Abo banamava amaninzi ekugcinweni kococeko lwamanzi amdaka bayazi ukubapdadmacyi-flocculant enozinzo olungaphezulu kakhulu kolwee-agents eziqhelekileyo. Uninzi lwee-flocculant ezithengiswayo zibuthathaka kakhulu, zisengozini yokonakala lilanga, amaqondo obushushu aphantsi, kunye nee-asidi/ii-alkali, zihlangana lula kwaye zingasebenzi emva kwesiqingatha senyanga zigcinwe, kwaye ziyasilela ngokulula xa zifakwa emanzini amdaka antsonkothileyo. Nangona kunjalo, i-Polydimethyldiallyl ammonium chloride ibonakalisa ukunyamezela okuphezulu kakhulu. Ukusebenza kwayo akuchaphazeleki ngamaqondo obushushu aphezulu ehlotyeni okanye amaqondo obushushu abandayo ebusika, nto leyo eyenza ukuba ibe yi-arhente "ezinzileyo" eyaziwayo kunyango lwamanzi amdaka.
Olu zinzo lubalaseleyo luvela kwisakhiwo salo esikhethekileyo nesiqinileyo semolekyuli. I-molecule skeleton yale arhente ifana ne-hemp rope chain ebotshelelwe ngokuqinileyo, enesakhiwo esizinzileyo kwaye akukho manqaku abuthathaka. Ngokwahlukileyo koko, ii-flocculants eziqhelekileyo zenziwe ikakhulu zii-molecules ezincinci ezibuthathaka eziqhekeka ngokulula kwaye zibole kwiindawo ezinobushushu obuphezulu, i-asidi, okanye i-alkaline, zilahlekelwa ngokupheleleyo yimpembelelo yazo ye-flocculation. Ngokwahlukileyo koko, i-polydimethyldiallyl ammonium chloride ibonisa uzinzo oluphezulu kakhulu lwe-molecular chain emva kwe-polymerization. Nokuba iphantsi kokuvezwa ixesha elide kwiindawo ezinobushushu obuphezulu, isakhiwo sayo se-molecular sihlala singaguquki kwaye sisebenza. Esi sesona sizathu siphambili sokuba inokukhawulezisa ukungcola kwamanzi amdaka kwaye yenze ii-flocs ezixineneyo nokuba igcinwe emoyeni ovulekileyo kwaye ikwimeko yobushushu obuphezulu.
Amaqela asasazwe ngokulinganayo atshajiswe kakuhle kwi-molecular chain yawo asebenza njengomqobo wendalo wokukhusela, enika i-arhente ukuhambelana okugqwesileyo komgangatho wamanzi. Ii-flocculants eziqhelekileyo azinalo ukhuselo lomphezulu kwaye zigqunywa lula yioyile kunye nokungcola emanzini amdaka, zilahlekelwa ngumthamo wazo wokufunxa. Nangona kunjalo, amaqela atshajiswe kakuhle ale arhente awasebenzi nje kuphela njengeenjongo zokufunxa ukungcola okuncinci, imibala, kunye nokungcola kodwa ayayihlukanisa nokuphazamiseka kwangaphandle njengee-asidi, ii-alkalis, ezinye iikhemikhali, kunye neoyile, ekhusela isakhiwo se-molecule esiphambili ekonakaleni. Oku kuvumela ukuhambelana okuzinzileyo namanzi amdaka antsonkothileyo kwimizi-mveliso yokudaya, ukuprinta, kunye neekhemikhali, apho ukuguquguquka kwe-pH kubalulekile.
Ngokuphathelele ukugcinwa nokuthuthwa, iingenelo zayo zidlula kakhulu ezo zeearhente ezifanayo. Uninzi lwee-flocculants ezigutyiweyo zichaphazeleka kakhulu kukufunxwa nokuxinana komswakama; nokuba amanqanaba aphezulu okufuma ngexesha lokugcina aya kubangela ukuba zonakale, zingasebenzi, kwaye zinganyibiliki. I-Polydimethyl diallyl ammonium chloride (PDMC) ibonisa uzinzo olukhethekileyo kwiimeko zolwelo kunye nezomeleleyo, ayibonisi ziphumo zeekhemikhali ezingafunekiyo. Izityalo zonyango lwamanzi amdaka zinokuwagcina ngobuninzi ngaphandle kokufuna ukulawulwa kobushushu okanye ukufuma ngabom. Ingagcinwa kwiindawo zokugcina ubushushu obuqhelekileyo ixesha elide kwaye ingasetyenziswa ngokuqhelekileyo nasemva kokuba iqandisiwe kwaye inyibilike ngaphandle ebusika, ngaphandle kweengxaki zokonakala okanye ukusilela, okunciphisa kakhulu iindleko ze-flocculant.
Ngaphezu koko, imveliso yayo efakwe i-flocculant ibonisa uzinzo olubalaseleyo. Ii-flocculant eziqhelekileyo zivelisa ii-floc ezikhululekileyo nezibuthathaka eziqhekeka ngokulula ngokuhamba kwamanzi okuncinci, okukhokelela ekubuyeleni kokungcola emanzini nasekungalungiseki konyango. Ngokwahlukileyo koko, i-PDMC inamandla amakhulu okufunxa nokubopha, ibopha ngokuqinileyo ukungcola okuncinci kunye neoyile ukuze yenze ii-floc ezixineneyo nezixineneyo. Ezi floc zibonisa ukumelana okunamandla nokukhukuliseka kokuhamba kwamanzi, iipropati ezibalaseleyo zokuzinza, kwaye zivelisa amaqhekeza amancinci odaka anokucinezelwa ngokuthe ngqo aze abunjwe, afaneleke ngokupheleleyo kwiimeko ezinzima zonyango lwamanzi amdaka njengeendawo zeoyile. Ngenxa yokuzinza kwayo okubanzi, le arhente ibe yi-flocculant ekhethwayo ixesha elide kushishino lonyango lwamanzi amdaka.
