IiPolyaminesIdlala indima ebalulekileyo ekujikeni nasekujikeni kwamanzi, amanyathelo amabini abalulekileyo kuhambo lokunyanga amanzi. Ukujikanisa amanzi kubandakanya ukungasebenzi kakuhle kwamasuntswana emanzini ngokongeza iikhemikhali. Iipolyamines ziyabalasela kule nkqubo ngokunciphisa iindleko kumasuntswana axhonyiweyo, zivumela ukuba zihlangane kwaye zenze iiflocs ezinkulu, ezilula ukuzisusa. Oku kuluncedo ngakumbi ekunyangeni amanzi anokuxinana okuphezulu, njengoko iipolyamines zonyusa ukusebenza kakuhle kokususwa kwamasuntswana.
Ngaphezu koko, iipolyamines zinegalelo elikhulu ekufudumaleni, apho amasuntswana enziweyo ahlangana khona ukuze enze iimbumba ezinkulu. Iiflocs eziphumayo zinokwahlulwa lula emanzini ngokusebenzisa ukuthuthwa okanye ukuhluzwa, okushiya amanzi acocekileyo nacocekileyo. Ukusebenza kakuhle kweepolyamines ekukhuthazeni ukufudumaleni okukhawulezayo nokuqinileyo kubenza bahluke njengomdlali ophambili kwizicwangciso zanamhlanje zonyango lwamanzi.
Enye indlela ephawulekayo yokusebenzisa iipolyamines kukuba ziyakwazi ukunceda ekususeni izinto ezingcolisayo ezifana neentsimbi ezinzima kunye nezinto ezingcolisayo eziphilayo. Ngokwenza ii-complexes ngezi zinto zingcolisayo, iipolyamines zenza kube lula ukuna kwazo, zincede ekwahlukaniseni kwazo ne-matrix yamanzi. Oku kuluncedo ngakumbi ekulungiseni imithombo yamanzi engcoliswe zizinto ezikhutshwa yimizi-mveliso okanye amanzi aphuma emasimini.
Impembelelo ye-polyamines kwindalo esingqongileyo ekunyangweni kwamanzi nayo ibalulekile. Xa kuthelekiswa ne-coagulants zemveli, ii-polyamines zihlala zifuna iidosi eziphantsi, nto leyo ebangela ukwehla kwemveliso yodaka lweekhemikhali. Oku akupheleli nje ekwenzeni lula inkqubo yonyango kodwa kuhambelana nokunyanzeliswa kwehlabathi jikelele kweendlela zolawulo lwamanzi ezizinzileyo nezinobuhlobo nokusingqongileyo.
Izityalo zonyango lwamanzi kwihlabathi liphela ziyanda ukusebenzisa ii-polyamines njengenxalenye yenkqubo yazo yonyango ngenxa yokuguquguquka kwazo nokusebenza kwazo kakuhle. Abaphandi kunye neenjineli bahlala behlola iindlela zokuphucula ukusetyenziswa kwee-polyamines, beqinisekisa ukusetyenziswa kwazo kwiimeko ezahlukeneyo zonyango lwamanzi.
Ukuqukumbela, ii-PA ziguqula unyango lwamanzi ngokubonelela ngesisombululo esisebenzayo nesizinzileyo ukuqinisekisa ukufumaneka kwamanzi acocekileyo nakhuselekileyo. Njengoko uluntu kunye namashishini bejamelene nemingeni yokunqongophala kwamanzi kunye nongcoliseko, indima ye-polyamines ekuphuculeni iinkqubo zonyango lwamanzi iba yinto ebalulekileyo ngakumbi. Ukwamkelwa kwe-polyamines kubonisa inyathelo elibalulekileyo ekufezekiseni ikamva apho ukufikelela kumanzi acocekileyo kuyinyani kubo bonke.
