Ama-PolyamineIdlala indima ebalulekile ekujiyeni nasekujiyeni, izinyathelo ezimbili ezibalulekile ohambweni lokwelashwa kwamanzi. Ukujiyeni kuhilela ukuqiniswa kwezinhlayiya emanzini ngokufaka amakhemikhali. Ama-polyamine avelele kule nqubo ngokunciphisa izindleko zezinhlayiya ezilengisiwe, ezivumela ukuthi zihlangane futhi zakhe ama-floc amakhulu, okulula ukuwasusa. Lokhu kuzuzisa kakhulu ekwelapheni amanzi anomswakama ophezulu, njengoba ama-polyamine ethuthukisa ukusebenza kahle kokususwa kwezinhlayiya.
Ngaphezu kwalokho, ama-polyamine anegalelo elikhulu ekuqhumeni, lapho izinhlayiya ezakhiwe zihlangana khona ukuze zakhe izinqwaba ezinkulu. Ama-floc aphumayo angahlukaniswa kalula emanzini ngokusebenzisa ukuthungwa noma ukuhlunga, kushiye amanzi ahlanzekile futhi acwebile. Ukusebenza kahle kwama-polyamine ekukhuthazeni ukuqhumeni okusheshayo nokuqinile kuwenza ahluke njengomdlali obalulekile emasu okwelapha amanzi esimanje.
Okunye ukusetshenziswa okuphawulekayo kwama-polyamine kusekukwazini kwawo ukusiza ekususweni kwezinto ezingcolisayo njengezinsimbi ezisindayo kanye nokungcola okungokwemvelo. Ngokwakha ama-complex ngala ma-contaminant, ama-polyamine enza kube lula ukuna kwawo, okusiza ekuhlukaniseni kwawo ne-matrix yamanzi. Lokhu kunenzuzo ikakhulukazi ekubhekaneni nemithombo yamanzi engcoliswe ukungcola kwezimboni noma ukugeleza kwamanzi kwezolimo.
Umthelela we-polyamines emvelweni ekuphathweni kwamanzi nawo uyaphawuleka. Uma kuqhathaniswa nama-coagulant endabuko, ama-polyamines avame ukudinga imithamo ephansi, okuholela ekunciphiseni ukukhiqizwa kodaka lwamakhemikhali. Lokhu akugcini nje ngokwenza inqubo yokwelapha ibe lula kodwa futhi kuhambisana nokusunduza komhlaba wonke kwemikhuba yokuphathwa kwamanzi esimeme futhi enobungani nemvelo.
Izitshalo zokwelapha amanzi emhlabeni wonke ziya ngokuya zamukela ama-polyamine njengengxenye yendlela yazo yokwelapha ngenxa yokuguquguquka nokusebenza kahle kwazo. Abacwaningi nonjiniyela bahlala behlola izindlela zokwenza ngcono ukusetshenziswa kwama-polyamine, beqinisekisa ukusetshenziswa kwawo ezimweni ezahlukahlukene zokwelashwa kwamanzi.
Ekuphetheni, ama-PA aguqula ukwelashwa kwamanzi ngokunikeza ikhambi eliphumelelayo neliqhubekayo ukuqinisekisa ukutholakala kwamanzi ahlanzekile naphephile. Njengoba imiphakathi nezimboni zibhekene nezinselele zokuntuleka kwamanzi nokungcola, indima yama-polyamine ekuthuthukiseni izinqubo zokwelashwa kwamanzi iba yinto ebaluleke kakhulu. Ukwamukelwa kwama-polyamine kumelela isinyathelo esibalulekile ekufinyeleleni ikusasa lapho ukufinyelela amanzi ahlanzekile kungokoqobo kubo bonke.
