PolyDADMAC, izina ryayo ryuzuye ni polydimethyldiallylammonium chloride, ni polymeri ishongesha amazi ya cationic ikoreshwa cyane mu bijyanye no gutunganya amazi. Bitewe n'ubucucike bwayo bwihariye bwa cationic charge hamwe n'ubushonge bwinshi bw'amazi, PolyDADMAC ni coagulant ikora neza ishobora gukuraho umwanda, ibara n'indi myanda mu mazi. Ariko, mu bikorwa bifatika, ikunze gukoreshwa nk'umutiumuti wo mu mazihamwe n'ibindi bikoresho bigabanya ubushyuhe mu gutunganya imyanda y'imyanda yo mu nganda.
Ibiranga n'uburyo bwo gukora kwa PolyDADMAC
PolyDADMAC yinjiza kandi igakusanya vuba uduce twa colloidal dufite ingufu nke hamwe n’ibintu bikomeye bihagaze mu mazi bitewe n’ubucucike bwayo bwinshi bwa cationic charge. Uburyo ikora bushingiye ahanini ku gukurura amashanyarazi, bigatuma utwo duce duto twivanga tukaba uduce duto, kugira ngo tubashe gukurwaho neza mu gihe cy’imvura cyangwa isukura.
Uburyo bwo guhuza imikorere ya PolyDADMAC
Guhuza ibice by'umubiri ni imwe mu ntambwe mu gikorwa cyo guhuza ibice by'umubiri. Bivuga inzira aho
"Indabo nto za alum" zakozwe mu gihe cyo gufungana zikora uduce duto dufite utuntu duto binyuze mu kuyungurura, gufunga amashanyarazi, guhuza no gufata imbunda.
Mu nganda zitunganya amazi, kunyuzamo amazi no kuyagabanya amashanyarazi bishyirwa mu byiciro bya "coagulation", mu gihe "bridging" na "net-capture" bishyirwa mu byiciro bya "flocculation". Ibinyabutabire bijyana na byo byitwa "coagulants" na "flocculants" uko bikurikirana.
Muri rusange abantu bemera ko PolyDADMAC ifite uburyo butatu bwo gukora: kunyuzamo umwuka, kugabanya amashanyarazi no guhuza imiterere y'umubiri. Ubundi bubiri bwa mbere ni bwo bw'ingenzi. Niyo mpamvu PolyDADMAC ishyirwa mu byiciro bya coagulants. Ariko, abantu benshi babona coagulants na flocculation nk'inzira imwe, bityo PolyDADMAC nayo yitwa flocculant.
Mu mikorere yo gutunganya amazi, PolyDADMAC ikoreshwa cyane cyane nk'umuyoboro wo gukurura amazi kugira ngo yongere ubuziranenge bw'amazi. By'umwihariko, itsinda ry'umunyu wa cationic quaternary ammonium rya PolyDADMAC rishobora gukora electrostatic aspirations hamwe na anionic suspensions cyangwa colloidal particles mu mazi, bigatuma haboneka uduce duto tw'uduce duto hanyuma tukadushyira mu mazi. Utwo duce duto turasuzumwa mu gihe cyo gusya cyangwa kuyungurura amazi kugira ngo habeho ubuziranenge bw'amazi.
Ibyiza bya PolyDADMAC
Ugereranyije n'imiti gakondo ikoreshwa mu gukaraba (alum, PAC, nibindi), PolyDADMAC ifite ibyiza bikurikira:
Ikora neza: PolyDADMAC ishobora gukuraho imyanda mu mazi vuba kandi ikanoza ubwiza bw'amazi.
Byoroshye gukoresha: Gukoresha kwayo biroroshye, shyiramo gusa mu bihe bikwiye.
Kuramba: PolyDADMAC ifite ubushobozi bwo kuguma neza kandi ntiyoroha nk'uko polyacrylamide ibikora.
Ingaruka zikomeye zo gukurura amazi: Itsinda ry'umunyu wa ammonium wa cationic quaternary riha PDMDAAC ubushobozi bwo gukurura amazi, bityo rigakora neza imiterere itandukanye y'amazi;
Ubudahangarwa bwiza bw'umunyu, aside na alkali: PDMDAAC ikwiriye imiterere y'amazi igoye, kandi iracyafite ubushobozi bwo gukurura amazi mu gihe cy'umunyu mwinshi, aside cyangwa alkali;
Igiciro gito: PolyDADMAC ifite ubushobozi bwo gukora flocculation nyinshi kandi ifite dose nke, ibyo bikaba bishobora kugabanya ikiguzi cyo gutunganya amazi.
Ubutaka buke: PolyDADMAC itanga ubutaka buke ugereranyije n’ibinyabutabire bidafite umwimerere n’ibinyabutabire bigabanya ikiguzi cyo gutunganya ubutaka.
Igipimo cya PolyDADMAC n'uburyo bwo kwirinda
Mu gihe ukoresha PolyDADMAC, inzira zo gukoresha zigomba gukurikizwa neza kugira ngo hamenyekane umusaruro mwiza wo kuvura no kwirinda ingaruka mbi zishobora kubaho. Ubusanzwe, nyuma yo kongeramo imiti igabanya ubushyuhe nka polyaluminium chloride, PolyDADMAC yongerwamo kugira ngo igere ku ngaruka nziza zo gufungana. Byongeye kandi, ingano igomba guhindurwa neza hakurikijwe ubwiza bw'amazi n'ibisabwa mu kuvura. Igipimo gikwiye gishobora kugenwa n'ibizamini by'ibinini.
Muri rusange,PolyDADMACIfite uruhare runini mu bijyanye no gutunganya amazi. Gusobanukirwa neza imiterere yayo n'ikoreshwa ryayo bizafasha gukoresha neza iki gicuruzwa mu kunoza ireme ry'amazi no kurengera ibidukikije.
