Ama-polyamineDlala indima ebalulekile ekubambeni kanye nokuguquguquka, izinyathelo ezimbili ezibalulekile ohambweni lokwelashwa kwamanzi. Ukuhlangana kufaka phakathi ukufika kwezinhlayiya emanzini ngokungezwa kwamakhemikhali. Ama-polyamines adlula kule nqubo ngokungathathi hlangothi amacala ezincemeni ezisusiwe, zibavumela ukuba zihlangane futhi zisebenzise ama-flocs. Lokhu kuyazuzisa ikakhulukazi ekwelapheni amanzi nge-turbidity ephezulu, njengoba ama-polyamine athuthukisa ukusebenza kahle kokususwa kwezinhlayiya.
Ngaphezu kwalokho, ama-polyamine anikela ngokubaluleka kokufukula, lapho izinhlayiya ezakhiwe zihlangana khona ukuze zakhe amabutho amakhulu. Ama-Flocs aphumela ahlukaniswe kalula namanzi asongeni noma e-filtration, eshiya ngemuva kwamanzi acacile nawahlanzekile. Ukusebenza kahle kwe-polyamines ekuthuthukiseni i-floccation esheshayo futhi eqinile kuyababeka eceleni njengesidlali esibalulekile kumasu wesimanje ukwelashwa kwamanzi.
Olunye uhlelo lokusebenza oluphawulekayo lwama-polyamines lusemandleni abo okusiza ekususweni kokungcola okufana nezinsimbi ezisindayo kanye nokungcoliswa kwezinto eziphilayo. Ngokwakha izakhiwo ngalezi zingcoliso, ama-polyamine enza lula ukuhanjiswa kwawo, asizile ngokwahlukana kwawo kwi-matrix yamanzi. Lokhu kuzuzisa ikakhulukazi ekubhekaneni nemithombo yamanzi engcoliswe yi-Industrial Disckarcher noma Runoff yezolimo.
Umthelela wezemvelo wama-polyamines ekwelashweni kwamanzi nawo awuphawuleka. Uma kuqhathaniswa nabakhokhi bendabuko, ama-polyamines avame ukudinga imithamo ephansi, okuholele ekunciphiseni ukukhiqizwa kwamakhemikhali. Lokhu akugcini nje ngokuhambisa inqubo yokwelashwa kepha kuqondanise nokuphambukiswa komhlaba wonke kwezindlela zokulawulwa kwamanzi ezizinzile nezinobungani.
Izitshalo zokwelashwa kwamanzi emhlabeni wonke ziye zamukela ngokwengeziwe ama-polyamines njengengxenye yohlobo lwezokwelapha ngenxa yokusebenza kwazo nokusebenza kahle. Abaphenyi nonjiniyela baqhubeka nokuhlola izindlela zokwandisa ukusetshenziswa kwama-polyamines, ukuqinisekisa ukusetshenziswa kwabo ngezimo ezahlukahlukene zokwelashwa kwamanzi.
Ekuphetheni, i-PA iguqula ukwelashwa kwamanzi ngokuhlinzeka ngesisombululo esisebenzayo nesimeme ukuqinisekisa ukutholakala kwamanzi ahlanzekile nephephile. Njengemiphakathi nezimboni zibhekene nezinselelo zokuntuleka kwamanzi nokungcola, indima yama-polyamine ekwandiseni izinqubo zokwelashwa kwamanzi iba yinto ebaluleke kakhulu. Ukutholwa kwama-polyamines kumelela igxathu elibalulekile ekufezeni ikusasa lapho ukufinyelela kwamanzi ahlanzekile kuyinto engokoqobo kubo bonke.
