TDS. RO. GPD. NSF 53. Ukuba wakha waziva ngathi udinga isidanga sesayensi ukuze uqonde iphepha lemveliso yomatshini wokucoca amanzi, awuwedwa. Izixhobo zokuthengisa zihlala zivakala ngathi zithetha ngekhowudi, nto leyo eyenza kube nzima ukwazi ukuba uthenga ntoni ngokwenene. Masichaze amagama aphambili ukuze ukwazi ukuthenga ngokuzithemba.

Okokuqala, Kutheni Oku Kubalulekile?

Ukwazi ulwimi akubhekiselele ekubeni yingcali kwezobuchwepheshe. Kuxhomekeke ekunqandeni uthuli lokuthengisa ukuze ubuze umbuzo olula: “Ngaba lo matshini uza kuzisombulula iingxaki ezithile ngemyamanzi?” La magama zizixhobo zokufumana impendulo yakho.

Icandelo 1: Ii-Acronyms (Ii-Core Technologies)

• I-RO (i-Reverse Osmosis): Le yindlela yokuphakamisa izinto ezinzima. Cinga nge-membrane ye-RO njengesihluzo esincinci kakhulu apho amanzi atyhalwa khona phantsi koxinzelelo. Isusa phantse zonke izinto ezingcolisayo, kuquka iityuwa ezinyibilikisiweyo, iimetali ezinzima (ezifana nelothe), iintsholongwane kunye neebhaktheriya. Inzuzo kukuba ikwasusa iiminerali eziluncedo kwaye ichitha amanzi athile kule nkqubo.
• I-UF (i-Ultrafiltration): I-UF membrane ithambile kune-RO. I-UF membrane ineembobo ezinkulu. Ilungele ukususa amasuntswana, umhlwa, iibhaktheriya kunye nee-cysts, kodwa ayinakususa iityuwa ezinyibilikisiweyo okanye iimetali ezinzima. Ifanelekile kumanzi acociweyo ngumasipala apho injongo ephambili kukuphucula incasa kunye nokhuseleko ngaphandle kokuchithwa kwenkqubo ye-RO.
• I-UV (i-Ultraviolet): Le ayisiyonto yokucoca; sisibulali-ntsholongwane. Ukukhanya kwe-UV kutshabalalisa iintsholongwane ezifana neebhaktheriya kunye neentsholongwane, kutshabalalisa i-DNA yazo ukuze zingakwazi ukuzala. Ayinampembelelo kwiikhemikhali, kwiisinyithi, okanye kwiincasa. Phantse isetyenziswa rhoqongokudibeneyokunye nezinye izihluzi zokubulala iintsholongwane zokugqibela.
• I-TDS (Izinto Ezinyibilikisiweyo Zizonke): Olu luvavanyo, hayi ubuchwepheshe. Iimitha ze-TDS zilinganisa uxinaniso lwazo zonke izinto ezingaphiliyo neziphilayo ezinyibilikiswe emanzini akho—ikakhulu iiminerali kunye neetyuwa (i-calcium, i-magnesium, i-potassium, i-sodium). I-TDS ephezulu (masithi, ngaphezulu kwe-500 ppm) idla ngokuthetha ukuba udinga inkqubo ye-RO ukuphucula incasa kunye nokunciphisa isikali. Ingqiqo ephambili: Ukufundwa kwe-TDS ephantsi akuthethi ngokuzenzekelayo ukuba amanzi akhuselekile—asenokuba neebhaktheriya okanye iikhemikhali.
• I-GPD (Iilitha Ngemini): Olu luvavanyo lomthamo. Lukuxelela ukuba zingaphi iilitha zamanzi acocekileyo inkqubo enokuzivelisa kwiiyure ezingama-24. Inkqubo ye-50 GPD ilungile kwisibini, kodwa usapho lwabantu abane lunokufuna i-75-100 GPD ukuze lungalindeli ukuba itanki lizaliswe kwakhona.

Icandelo 2: Iziqinisekiso (Iimpawu zeTrust)

Le yindlela oqinisekisa ngayo amabango enkampani. Musa ukukholelwa nje ukuba ayithethi loo nto.

• Imigangatho ye-NSF/ANSI: Le yimigangatho yegolide. Isiqinisekiso se-NSF esizimeleyo sithetha ukuba imveliso ivavanyiwe ngokwasemzimbeni kwaye ingqiniwe ukuba iyanciphisa ungcoliseko oluthile.
  • I-NSF/ANSI 42: Iqinisekisa isihluzi kunciphisa i-chlorine, incasa, kunye nevumba (iimpawu zobuhle).
  • I-NSF/ANSI 53: Iqinisekisa isihluzo kunciphisa izinto ezingcolisa impilo ezifana ne-lead, i-mercury, i-cysts, kunye ne-VOCs.
  • I-NSF/ANSI 58: Umgangatho othile weenkqubo ze-Reverse Osmosis.
• I-WQA Gold Seal: Isiqinisekiso se-Water Quality Association sikwaluphawu oluhloniphekileyo, olufana ne-NSF.
• Okufanele ukwenze: Xa uthenga, khangela uphawu oluchanekileyo lwesatifikethi kunye nenombolo kwimveliso okanye kwiwebhusayithi. Ibango elingacacanga elifana nelithi “liyahlangabezana nemigangatho ye-NSF” alifani nokuba uqinisekiswe ngokusemthethweni.

Icandelo 3: Amagama Aqhelekileyo (Kodwa Adidayo)

• Amanzi e-Alkaline/Mineral: Ezinye izihluzi zongeza iiminerali kwakhona kumanzi e-RO okanye zisebenzisa iiceramics ezikhethekileyo ukunyusa i-pH (okwenza ingabi ne-asidi eninzi). Iingenelo zempilo ezithiwayo ziyaxoxwa, kodwa abantu abaninzi bakhetha incasa.
• I-ZeroWater®: Eli ligama lophawu lweepitchers ezisebenzisa isihluzo esinezigaba ezi-5 kuquka i-ion-exchange resin, egqwesileyo ekunciphiseni i-TDS kumanzi acocekileyo kakhulu. Izihluzo zazo zihlala zifuna ukutshintshwa rhoqo kwiindawo ezinamanzi aqinileyo.
• Ukuhluzwa kweSigaba (umz., iSigaba sesi-5): Izigaba ezingaphezulu azingcono ngokuzenzekelayo. Zichaza izinto ezahlukeneyo zesihluzo. Inkqubo eqhelekileyo ye-RO yesigaba sesi-5 inokuba yile: 1) Isihluzo seSediment, 2) Isihluzo seCarbon, 3) i-RO membrane, 4) Isihluzo seCarbon post-filter, 5) Isihluzo seAlkaline. Qonda ukuba inqanaba ngalinye lenzani.

Iphepha lakho lokukhohlisa elinokuphazamisa iJargon ukuze ulithenge

1. Vavanya Kuqala. Fumana imitha ye-TDS elula okanye umgca wovavanyo. Iiminerali/i-TDS eziphezulu? Kusenokwenzeka ukuba ungumviwa we-RO. Ufuna nje incasa/ivumba elingcono? Isihluzi sekhabhoni (NSF 42) sinokwanela.
2. Dibanisa isiqinisekiso neNgxaki. Ukhathazekile ngelothe okanye iikhemikhali? Jonga kuphela iimodeli ezine-NSF/ANSI 53 okanye 58. Musa ukuhlawulela inkqubo eqinisekisiweyo yezempilo ukuba ufuna ukuphucula incasa.
3. Musa ukungazihoyi iiBango ezingacacanga. Musa ukulibala "ukususa ityhefu" okanye "ukunika amandla." Gxila ekunciphiseni ungcoliseko oluthile noluqinisekisiweyo.
4. Yenza izibalo zomthamo. Inkqubo ye-50 GPD ivelisa malunga neelitha eziyi-0.035 ngomzuzu. Ukuba ukuzalisa ibhotile yelitha e-1 kuthatha imizuzwana engaphezu kwama-45, yiloo nto uyifunayo. Khetha i-GPD ehambelana nomonde wakho.
