Iyini Ithangi Yamanzi Okuphuza? | Umhlahlandlela Wokuphepha, Amazinga, Nokwakhiwa
Ithangi lamanzi okuphuza (potable water tank) iyisitsha esikhethekile, esakhiwe ngobunjiniyela ukuze sigcine amanzi ahloselwe ukusetshenziswa ngabantu. Ngokungafani nezitsha ezijwayelekile zokugcina uketshezi, amathangi amanzi okuphuza alawulwa yimithetho eqinile yezempilo nokuphepha yamazwe ngamazwe—ikakhulukazi i-NSF/ANSI/CAN 61—emisa ukuthi zonke izindawo zangaphakathi, izinto zokuvala, amagaskethi, nezinto zokubopha kufanele zingakwazi ukusabela ngamakhemikhali futhi zingakhiphi izinto ezinobuthi. Lawa mathangi ayizingxenye ezibalulekile zengqalasizinda yezinhlelo zamanzi zomasipala, ezohwebo, nezemboni, edinga ubuchwepheshe obuthuthukile bezinto zokwakha ukuze kuvinjwe ukukhula kwamagciwane (i-biofilm), kuvinjwe ukugqwala, futhi kuqinisekiswe ukuqina kwesakhiwo sesikhathi eside komthamo wamanzi okuphuza.
Umehluko "Ophuzwayo": Kungani Amazinga Abalulekile
Emkhakheni wamanzi wezimboni, ukubeka ithangi ukuthi "liyaphuza" akukona ukukhetha kokumaketha; kuyisimiso esimisiwe. Umkhumbi ufaneleka kuphela emanzini okuphuza uma uvika ukunikezwa ekungcoleni nasekonakaleni kwesakhiwo isikhathi esingaphezu kweminyaka engu-30.
● Ukuthobela Izinga Lohlelo: Ithangi liphephile ngokulingana nengxenye yalo ebuthaka. Ukuthobela i-NSF/ANSI 61 kusebenza kuyo yonke inhlangano. Uma usebenzisa amaphaneli aqinisekisiwe kodwa izinto zokunamathisela noma izikulufu ezingaqinisekisiwe, lonke uhlelo luyehluleka ukuhlangabezana nezinga.
● Ukuvimbela Ukuchitheka Kokungcolisa: Amathangi aqinisekisiwe enza "ukuhlolwa kokucwilisa" okuqinile kusetshenziswa amakhemikhali amanzi alingisa izimo ezinzima (ukuhluka kwe-pH namazinga okushisa) ukuze kuqinisekiswe ukuthi izinto ezisetshenziswayo azikhiphi izinsimbi ezinzima noma ama-VOC emanzini.
● Ukuphepha Kwezinto Eziphilayo & Ukulawula Ukukhanya: Amathangi amanzi aphuzwayo aklanyelwe ukungaboni ngempela. Ukungena kokukhanya kwelanga kukhuthaza ukukhula kwe-algae ne-biofilm; ngokugcina ingaphakathi libumnyama ngokuphelele, umklamo wethangi uvimbela ngokwemvelo ukwakheka kwamagciwane athwalwa ngamanzi.
Ukuqhathanisa Izinto Zokwakha: Ukukhetha Ingqalasizinda Efanele
Lapho kucaciswa ithangi, onjiniyela kumele balinganise inhlanzeko, ukuphila isikhathi eside kwesakhiwo, nezidingo zokunakekela.
Isici | Ingilazi Ehlanganiswe Nensimbi (GFS) | Insimbi Engagqwali | Ukakhonkolo Oqinisiwe | Ipulasitiki (HDPE) |
Inhlanzeko/Ukuphepha | Kuhle Kakhulu (Akusebenzi) | Kuhle Kakhulu (Akusebenzi) | Kulingene (Idinga i-Liner) | Kuhle (Izinga Lokudla) |
Ukuqina | Iminyaka Engu-30+ | Iminyaka Engu-30+ | Iminyaka Engu-20–40 | Iminyaka Engu-10–20 |
Ukunakekela | Okuncane Kakhulu | Okuphansi | Okuphezulu (Imifantu/Umugqa Ongaphakathi) | Okulingene |
Ukukhula | Okuphezulu (Okwenziwa ngeziqeshana) | Okulingene | Okuphansi (Kuncike endaweni) | Okuphansi Kakhulu |
Qaphela: I-Glass-Fused-to-Steel (GFS) ivame ukukhethwa njengebhentshimaki yemboni yokugcina amanzi aphuzwayo kamasipala nezimboni ngoba ihlanganisa amandla esakhiwo sensimbi nenhlanzeko ephelele yobuso bengilazi ebunjiweyo engagqwali noma ikhihle.
Izici Ezibalulekile Zobunjiniyela
Ukuze kugcinwe ikhwalithi yamanzi isikhathi esiyiminyaka engu-30 yokuphila, ithangi elihleliwe lokuphuza amanzi kufanele lihlanganise:
1. I-Jiyomethri Yokuzihlanza: Umklamo waphansi kufanele wenze kube lula ukukhipha amanzi ngokuphelele ukuze kugwenywe ukunqwabelana kwezibi nezindawo "ezifile" lapho amanzi angamile khona.
2. Umoya Osebenza Kahle Kakhulu: Izimbobo zomoya kufanele zifakwe izikrini ezingenwa izinambuzane kanye nokuhlunga ukuze kuvumele ukushintshana komoya ngesikhathi sokushintsha kwezinga lamanzi ngaphandle kokungenisa uthuli, impova, noma izinambuzane.
3. Ukuvimbela Ukugqwala: Emathangini ensimbi, ingaphakathi kufanele linamathele ngokuphelele futhi lingabi namaholide. Lokhu kuqinisekisa ukuthi ayikho insimbi eluhlaza eveziwe emanzini, kuvinjelwe ukungcola okubangelwa ukugqwala.
4. Izindinganiso Zesakhiwo: Amathangi kufanele ahlangabezane nezindinganiso eziqinile zesakhiwo (ezifana ne-AWWA D103) ukuze amelane nokuzamazama komhlaba, imithwalo yomoya enamandla, nengcindezi yangaphakathi yamanzi.
Imibuzo Evame Ukubuzwa (FAQ)
Q: Ngingasebenzisa ithangi elenzelwe amanzi ezimboni ukuze ngithole amanzi okuphuza?
A: Cha. Ngaphandle uma ithangi ligunyazwe ngokusobala ukuthi lihambisana nezindinganiso ze-NSF/ANSI 61, alikwazi ukusetshenziselwa amanzi okuphuza. Amathangi ezimboni angase asebenzise izinto zokumboza noma izinto zokuhlanganisa eziphephile emanzini angcolile noma ezinqubweni zamakhemikhali kodwa zikhiphe amakhemikhali ayingozi emanzini okuphuza.
Q: Kufanele amathangi amanzi okuphuza ahlolwe kangaki?
A: Umkhuba ojwayelekile wokulawula uphakamisa ukuhlolwa kwangaphakathi okungenani kanye njalo eminyakeni emi-3 kuya kwemi-5. Lokhu kuhlola ukunqwabelana kwesidumbu, ubuqotho bokumbozwa, kanye nesimo sezivalo nama-gasket.
Q: Ingabe ipulasitiki "ye-Food-Grade" iyafana nesitifiketi se-NSF 61?
A: Cha. Nakuba "i-food-grade" ikhombisa ukuthi into ayinabo ubuthi, i-NSF 61 iwukuhlolwa okuqinile, okuqondile okuhlola ukuthi amakhemikhali asuka entweni angena kanjani emanzini ngaphansi kwezimo ezihlukahlukene. Hlala udinga imibhalo efakazela isitifiketi se-NSF 61 kulo lonke uhlelo lwethangi.
Cela Isilinganiso (RFQ): Yakha Uhlelo Lwakho Lwamanzi Okuphuza
Ingqalasizinda yamanzi okuphuza iyisisekelo sempilo yomphakathi neyezimboni. Uma ucacisela amathangi e-gridi kamasipala, ukuthuthukiswa kwezindawo zokuhlala, noma indawo yezimboni, udinga isixazululo esiqinisekisa inhlanzeko nokuthobela imithetho yesikhathi eside.
Ukuze uthole ukuhlolwa kwesakhiwo okwenziwe ngokwezidingo zakho kanye nesilinganiso sesabelomali, sicela unikeze:
● Umthamo Ophelele OdIngekayo: (Umthamo ngemitha3 noma amagalani).
● Izidingo Zemithetho: (isb., isitifiketi se-NSF/ANSI 61, i-AWWA D103, amakhodi ezempilo endawo).
● Indawo Yesiza: (Indawo, izimo zezulu ezinzima, kanye nezici zokuzamazama komhlaba/umoya).
● Izidingo Zokuhlanganisa: (Izindawo zemibhobho, izinhlelo ezikhethekile zamaladi, noma ukuqapha okuzenzakalelayo).
Uyayidinga ukubuyekezwa kwezobuchwepheshe? [Xhumana nethimba lethu lobunjiniyela] ukuze uthole ukubonisana kochwepheshe mayelana nobukhulu bethangi, ukuthotshelwa kokuphepha kwezinto, noma ukwakheka kwesakhiwo sephrojekthi yakho yamanzi okuphuza.
