Poly (diallyldimethylammonium chloride)—bizwi cyane nkaPDADMAC or PolyDADMAC—ni polymeri ya cationic ifite akamaro kanini ikoreshwa cyane mu gutunganya amazi mu nzego z'ibanze no mu nganda. Nk'umuti ugabanya ubukana bw'amazi, ugira uruhare runini mu gukuraho umwanda, gukuraho amazi mu mazi, gukuraho amabara, no gutandukanya amazi akomeye n'amazi.
Nubwo ikoreshwa mu buryo bwagutse, ahantu henshi ho gusukura amazi hakora amakosa ashobora kwirindwa mu guhitamo, gutanga no gukoresha PDADMAC. Ayo makosa ashobora gutuma imikorere y’amazi igabanuka, ubwinshi bw’imyanda iva mu mazi, imyanda ya shimi, ibyago byo kubahiriza amategeko, ndetse n’ikiguzi cy’imikorere kidakenewe.
Muri iyi nkuru, tuzasuzuma:
- Amakosa akunze kugaragara mu gukoresha PDADMAC
- Impamvu za tekiniki zituma habaho ibibazo mu mikorere

Guhuza neza bituma ubuvuzi bukomeza gukora neza.
PDADMAC mu ikoreshwa ry'inzego z'ibanze ugereranyije n'iry'inganda
Gusukura amazi yo kunywa mu Mujyi
Ibice by'ingenzi:
- Ubushyuhe buke
- Iyubahirizwa ry'amategeko agenga
- Ibisigaye bike
Amakosa akunze kuba arimo gukoresha imiti irenze urugero no kuyivanga nabi.
Gutunganya amazi yanduye mu nganda
Ibice by'ingenzi:
- COD iri hejuru
- Ibintu bikomeye biremereye
- Imiterere ihinduka
Amakosa akunze kuba arimo guhitamo nabi ibicuruzwa no kutagira igeragezwa ry’icyitegererezo.
Gukoresha inzoga nyinshi bishobora gutuma uduce dusubiranamo (ibicu byinshi), kongera ingano y'imyanda, no kongera ikiguzi cya shimi.
Yego, ariko imikorere ishobora kugabanuka, kandi gukosora igipimo akenshi biba ngombwa.
Yego. PDADMAC ikunze gukoreshwa hamwe na PAC kugira ngo irusheho gufungana.
Yego. Uburemere bwa molekile bigira ingaruka ku bushobozi bwo guhuza no gukomera kwa floc.
PDADMAC ni umuti ukomeye kandi ukoreshwa mu gutunganya amazi. Ariko, imikorere yayo ishingira cyane ku guhitamo neza, gukoresha neza ingano y'amazi, kuyavanga neza no kuyakurikirana.
Amakosa akunze kugaragara cyane—gutanga imiti idakwiye, kuvanga nabi, guhuza imiti idahuye, gupima nabi, no kubika nabi—bishobora kugabanya cyane imikorere myiza yo kuyivura no kongera ikiguzi cy’imikorere.
Mu gushyira mu bikorwa ibizamini byo muri laboratwari, igerageza ry’icyitegererezo, no gucunga imiti ishingiye ku makuru, inganda zitunganya amazi zishobora:
- Kunoza gukuraho umwanda
- Gabanya ingano y'ibishanga
- Igiciro cyo kuvura muri rusange kiri hasi
- Kongera ubushobozi bwo gushimangira imikorere ya sisitemu
Ku bahanga mu gutunganya amazi, kunoza ikoreshwa rya PDADMAC si uguhitamo polymer gusa—ni ugutegura ingamba zuzuye kandi zinoze zo gufunga.
Niba ushaka ubuyobozi bwa tekiniki cyangwa ibisubizo byiza bya PDADMAC byo gutunganya amazi mu mujyi cyangwa mu nganda, gukorana n'umutanga serivisi w'inararibonye utanga ubufasha muri laboratwari n'inama zihariye ni ingenzi kugira ngo imikorere yawe igende neza mu gihe kirekire.
