Uburyo bwo guhitamo flocculant ikubereye mu gutunganya amazi yanduye

Mu gikorwa cyo gutunganya amazi yanduye, agomba kunyura mu byiciro bitandukanye by'imikorere, kandi nyuma yo gupimwa kugira ngo yuzuze ibisabwa, arasohoka. Muri uru rukurikirane rw'ibikorwa, flocculant igira uruhare runini.Flocculantishobora gukurura ibintu bito bito biri mu mazi. Gutuza, bigatuma byoroha kuyungurura. Ubwoko bw'ibintu bikurura amazi nabwo burakungahaye cyane. Uburyo bwo guhitamo ibintu bikurura amazi bikubereye nabwo ni ingenzi kandi ni ingenzi. Ku bijyanye no guhitamo ibintu bikurura amazi, abakora PAM na PAC bafite inama zikurikira:

Uburyo bwo guhitamo flocculant mu gutunganya amazi yanduye bugomba gutoranywa hakurikijwe imiterere y'amazi yanduye mu nganda runaka. Muri icyo gihe, biterwa kandi n'aho flocculant yongerwamo n'icyo ikoreshwa. Muri rusange, mu guhitamo flocculant idakomoka ku bimera, hagomba kwitabwaho imiterere y'amazi yanduye, hanyuma ugahitamo ikwiriye (umunyu w'icyuma, umunyu wa aluminiyumu cyangwa umunyu w'icyuma-aluminium, umunyu wa silikoni-aluminium, umunyu wa silikoni-ferric, nibindi); flocculant idakomoka ku bimera zirimo:polyaluminiyamu kloride (PAC), sulfate ya polyaluminiyumu (PAS), polyaluminum sulfochloride (PACSnasulfate ya polyferrike (PFS), n'ibindi. Muri byo, PAC na PAS zigaragara cyane zifite imiterere yo kwihuza neza n'impinduka mu bwiza bw'amazi yavuwe n'imiti isukura amazi, ingaruka nziza zo gufunga no kuyasukura, hamwe n'igiciro gito cy'imiti.

Mu gihe uhitamo ifu y’ibimera (flocculant) (nk'iyi:Polyacrylamide PAM), ahanini biterwa niba hakoreshwa polyacrylamide ya anionic, polyacrylamide ya cationic cyangwa polyacrylamide itari ionic. Polyacrylamide ya anionic ishingiye ku rugero rwa hydrolysis. Guhitamo cations muri rusange bikoreshwa mu gukuraho amazi mu myanda. Guhitamo polyacrylamide ya cationic ni ingenzi cyane. Inganda zitunganya imyanda zo mu mijyi muri rusange zikoresha polyacrylamide ya cationic ifite imbaraga ziciriritse. Cations nke muri rusange zikoreshwa mu gukuraho amazi mu mpapuro no mu gucapa no gusiga amarangi, kandi amazi yanduye yo mu miti muri rusange akoreshwa. Hitamo cations zikomeye n'ibindi. Buri bwoko bw'amazi yanduye bufite imiterere yabwo. Polyacrylamide itari ionic ikoreshwa cyane cyane mu bihe by'aside nke, naho PAM itari ionic ikoreshwa cyane mu nganda zicapa no gusiga amarangi.

Abatanga ibikoresho byo gutunganya amazitanga igitekerezo cy'uko guhitamo ibi bikoresho byose bigomba kugenwa hakurikijwe ikizamini. Mu ikizamini, menya ingano y'ingano iteganijwe, reba umuvuduko w'ingufu n'umuvuduko w'ingufu, ubare ikiguzi cyo kuvura, hanyuma uhitemo umuti uhendutse kandi ukwiriye wo gukurura.
