminyururu ya molekuline ya PolyDADMAC irashobora kandi gukora imiterere y'urusobekerane rukora neza, igafata uduce twinshi twa shitingi hamwe, gusohora amazi hagati y’uduce duto duto, no gukora uduce tworoshye kubyuma, ku buryo amazi ashobora kugabanuka kugera kuri 60-80% cyangwa ndetse no munsi, kandi ijwi rishobora kugabanuka kuri 75-87%.

Ugereranije na flocculants gakondo, PolyDADMAC ifite uburemere buke bwa molekile hamwe nubucucike bwumuriro, bikabiha imbaraga zikomeye zo gukwirakwiza. Byongeye,PolyDADMACifite imikorere myiza yo gusesa, iroroshye kuyikoresha, kandi ntabwo itanga umwanda wa kabiri. PD ubwayo ntabwo itanga imyanda nka alum, bityo ingano yinyongera irashobora kugabanuka.Izo nyungu zituma PolyDADMAC ifite amahirwe menshi yo gukoreshwa mubijyanye no kuvomera amazi.

Imiterere ya molekulire ya PolyDADMAC itanga ubwinshi bwubwinshi bwubwiza hamwe na adsorption nziza. Amatsinda menshi atondekanya kumurongo wa molekuline arashobora kwitwara hamwe nitsinda rya anionic hejuru yibice bya silige kugirango bibe bihuza ionic bihamye, bikavamo adsorption ikomeye. Iyi adsorption ntabwo ifasha gusa kugabanya kwangwa hagati yuduce, ahubwo ifasha no gukora floc nini.

Usibye imiterere ya molekulari nuburyo bwo kwishyuza PolyDADMAC, kwibanda hamwe na dosiye nabyo ni ibintu byingenzi bigira ingaruka kumyunyu ngugu. Mu ntera runaka, uko kwibumbira hamwe kwa PolyDADMAC kwiyongera cyangwa ibipimo byiyongera, imikorere yamazi yo kumeneka irashobora kunozwa. Nyamara, hejuru cyane kwibandaho cyangwa ibipimo bishobora kuganisha ku ngaruka zinyuranye, bikavamo kurinda colloid, ari nako bigabanya ingaruka zo kubura umwuma. Kubwibyo, mubikorwa bifatika, kwipimisha no gutezimbere bigomba gukorwa hakurikijwe uburyo bwihariye bwo gutunganya imyanda hamwe nuburyo bwo kumena imyanda kugirango hamenyekane uburyo bwiza bwa PolyDADMAC hamwe na dosiye.
