Ingabe Ithangi Lamanzi Lensimbi Egqwalisiwe Liphephile Ukuphuza Amanzi?
Lapho uhlela uhlelo lokuhlinzeka ngamanzi ezindlini, ezolimo, noma ezindaweni zasemakhaya, ukuqinisekisa ukuphepha kwamanzi agciniwe kubaluleke kakhulu. Phakathi kwezinketho ezahlukahlukene zokugcina amanzi, amathangi amanzi ensimbi egqwalisiwe asetshenziswa kabanzi ngenxa yokuqina kwawo okukhethekile nokungabizi kwawo. Nokho, umbuzo obalulekile usekhona kubanikazi bezakhiwo nonjiniyela bamaphrojekthi: Ingabe amathangi amanzi ensimbi egqwalisiwe aphephile ukuphuza amanzi?
Impendulo emfushane ithi yebo, inqobo nje uma zenziwe ngokwezindinganiso zanamuhla, zigcinwa kahle, futhi zifakwe ulwelwesi lwangaphakathi olugunyaziwe lokudla. Nokho, amathangi amadala angenalwelwesi noma amasistimu angagcinwa kahle angabangela izingozi zekhwalithi yamanzi nezempilo.
1. Ukuqonda Inqubo Ye-Galvanization kanye Nokukhishwa Kwe-Zinc
Amathangi ensimbi e-galvanized ambozwe ngongqimba oluvikelayo lwe-zinc ngokusebenzisa inqubo ye-hot-dip galvanizing ukuvimbela ukugqwala nokugqwala komoya. Nakuba i-zinc iyinto ebalulekile emzimbeni womuntu, ukudla kwayo ngokweqile kungabangela imiphumela emibi empilweni.
● Indlela Yokukhishwa: Lapho amanzi ehleli ngaphakathi kwethangi elisha le-galvanized, inani elincane le-zinc lingancibilika emanzini (ukukhishwa).
● Umthelela Wamakhemikhali Wamanzi: Izinga lokukhishwa kwe-zinc lithonywa kakhulu yi-pH yamanzi. Amanzi ane-asidi (i-pH ephansi) asheshisa ukucekelwa phansi kongqimba lwe-zinc, okuholela ekugxileni okuphezulu kwensimbi encibilikile, ukunambitheka okungemnandi kwensimbi, nokungacaci kahle kwamanzi.
● Umongo Womlando vs. Izindinganiso Zanamuhla: Ingqalasizinda endala ye-galvanized noma amathangi amadala asezingeni eliphansi kwesinye isikhathi ayenomkhondo womthofu phakathi kwezingqimba ze-zinc alloy, okubeka izingozi ezinkulu zezempilo, ikakhulukazi ezinganeni. Ukukhiqizwa kwanamuhla kulawula ngokuqinile ubumsulwa ukuze kuqedwe ukungcola kwezinsimbi ezisindayo.
2. Iqhaza Elibalulekile Lezinto Zangaphakathi Ezisezingeni Lokudla
Ukuze kuqinisekiswe ukuthi ithangi lamanzi lensimbi ye-galvanized liphephile 100% ekugcineni amanzi okuphuza isikhathi eside, izindinganiso zobunjiniyela zanamuhla zithembela ekuvikelweni kwangaphakathi okuyisithiyo:
● Ama-Liner e-Geomembrane: Amathangi amaningi e-galvanized modular asebenzisa ama-liner angaphakathi enziwe ngokwezifiso, ezinga lokudla (njenge-high-density polyethylene [HDPE] noma i-EPDM rubber). Lawa ma-liner ahlukanisa ngokuphelele amanzi okuphuza agciniwe odongeni lwensimbi ye-galvanized.
● Izinto Zokumboza nge-Epoxy: Izinto zokumboza nge-epoxy eziqinisekisiwe zokudla noma i-polymer spray ziyasetshenziswa ukuvala ingaphakathi.
● Ukuqeda Ukuchithwa Kwezinto: Ngokufaka ulwelwesi lwangaphakathi olugunyaziwe, amanzi awaze athintana ngqo nongqimba lwe-zinc noma insimbi, ngaleyo ndlela kuvinjelwa ngokuphelele ukuchithwa kwezinsimbi, kuqedwe izinkinga zokunambitheka kwamanzi, futhi kuhlangabezane namakhodi ezempilo omphakathi aqinile afana ne-NSF/ANSI 61.
3. Uhlu Lokuphepha Lwamathangi E-Galvanized Okuphuza
Ngaphambi kokusebenzisa ithangi lamanzi lensimbi ye-galvanized ukuze abantu balidle, abaphathi bezikhungo nabanikazi bezindlu kufanele baqinisekise lokhu okulandelayo:
● Izitifiketi Zokuthobela: Qinisekisa ukuthi ithangi noma ulwelwesi lwangaphakathi luhlangabezana nezindinganiso ezaziwayo zamanzi okuphuza (ezifana ne-NSF/ANSI 61, AWWA D103, noma AS/NZS 4020).
● Ukuqinisekiswa kwe-Lining: Qinisekisa ukuthi ithangi linomgqomo we-polyethylene wezinga lokudla noma i-epoxy coating eklanyelwe amanzi okuphuza.
● Ukuhlolwa Kwekhwalithi Yamanzi: Hlola njalo izinkomba zamanzi, okuhlanganisa amazinga e-pH nokungafihleki, ukuze uqinisekise ukuthi uhlelo lokugcina luhlala luzinzile futhi alugqwali.

Imibuzo Ejwayelekile (FAQ)
Q: Can you drink water directly from an unlined galvanized steel tank?
A: Nakuba ukuphuza amanzi esikhathini esifushane ethangi elisanda kufakwa i-zinc ngokuvamile kungabangeli ubuthi obunamandla, amathangi angena-lining ngokuvamile ayakhuthazwa ukuthi angasetshenziswa njengamanzi okuphuza asekhaya isikhathi eside. Ngokuhamba kwesikhathi, ukukhishwa kwe-zinc kungashintsha ukunambitheka nokucaca kwamanzi, futhi amathangi amadala angaba nengozi yokungcoliswa ngomthofu.
Q: Kungani amathangi anamuhla e-galvanized edinga i-liner yangaphakathi ukuze aphuphwe amanzi?
A: Izindonga zangaphakathi (ezifana ne-HDPE yezinga lokudla noma i-epoxy) zisebenza njengesithiyo esibonakalayo phakathi kwamanzi nensimbi. Lokhu kuvimbela i-zinc ion ukuthi ingangeni emanzini, kuvikela igobolondo lensimbi ekugqwaleni ngaphambi kwesikhathi, futhi kuqinisekisa ukuthi amanzi agciniwe ahlangabezana nemithethonqubo eqinile yezempilo yomphakathi.
Q: Ngingazi kanjani ukuthi ithangi lami le-galvanized elikhona liphephile ukuphuza amanzi?
A: Kufanele uhlole ingaphakathi ukuze ubone izimpawu zokuthi kukhona i-polymer liner noma i-coating ekhona. Uma ithangi lingenalo nhlobo i-liner futhi lidala, ungakwazi ukuthi amanzi agciniwe ahlolwe ilabhorethri egunyaziwe ukuze kutholakale izinsimbi ezisindayo (kuhlanganise ne-zinc ne-lead) futhi uxhumane nomkhiqizi mayelana nokuthobela izindinganiso zokuphepha.
Q: Ingabe amathangi ensimbi agalvaniziwe akhipha i-lead emanzini okuphuza?
A: Amathangi ensimbi agalvaniziwe anamuhla akhiqizwa ngokulandela izindinganiso eziqinile zomhlaba wonke zekhwalithi awabeki engcupheni enkulu ye-lead. Kodwa-ke, amathangi agalvaniziwe amadala kakhulu noma asendulo akhiqizwa emashumini eminyaka adlule angase abe nokungcola okuncane kwe-lead ku-zinc coating, okwenza ukuhlolwa kwamanzi noma ukuthuthukiswa kwe-liner kube okubalulekile ezinhlelweni ezindala.
