Binyuze mu kongeramo polydimethyldiallylammonium chloride (PDMDAAC), polyaluminum chloride (PAC) na flocculant ivanze y’ibi byombi mu mikorere ihoraho ya membrane bioreactor (MBR), byakoreweho ubushakashatsi kugira ngo bigabanye MBR. Ingaruka zo kwangirika kw’urukiramende. Ikizamini gipima impinduka z’imikorere ya MBR, igihe cyo kwinjiza amazi mu miyoboro y’amazi (CST), Zeta potential, ingano y’urukiramende (SVI), ingano y’uduce tw’urukiramende n’ibice bya polymeri byo hanze y’umubiri n’ibindi bipimo, no kureba reactor Dukurikije impinduka z’urukiramende rukora mu gihe cyo gukora, hagaragajwe ibipimo bitatu by’inyongera n’uburyo bwiza bwo gukoresha ibipimo by’urukiramende bike.
Ibisubizo by'ibizamini bigaragaza ko flocculant ishobora kugabanya umwanda mu ruhu. Ubwo flocculant eshatu zitandukanye zongewe ku gipimo kimwe, PDMDAAC yagize ingaruka nziza mu kugabanya umwanda mu ruhu, hagakurikiraho flocculant, naho PAC igira ingaruka mbi cyane. Mu igeragezwa ry’inyongera ku gipimo n’igihe cyo gutanga ingero, PDMDAAC, flocculant ivanze, na PAC byose byagaragaje ko igipimo cy’inyongera cyari cyiza kuruta gutanga ingero mu kugabanya umwanda mu ruhu. Dukurikije impinduka zabaye mu muvuduko wa transmembrane (TMP) mu igerageza, bishobora kugaragara ko nyuma yo kongeramo bwa mbere 400 mg/L PDMDAAC, igipimo cyiza cy’inyongera ni 90 mg/L. Igipimo cyiza cy’inyongera cya 90 mg/L gishobora kongera igihe cy’imikorere ya MBR, kingana n’inshuro 3.4 z’ikirahure kidafite flocculant y’inyongera, mu gihe igipimo cyiza cy’inyongera cya PAC ari 120 mg/L. Ifuru ivanze igizwe na PDMDAAC na PAC ifite igipimo cy'uburemere cya 6:4 ntabwo ishobora gusa kugabanya umwanda wa membrane, ahubwo inagabanya ikiguzi cy'imikorere giterwa no gukoresha PDMDAAC gusa. Uhuje icyerekezo cyo gukura kwa TMP n'impinduka ku gaciro ka SVI, bishobora kugaragara ko igipimo cyiza cy'inyongera ya flocculant ivanze ari 60mg/L. Nyuma yo kongeramo flocculant, ishobora kugabanya agaciro ka CST k'uruvange rw'imyanda, yongera ubushobozi bwa Zeta bw'uruvange, igabanya agaciro ka SVI n'ingano ya EPS na SMP. Kongeramo flocculant bituma flocculant ikora neza cyane, kandi ubuso bwa module ya membrane. Urupapuro rw'akayunguruzo rwakozwe rurushaho kuba ruto, rukongera igihe cyo gukora cya MBR munsi y'amazi ahoraho. Flocculant nta ngaruka igaragara igira ku bwiza bw'amazi ya MBR. Reactor ya MBR ifite PDMDAAC ifite igipimo mpuzandengo cyo gukuraho cya 93.1% na 89.1% kuri COD na TN, uko bikurikirana. Igipimo cy'imyanda kiri munsi ya 45 na 5mg/L, kigera ku gipimo cya mbere cya A.
