I-PDMDAAC (i-Polydimethyl diallyl ammonium chloride)

I-Polydimethyl diallyl ammonium chloride (PDMDAAC) iyi-ejenti yokwelapha amanzi engabizi kakhulu, esebenza ngezindlela eziningi engathatha indawo yama-ejenti amaningi endabuko ezimweni ezahlukahlukene, inikeza izinzuzo eziyinhloko ezifana nekhwalithi ethuthukisiwe, izindleko ezincishisiwe, kanye nokusebenza kahle okwandisiwe. Ingathatha indawo yama-ejenti okususa umbala angaphili njenge-polyferric sulfate kanye ne-polyaluminum chloride, kanye ne-activated carbon, ngomthamo we-1/3 kuphela wama-ejenti endabuko, okuholela emazingeni aphezulu okususa umbala kanye nokukhiqizwa kodaka okuncishisiwe ngesigamu. Ingaphatha kahle izinhlobo ezahlukene zamanzi amdaka aphindaphindayo, inciphise kakhulu izindleko zokulahla udaka.

Ngesikhathi esifanayo, ingathatha indawo ye-PAM ye-cationic evamile, inikeze amanani aphansi, ukuncibilika okungcono, kanye nokusebenza okulula nge-cationionicity efanayo. Ukusetshenziswa okuhlangene kunganciphisa izindleko ze-agent ngo-30%, futhi ingathatha indawo ngokuphelele yezimo zokususa amanzi ezivamile. Ngaphezu kwalokho, ingathatha indawo ye-aluminium salt coagulants njenge-alum ne-polyaluminum sulfate, engathinteki ukushisa kwamanzi, ikhiqiza ama-floc aminyene, ahlala ngokushesha, isuse izinkinga zezinsalela ze-aluminium, futhi izinzise ikhwalithi yokungcola.

Ingaphinde ihlanganiswe nempuphu yensimbi ukuze ithathe indawo ye-lime yokulungisa udaka, ngaphandle kokwandisa ivolumu yodaka, kungashiyi ukungcola, futhi kube lula ukwelashwa okungezansi. Nakuba udaka oluyinkimbinkimbi ludinga izinto ezihlanganisiwe, ukusebenza kahle kwezindleko kudlula kakhulu lokho kwezinto ezivamile. Esimweni samanje sokulawulwa kwezindleko okuqinile kanye nokuphishekela ukungcola okuzinzile, i-PDMDAAC, enezinzuzo zayo eziningi zomthamo ophansi, ukukhiqizwa kodaka okuphansi, imiphumela ezinzile, kanye nokulula kokusebenza, isibe yindlela yokuthuthukisa ekhethwayo yezitshalo ezinkulu zokuhlanza amanzi amdaka namanzi ukuze zithathe indawo yezinto ezivamile, zifinyelele kalula kokubili ikhwalithi yokwelapha amanzi ethuthukisiwe kanye nezindleko ezincishisiwe.
