In gutunganya amazi yanduye mu nganda, gukuraho ibintu bikomeye bimanitse ni ikintu cy'ingenzi. Ibi ntibifasha gusa kunoza ubwiza bw'amazi, ahubwo binagabanya kwangirika kw'ibikoresho no kuziba. Muri iki gihe, uburyo bwo gukuraho ibintu bikomeye bimanitse burimo cyane cyane sedimentation, filtration, flotation na flocculation. Muri byo, uburyo bwo gukurura ibintu bukoreshwa cyane kubera imikorere yabwo myiza kandi buhendutse. Muri ubu buryo, polymer yitwa PolyDADMAC igira uruhare runini.
PolyDADMAC, izina ryayo ryuzuye ni Poly diallyl dimethyl ammonium chloride, ni polymeri ifite molekile nyinshi. Ikorwa ahanini no gupomera diallyldimethylammonium chloride monomer binyuze muri polymerize y’umunyu. Ubu buryo bwo gupomera bukunze gukorwa hifashishijwe aside cyangwa umunyu, kandi polymeri ifite imiterere igororotse ishobora kuboneka. Akenshi iba ari amazi y’umuhondo cyangwa ifu y’umweru cyangwa utubumbe tw’umuhondo. Ifite ubushobozi bwo gushonga neza kandi ishobora gukwirakwizwa mu buryo bungana mu bisubizo by’amazi.
PolyDADMACifite ubucucike bwinshi bw'amashanyarazi kandi ikunze gukora nka polymer ya cationic. Ibi bivuze ko ishobora kwinjiza ibintu bikomeye bihagaze bifite ingufu nke n'uduce twa colloidal mu mazi kugira ngo bikore flocs nini, bityo bigakuramo neza ibintu bikomeye bihagaze. PolyDADMAC ikunze gukoreshwa nk'umuti wo gukurura no gufunga kandi ikoreshwa cyane mu nzego zitandukanye zo gutunganya amazi, harimo no gutunganya amazi yanduye mu nganda no gutunganya imyanda yo mu mijyi. Ishobora gukora flocs nini kandi nini mu mazi yanduye kandi ikavanaho neza ibintu bikomeye bihagaze, iyoni zikomeye z'ibyuma n'imyanda ihumanya ikirere.
Mu gutunganya amazi yanduye aturuka mu nganda zikora imyanda n'impapuro, uburyo PolyDADMAC ikora bugaragarira cyane cyane mu ngingo zikurikira:
Guhagarika imikoreshereze y'amashanyarazi: Kubera ko PolyDADMAC ifite ubucucike bwinshi bw'amashanyarazi, ishobora kwinjirira vuba ku bintu bikomeye bihagaze bifite ingufu nke n'uduce twa colloidal, bigatuma bita agaciro binyuze mu guhagarika imikoreshereze y'amashanyarazi, hanyuma bigaterana bikarema uduce duto tw'uduce tunini.
Igikorwa cyo gukurura: Uko floc ikorwa, izakurura ibintu bikomeye bihagaze n'uduce twa colloidal mu mazi yanduye bijya muri floc, bigatuma habaho gutandukana kw'ibintu bikomeye n'amazi binyuze mu bikorwa bifatika.
Ingaruka zo gufata Net-Capture: Polymeri zifite molekile nyinshi zishobora gukora imiterere y’urusobe rw’amakuru, zigafata ibintu bikomeye bimanitse n’uduce twa colloidal muri zo nk’urushundura rwo kuroba, bityo zikabasha gutandukana neza.
Ugereranyije n'ubundi buryo bwo gutunganya amazi yanduye, gukoresha PolyDADMAC mu kuvura amazi yanduye yo mu bwoko bwa pulp na paper mill bifite ibyiza bikurikira:
Ubucucike bwinshi bw'amashanyarazi: Ubucucike bwinshi bwa PolyDADMAC butuma ishobora kwinjiza neza ibintu bikomeye bihagaze bifite ingufu nke n'uduce twa colloidal, bigatuma uburyo bwo kubikora burushaho kuba bwiza.
Guhuza neza n'ibindi: PolyDADMAC igira ingaruka nziza ku bwoko butandukanye bw'amazi yanduye y'imyanda n'impapuro kandi ntigira ingaruka ku ihindagurika ry'ubuziranenge bw'amazi.
Umusaruro mwinshi n'ikoreshwa rike: Gukoresha PolyDADMAC nk'ukoFlocculantna coagulant bishobora kugabanya cyane ingano y'imiti, mu gihe binongera imikorere myiza yo kuvura no kugabanya ikiguzi cyo gukora.
Ntibingiza ibidukikije: PolyDADMAC ni polymeri ya cationic. Floc ikorwa nyuma yo gukoreshwa ntiyoroshye kubora ikaba ibintu byangiza kandi ni nziza ku bidukikije.
Mu gusoza, PolyDADMAC, nk'umuntuPolima nini ya molekile, ifite ibyiza byo gukora neza cyane, gukoresha make, no kubungabunga ibidukikije, kandi igira uruhare runini mu gutunganya amazi yanduye aturuka mu nganda zikora imyanda n'impapuro. Muri iki gihe uburyo bwo kurengera ibidukikije bigoye kwirinda, PolyDADMAC ni ibicuruzwa bizwi cyane byujuje imiterere y'ibicuruzwa birengera ibidukikije.
