Iipolyaminesidlala indima ebalulekileyo ekudibaniseni kunye nokushukuma, amanyathelo amabini abalulekileyo kuhambo lokucocwa kwamanzi.I-Coagulation ibandakanya ukuchithwa kwamasuntswana emanzini ngokudityaniswa kweekhemikhali.Iipolyamines zigqwesa kule nkqubo ngokunciphisa iintlawulo kwiinqununu ezimisiweyo, ezivumela ukuba zihlangane kwaye zenze iiflocs ezinkulu, ezilula ukususa.Oku kunenzuzo ngakumbi ekuphatheni amanzi ane-turbidity ephezulu, njengoko iipolyamines ziphucula ukusebenza kakuhle kokususa amasuntswana.
Ngaphaya koko, iipolyamines zinegalelo elikhulu kwi-flocculation, apho amasuntswana abunjiweyo ahlanganayo ukuze enze iindimbane ezinkulu.Iiflokhi ezibangelwayo ziyakwazi ukuhlukana ngokulula emanzini ngokusebenzisa i-sedimentation okanye i-filtration, ishiya ngasemva amanzi acacileyo nacocekileyo.Ukusebenza kwePolyamines ekukhuthazeni ukushukuma okukhawulezileyo nokomelela kubenza bahluke njengomdlali ophambili kwizicwangciso zangoku zokucocwa kwamanzi.
Olunye usetyenziso oluphawulekayo lwe-polyamines luxhomekeke ekukwazini ukuncedisa ekususeni izinto ezingcolileyo ezifana nesinyithi esinzima kunye nezinto ezingcolileyo eziphilayo.Ngokwenza ii-complex kunye nezi zingcolisi, i-polyamines iququzelela imvula, inceda ukuhlukana kwabo kwi-matrix yamanzi.Oku kuluncedo ngakumbi ekujonganeni nemithombo yamanzi engcoliswe kukukhutshwa kwemizi-mveliso okanye ukuqhutywa kwezolimo.
Impembelelo yokusingqongileyo ye-polyamines kunyango lwamanzi nayo iyaphawuleka.Xa kuthelekiswa ne-coagulants yendabuko, iipolyamines zihlala zifuna iidosi ezisezantsi, ezikhokelela ekunciphiseni ukuveliswa kodaka lwekhemikhali.Oku akupheleli nje ekufezekiseni inkqubo yonyango kodwa kukwangqamanisa nokutyhalela phambili kwehlabathi kwiindlela zolawulo lwamanzi oluzinzileyo kunye ne-eco-friendly.
Iindawo zokucocwa kwamanzi kwihlabathi jikelele ziya zisanda kwamkela iipolyamines njengenxalenye yerejimeni yazo yonyango ngenxa yokuguquguquka kwazo kunye nokusebenza kakuhle.Abaphandi kunye neenjineli baqhubeka behlola iindlela zokwandisa ukusetyenziswa kweepolyamines, ukuqinisekisa ukusetyenziswa kwazo kwiimeko ezahlukeneyo zokunyanga amanzi.
Ukuqukumbela, i-PA iguqula unyango lwamanzi ngokubonelela ngesisombululo esisebenzayo nesizinzileyo sokuqinisekisa ukufumaneka kwamanzi acocekileyo nakhuselekileyo.Njengoko uluntu kunye nemizi mveliso izamana nemingeni yokunqongophala kwamanzi kunye nongcoliseko, indima yeepolyamines ekwandiseni iinkqubo zokucocwa kwamanzi iya ibaluleke kakhulu.Ukwamkelwa kweepolyamines kubonisa inyathelo elibalulekileyo ekuphumezeni ikamva apho ukufikelela kumanzi acocekileyo kuyinyani kubo bonke.
