Ama-Polyaminesidlala indima ebalulekile ekujimbeni nasekuhambeni, izinyathelo ezimbili ezibalulekile ohambweni lokuhlanza amanzi.I-coagulation ihilela ukuchithwa kwezinhlayiya emanzini ngokufaka amakhemikhali.Ama-Polyamine ahamba phambili kule nqubo ngokwenza izindleko zibe lula ezinhlayiyeni ezimisiwe, ezivumela ukuthi zihlangane futhi zakhe ama-flocs amakhulu, okulula ukuwasusa.Lokhu kunenzuzo ikakhulukazi ekwelapheni amanzi ane-turbidity ephezulu, njengoba ama-polyamine athuthukisa ukusebenza kahle kokukhipha izinhlayiyana.
Ngaphezu kwalokho, ama-polyamine anomthelela omkhulu ekugelezeni, lapho izinhlayiya ezibunjiwe zihlangana ukuze zenze uquqaba olukhulu.Ama-flocs avelayo angahlukaniswa kalula namanzi ngokusebenzisa i-sedimentation noma ukuhlunga, okushiya ngemuva amanzi ahlanzekile nahlanzekile.Ukusebenza kwe-Polyamines ekukhuthazeni ukugeleza okusheshayo nokuqinile kuwenza ahluke njengengxenye ebalulekile kumasu esimanje okwelapha amanzi.
Okunye ukusetshenziswa okuphawulekayo kwama-polyamine kusekwazini kwawo ukusiza ekukhipheni ukungcola okufana nezinsimbi ezisindayo nokungcola kwemvelo.Ngokwenza izinkimbinkimbi ngalokhu kungcola, ama-polyamine enza kube lula ukuna kwawo, asize ekuhlukaneni kwawo ne-matrix yamanzi.Lokhu kunenzuzo ikakhulukazi ekubhekaneni nemithombo yamanzi engcoliswe ukukhishwa kwezimboni noma ukugeleza kwezolimo.
Umthelela wemvelo wama-polyamines ekwelashweni kwamanzi nawo uyaphawuleka.Uma kuqhathaniswa nama-coagulant endabuko, ama-polyamine ngokuvamile adinga imithamo ephansi, okuholela ekunciphiseni kokukhiqizwa kodaka lwamakhemikhali.Lokhu akugcini nje ngokuqondisa inqubo yokwelapha kodwa futhi kuhambisana nomgomo womhlaba wonke wezinqubo zokuphatha amanzi ezisimeme futhi ezinobungani nemvelo.
Izitshalo zokuhlanza amanzi emhlabeni wonke ziya ngokuya zisebenzisa ama-polyamine njengengxenye yohlelo lwazo lokwelapha ngenxa yokuguquguquka nokusebenza kahle kwawo.Abacwaningi nonjiniyela baqhubeka behlola izindlela zokuthuthukisa ukusetshenziswa kwama-polyamines, baqinisekise ukuthi ayasebenza ezimeni ezahlukahlukene zokwelashwa kwamanzi.
Sengiphetha, i-PA yenza izinguquko ekuhlanzweni kwamanzi ngokunikeza isixazululo esiphumelelayo nesimeme ukuze kuqinisekiswe ukutholakala kwamanzi ahlanzekile naphephile.Njengoba imiphakathi nezimboni zibhekana nezinselelo zokushoda kwamanzi kanye nokungcoliswa, indima yama-polyamines ekuthuthukiseni izinqubo zokuhlanza amanzi iya ngokuya ibaluleke kakhulu.Ukwamukelwa kwama-polyamine kumele isinyathelo esibalulekile ekufinyeleleni ikusasa lapho ukufinyelela emanzini ahlanzekile kuyinto engokoqobo kubo bonke.
