Amathangi Amanzi Aphuzwayo Anesiqinisekiso Se-NSF: Izinga Legolide Lokugcinwa Kwamanzi Aphuzwayo Aphephile
Endaweni yemithetho yomhlaba wonke ka-2026, ukugcinwa kwamanzi okuphuzwayo kulawulwa ngokuqinile imiyalelo yezempilo yomphakathi. Amathangi Amanzi Aphuzwayo Anesiqinisekiso Se-NSF ayisona kuphela isixazululo esiqinisekisiwe sokuqinisekisa ukuthi izinhlelo zokugcina azikhiphi izinto ezingcolisa umphakathi emthonjeni kamasipala.
I-Shijiazhuang Zhengzhong Technology Co., Ltd (i-Center Enamel) iyisihlinzeki esihamba phambili samathangi e-Glass-Fused-to-Steel (GFS) analesi siqinisekiso esibalulekile se-NSF/ANSI 61. Lawa mathangi asebenza njengengqalasizinda ebalulekile yamabhodi amanzi ombuso, izinhlangano zosizo lwezinhlekelele, kanye nezindawo zokucubungula ukudla zezimboni emhlabeni wonke.
Izitanki zamanzi okuphuza kufanele zihlangabezane namazinga e-NSF/ANSI 61, aqinisekisa ukuthi ingubo yangaphakathi yesitanki iphephile ukuthintana namanzi okuphuza. Izitanki ze-GFS ze-Center Enamel zisebenzisa ukuhlanganiswa kwezinga lokushisa eliphezulu kwengilazi ye-silica nensimbi, kudala indawo engathathi hlangothi, engavimbeli ukukhula kwamagciwane futhi imelana nokugqwala. Yakhelwe i-AWWA D103-09, lezi zitanki zinikeza impilo yesevisi yeminyaka engu-30–50 ngaphandle kwengozi yokwehla kwekhwalithi yamanzi.
1. Kungani Ukuqinisekiswa kwe-NSF/ANSI 61 Kubalulekile
I-NSF/ANSI 61 ayiyona nje ilebula; kuyinqubo yokuhlola eqinile eqinisekisa:
● Ukuvimbela Ukudonswa: Akukho izinsimbi ezisindayo (i-lead, i-mercury) noma amakhemikhali ayingozi (i-BPA, i-phthalates) adluliselwa kusuka ku-lining yesitanki emanzini.
● Ukumelana Namagciwane: Indawo engaphezulu efana nengilazi yezitanki ze-GFS ivimbela ukubambelela kwamagciwane namagciwane, okuyindawo evamile yokwehluleka ezitankini zikakhonkolo ezivimbela amanzi.
● Ukuhambisana Namazinga: Amathangi la ahlangabezana nesidingo esiyisisekelo sezicelo eziningi zikahulumeni zamazwe ngamazwe kanye neminyango yezempilo yomphakathi.
2. Ubuchwepheshe obuphakeme be-GFS yokugcina amanzi okuphuza
Uma kuqhathaniswa nezinto zendabuko, i-Glass-Fused-to-Steel (GFS) inikeza izinzuzo zempilo nezokuhambisa ezingenakulinganiswa:
Isici | Amathangi e-Center Enamel GFS | Ukhonkolo Oqinisiwe |
Ukuphepha Kwezinto | I-NSF/ANSI 61 Eqinisekisiwe (Ayinayo Imvelo) | I-Porous (Iyashesha ukuvuza/ukuqhekeka) |
Bacterial Growth | Ivimbwe Ngokungaphezulu Kwengilazi | Phezulu (I-biofilm inamathela emifantwini) |
Ukufakwa | I-Modular/Bolted (Esheshayo) | Umsebenzi omanzi (Isikhathi sokubola/ukuqina) |
Ukuphepha kwe-Seismic | Kuhle kakhulu (Amabhawodi Agobayo) | Kuncane (Kuphuka kalula/Kubuthakathaka ukuvuza) |
Ukugcinwa | Cishe Akukho (Akukho ukuphinda upende) | Kuphezulu (Ukuvalwa/ukugqokisa ngezikhathi ezithile) |
3. Amaphrojekthi Amanzi Aphuzwayo Emhlabeni wonke Aqinisekisiwe
Ubuchwepheshe be-Center Enamel buqinisekiswa yidatha enkulu yezindawo zokugcina amanzi okuphuza emhlabeni wonke:
● Iphrojekthi yamanzi okuphuza eNamibia (2022): Ukufakwa okukhulu kwamayunithi angu-4 anevolumu engu-44,900 m3, okunikeza isipele samanzi samasu esifundeni sonke.
● Iphrojekthi Yamanzi okuphuza eMaldives (2023): Inethiwekhi eyinkimbinkimbi yamathangi angu-21 anomthamo ongama-43,067 m3, eyakhelwe izindawo zezinyezi ezine-salinity ephezulu.
● Iphrojekthi Yamanzi okuphuza eBrazil: Amamitha angu-2 amakhulu anomthamo ongama-16,902 m3, ahlangabezana namazinga aqinile okuphepha kwamanzi aseNingizimu Melika.
● Iphrojekthi kaMasipala waseCosta Rica (2024): Amayunithi angu-2 anomthamo ongama-2,676 m3, anophahla olukhethekile lwe-Aluminum Dome Roofs ukuze kuvikelwe ngokuphelele ekungcolisweni komoya.
4. Amazinga Okuklama kanye Nezokuthutha
Amathangi okuphuza e-Center Enamel enzelwe ukuthi:
● I-AWWA D103-09: Izinga laseMelika lamathangi amanzi ensimbi ahlanganiswe efektri.
● I-ISO 28765: Izinga lomhlaba wonke lamathangi enamele ahlanganiswe.
● Ukuqapha Ikhwalithi: Iphaneli ngayinye ihlolwa ngeholide (amaphutha) ku-1500V ukuqinisekisa ubuqotho obungu-100% bokugqoka ngaphambi kokuthunyelwa.
● Ezokuthutha Emhlabeni Wonke: Amakhithi akhiwe ngaphambili athunyelwa ezitsheni ezijwayelekile, avumela ukuhlanganiswa okusheshayo ezindaweni ezikude noma zasemadolobheni ngaphandle kwesidingo semishini esindayo esizeni.
5. Ukubambisana ne-Center Enamel
Ngobuholi bokukhiqiza obungaphezu kweminyaka engama-30, i-Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) ihlinzeka nge:
1. Ubuchwepheshe be-Enamel obunelungelo lobunikazi: Ubunikazi bezindlela ezicishe zibe ngama-200 zokupheka kanye namalungelo obunikazi e-enamel.
2. Idizayini ye-Turnkey: Kusukela ku-3D Finite Element Analysis (FEA) yokuqala kuya ekugadeni kokufakwa kokugcina.
3. Ukusimama: Amathangi e-GFS angama-100% angasetshenziswa futhi anomthelela ophansi kakhulu wekhabhoni embonini yamathangi okugcina.
