Ni iki gikoresho gikoreshwa mu gutunganya ingano y'ibimera (Flocculation)?

Guteranya ibice by'amaziNi uburyo bukoreshwa mu nganda zitandukanye, cyane cyane mu gutunganya amazi no gutunganya amazi yanduye, kugira ngo hakusanyirizwe uduce duto n'udukoko two mu bwoko bwa colloid mu duce duto twa floc. Ibi byoroshya kubikuramo binyuze mu gusya cyangwa kuyungurura. Imiti ikoreshwa mu gusya izwi nka flocculants. Imwe mu miti ikoreshwa cyane kandi ikoreshwa cyane ni polyacrylamide.

Polyacrylamideni polymer yakozwe muri monomer za acrylamide. Ibaho mu buryo butandukanye, harimo anionic, cationic, na non-ionic, buri imwe ifite akamaro kayo. Guhitamo ubwoko bwa polyacrylamide biterwa n'imiterere y'uduce tw'amazi n'umusaruro wifuza wo gukora flocculation.

Polyacrylamide ya Anionic ifite amashanyarazi mabi kandi ikunze gukoreshwa mu kuvura amazi yanduye arimo uduce twangiritse nk'ibumba n'ibintu bikomoka ku bimera. Polyacrylamide ya Cationic, ku rundi ruhande, ifite amashanyarazi meza kandi ikora neza mu kuvura amazi ikoresheje uduce twangiritse nk'ibintu bikomeye bimanitse n'ibitaka. Polyacrylamide itari ionic nta bushobozi ifite kandi ikwiriye gukurura uduce twinshi tw'uduce.

Uduce duto twa polyacrylamide dukora mu kwikurura hejuru y’uduce duto, tugakora ibiraro hagati yatwo, kandi tugateranya uduce duto. Uduce duto twavuyemo tworoshye guhagarara cyangwa kuyungurura mu mazi. Polyacrylamide ikundwa cyane kubera uburemere bwayo bwinshi bwa molekile, ibyo bikaba byongera ubushobozi bwayo bwo guhuza no guhuza.

Uretse polyacrylamide, hari n'indi miti ikoreshwa mu gukurura, bitewe n'ibyo ikeneye mu buryo bwihariye bwo kuyivura. Imiti isanzwe, nkaSulfate ya aluminiyumu(alum) na ferric chloride, bikunze gukoreshwa mu gutunganya amazi. Iyi miti ikora ibyuma bya hydroxide flocs iyo byongewe mu mazi, bigafasha mu gukuraho uduce duto duto.

By’umwihariko, Alum imaze imyaka myinshi ikoreshwa cyane mu gutunganya amazi. Iyo yongewe mu mazi, alum irahita ikoreshwa mu gushonga, igakora aluminium hydroxide flocs ifata imyanda. Hanyuma flocs zishobora guturika, maze amazi asanzwe agatandukana n’umukungugu.

Gutunganya amazi mu mazi ni intambwe y'ingenzi mu gutunganya amazi, bituma imyanda ikurwaho kandi amazi meza agatunganywa. Guhitamo icyuma gitunganya amazi mu mazi biterwa n'ibintu nk'imiterere y'amazi agomba gusukurwa, ubwoko bw'uduce duhari, n'umusaruro wifuza wo kuyatunganya. Polyacrylamide n'ibindi bikoresho bitunganya amazi mu mazi bigira uruhare runini mu kongera imikorere myiza y'amazi n'amazi yanduye, bigira uruhare mu gutanga amazi meza kandi meza ku mpamvu zitandukanye.
