Ukuhlanza amanzi angcolile kuwuhlelo olubalulekile lokuqinisekisa amanzi ahlanzekile naphephile ukuze asetshenziswe abantu kanye nokuvikela imvelo.Izindlela zendabuko zokwelashwa kwamanzi angcolile zithembele ekusetshenzisweni kweama-coagulants amakhemikhali, njenge-aluminium nosawoti wensimbi, ukuze kukhishwe ukungcola emanzini.Nokho, leziamakhemikhali okwelapha amanzi ezimboniniayabiza, adla amandla kagesi, futhi angaba nomthelela omubi kwezemvelo.
Ngenhlanhla, kuye kwavela isisombululo esisha emkhakheni wokuhlanza indle -ama-polyamines(PA).I-Polyamines iyiqembu lezinto eziphilayo ezitholakala ngokwemvelo kumangqamuzana aphilayo futhi anezakhiwo eziyingqayizivele eziwenza aphumelele kakhulu ekuhlanzeni amanzi angcolile.Ukusetshenziswa kwama-polyamine kuguqula umkhakha wokuhlanza amanzi angcolile futhi kunikeza isixazululo esimeme nesisebenza kahle ezinseleleni zokungcoliswa kwamanzi kanye nokushoda.
I-China ingelinye labathengi abakhulu bamakhemikhali okuhlanza amanzi emhlabeni, elinesidingo esikhula ngokushesha sezixazululo ezisebenzayo nezingabizi kakhulu zokuhlanza amanzi angcolile.Ukusetshenziswa kwama-polyamine embonini yokuhlanza amanzi angcolile yaseShayina kuya ngokuya kuba namandla ngenxa yokusebenza kwawo okuphezulu kanye nokusebenza kahle kwezindleko uma kuqhathaniswa namakhemikhali endabuko.
I-Polyamines inezinzuzo eziningana ngaphezu kwamakhemikhali okwelapha amanzi embonini evamile.Enye yezinzuzo eziyinhloko ukuhlobana kwawo okuphezulu nezinto ezingcolile ezihlukahlukene ezitholakala emanzini angcolile, njengezinsimbi ezisindayo, odayi, nezinhlanganisela eziphilayo.Ama-polyamine angakwazi ukujiya futhi antantise lezi zinto ezingcolisayo, okuholela ekukhishweni kwazo kalula emanzini.Le nqubo ithuthukisa kakhulu ukusebenza kahle okuphelele kwenqubo yokuhlanza amanzi angcolile, okuholela ekungcoleni kwekhwalithi engcono.
Enye inzuzo yama-polyamines isidingo sawo somthamo ophansi.Ama-polyamine angafinyelela izinga elifanayo lokususwa kokungcola njengamakhemikhali endabuko ngamanani amancane, okuholela ekongeni kwezindleko ezibalulekile zezitshalo zokuhlanza amanzi angcolile.Ngaphezu kwalokho, ukusetshenziswa kwe-polyamines kunganciphisa inani le-sludge elikhiqizwa phakathi nenqubo yokwelashwa, okungase kunciphise izindleko zokusebenza.
Ekugcineni, ukusetshenziswa kwePA ekuhlanzeni amanzi angcolile kuguqula umkhakha wokuhlanza indle futhi kunikeze isisombululo esimeme nesisebenza ngempumelelo ezinseleleni zokungcoliswa kwamanzi kanye nokushoda.Ngesidingo esikhulayo sezixazululo ezisebenzayo nezithengekayo zokwelashwa kwamanzi angcolile e-China, ukusetshenziswa kwama-polyamines embonini yokuhlanza amanzi angcolile kulindeleke ukuthi kukhule eminyakeni ezayo, kuhlinzekele indawo ehlanzekile nephephile kubo bonke.
