PolyDADMAC: Ibintu by'ingenzi mu gukuraho amazi mu myanda

Kubura amazi mu myanda ni igice cy'ingenzi mu gikorwa cyo gutunganya imyanda. Intego yacyo ni ugukuramo amazi mu myanda neza, kugira ngo ingano y'imyanda ibe mike, kandi ikiguzi cyo kuyijugunya n'ubuso bw'ubutaka bigabanuke. Muri iki gikorwa, guhitamoFlocculantni ingenzi, na PolyDADMAC, nk'igikoresho cyizaIfurukuta ya Cationic Polymer, irimo kugira uruhare runini kurushaho.

Ubwa mbere, tugomba gusobanukirwa imiterere n'imiterere y'ibikomoka ku mwanda. Ibikomoka ku mwanda ahanini ni ibikomoka ku mwanda bikomeye bikorerwa mu gihe cyo gutunganya imyanda. Birimo ibintu bigoye nko imyanda y'ibinyabuzima, udukoko, uduce tudafite umwimerere na koloyide. Ibintu bikomeye bikomoka ku mwanda biba bifite ingufu nke kandi bikururana, mu gihe amazi yuzuza hagati y'ibikomoka ku mwanda, bityo ingano y'amazi y'ibikomoka ku mwanda ishobora kugera kuri 95%. Iyo ibikomoka ku mwanda idatunganyijwe ku gihe, bizatera umwanda w'ibidukikije. Kubwibyo, uburyo bwo gukura amazi mu mwanda neza byabaye ikibazo cy'ingenzi mu rwego rwo gutunganya imyanda.

Mu gikorwa cyo gukuraho amazi mu myanda,Imiti yo gukuraho amazi mu mazini ikintu cy'ingenzi kigira ingaruka. Iki gikoresho giteranya uduce duto two mu gitaka mu duce tunini binyuze mu gukurura amashanyarazi, gushyiramo amazi mu kirere, nibindi, byihutisha inzira yo kuzura no gukura amazi mu kirere. Nk'umuti ukoreshwa cyane mu gutunganya amazi yanduye no gukura amazi mu kirere, PolyDADMAC ikora neza mu gukura amazi mu kirere bitewe n'imiterere yayo yihariye ya molekile n'ubucucike bwayo bwa charge.

Imiterere ya molekile ya PolyDADMAC iha ubucucike bwinshi bw'amashanyarazi n'ubushobozi bwiza bwo kuyikuramo. Mu gihe cyo kuyikuramo amazi mu mazi, PolyDADMAC ishobora kwikurura vuba hejuru y'uduce tw'imyanda, ikagabanya imbaraga zitera hagati y'uduce binyuze mu gufunga amashanyarazi, kandi igatuma habaho uduce duto hagati y'uduce. Muri icyo gihe, imiyoboro ya molekile ya PolyDADMAC ishobora kandi gukora imiterere myiza y'urusobe rw'amazi, igafata uduce twinshi tw'imyanda hamwe, ikavana amazi hagati y'uduce tw'imyanda, kandi igakora uduce tworoshye gukurura amazi, ku buryo ingano y'amazi ishobora kugabanuka ikagera kuri 60-80% cyangwa ndetse no hasi, kandi ingano ikagabanukaho 75-87%.

Ugereranyije n'udukoko dusanzwe tw’ibimera bidafite umwimerere, PolyDADMAC ifite uburemere bwinshi bwa molekile n'ubucucike bw'amashanyarazi, ibi bikaba biyiha ubushobozi bwo gukurura cyane. Byongeye kandi,PolyDADMACifite ubushobozi bwo gushonga neza, yoroshye kuyikoresha, kandi ntitera umwanda wa kabiri. PD ubwayo ntabwo ikora sedimentation nk'iya alum, bityo ingano y'indi myanda ishobora kugabanuka. Izi nyungu zituma PolyDADMAC igira amahirwe menshi yo gukoreshwa mu bijyanye no gukura amazi mu myanda.

Imiterere ya molekile ya PolyDADMAC iha ubucucike bwayo bwa charge bwinshi n'ubushobozi bwiza bwo kuyinjizamo. Amatsinda menshi ya cationic ku ruhererekane rwayo rwa molekile ashobora gukorana n'amatsinda ya anionic ku buso bw'uduce tw'umucanga kugira ngo habeho imigozi ya ionic ihamye, bigatuma habaho kuyinjizamo gukomeye. Uku kuyinjizamo ntibifasha gusa kugabanya kwiruka hagati y'uduce, ahubwo binafasha gukora flocs nini.

Uretse imiterere ya molekile n'imiterere ya charge ya PolyDADMAC, ubwinshi bwayo n'ingano yayo nabyo ni ibintu by'ingenzi bigira ingaruka ku ngaruka zo kubura amazi mu mazi. Mu rugero runaka, uko ubwinshi bwa PolyDADMAC bwiyongera cyangwa ingano yiyongera, imikorere yo gukura amazi mu mazi ishobora kunozwa. Ariko, ubwinshi cyangwa ingano nyinshi bishobora gutera ingaruka zitandukanye, bigatuma habaho uburinzi bwa colloid, ibyo bigatuma ingaruka zo kubura amazi zigabanuka. Kubwibyo, mu bikorwa bifatika, igeragezwa n'uburyo bwo kunoza bigomba gukorwa hakurikijwe uburyo bwihariye bwo gutunganya imyanda n'imiterere y'imyanda kugira ngo hamenyekane ubwinshi n'ingano ya PolyDADMAC.
