Ngonyaka odlule, ngesikhathi ngilungisa ikhaya lami elisha, ngabeka umshini wokuhlanza amanzi endaweni yokuqala “njengotshalomali lwezempilo.” Ngenza umsebenzi wami wesikole, ngabonisana nemikhiqizo emithathu, futhi ekugcineni ngasebenzisa cishe u-$10,000 ohlelweni oluphezulu lwe-reverse osmosis (RO) olubizwa ngokuthi “ukuhlunga okunezigaba eziyisikhombisa, okuxhunywe ngobuhlakani, futhi okuphephile ezinganeni.” Ngemva kokufakwa, ngibuka isibonisi se-TDS sesikhathi sangempela sehla saba izinombolo ezilodwa, ngaba nomuzwa wokuthi imali yayisetshenziswe kahle.

Ngemva kwezinyanga eziyisithupha, izinkinga zaqala ukuvela njengokuvuza kancane kancane. Nazi izingibe engangena kuzo, ukuze uzigweme.

Isifundo 1: Uhlobo Lolwelwesi Lubaluleke Kakhulu Kunenombolo “ye-800 GPD”

Ngangigxile ku-spec eyodwa: izinga lokugeleza. Umthengisi wathi, “Thola i-800 GPD (amagaloni ngosuku). Ukugeleza okuphezulu, ukugcwalisa okusheshayo, okuvikela ikusasa.” Ngakukholwa. Impela, kugcwalisa ingilazi ngokushesha. Kodwa angikaze ngibuze umbuzo obalulekile: Ubani okhiqiza i-RO membrane ngaphakathi?
Kamuva ngathola ukuthi bambalwa kakhulu abakhiqizi be-RO membrane abasezingeni eliphezulu emhlabeni wonke, njengeDow Filmtec, Hydranautics, kanye ne-GE. Lapho ngivula iyunithi yami, indlu ye-membrane yayinesitembu esingaziwa somkhiqizo we-OEM.
Iqiniso Eliqinile: Izinga lokugeleza (i-GPD) linquma isivinini, kodwa uphawu lwe-membrane lunquma ukusebenza kahle kokuhlanzwa kwe-core kanye nesikhathi sokuphila. I-membrane engu-800 GPD evela kumkhiqizi wesigaba sesithathu ingaba namazinga aphansi kakhulu okwenqatshwa kosawoti, ukuzinza, kanye nokumelana nokungcola kune-membrane engu-400 GPD evela kumkhiqizo ophezulu. Njalo funa uhlobo oluthile lomkhiqizo kanye nenombolo yemodeli ye-membrane ye-RO ngokubhala, bese uthola isiqinisekiso sokuthi uhlobo/i-spec efanayo izotholakala ukuze kufakwe ezinye esikhundleni esikhathini esizayo.

Isifundo 2: Izici “ezihlakaniphile” zingaba ugibe oluyisiwula

Umshini wami uxhunywe kuhlelo lokusebenza. Ezinyangeni ezintathu zokuqala, kwakuzwakala kupholile: Bengikwazi ukubona i-TDS, iphesenti lokuphila kwesihlungi, kanye nokusetshenziswa kwamanzi nsuku zonke. Kodwa kwaphela lokho. Lokhu "kuhlakanipha" kwakuwukusakaza idatha ngendlela eyodwa kuphela.

• Impilo yokuhlunga yayiyisikhathi esilula sokubala phansi, esingabalwanga ngokusekelwe kwikhwalithi yangempela yamanzi noma ivolumu yokusetshenziswa. Isikhathi sasibala ukuthi ngabe sisebenzise amanzi noma cha.
• Yangitshela ukuthi ngishintshe isihlungi sesediment sesigaba sokuqala, kodwa lapho ngivula indawo ecacile, isihlungi sasisemhlophe njengeqhwa, singekho eduze kokushintsha kombala onsundu okudingekayo.
• Okubi kakhulu kwakuyi-alamu engamanga. Uhlelo lokusebenza lwakhe lwaxwayisa ngokuphuthumayo ngokuthi “IKHWALITHI YAMANZI AYINGEYONA EJWAYELEKILE,” okubonisa ukwenyuka kwe-TDS ku-80. Umndeni wami wawukhathazekile amahora amaningi. Ukusetha kabusha okukude kwesevisi yamakhasimende kwakulungisa. Kamuva unjiniyela wathi kungenzeka ukuthi kwakuyiphutha le-sensor yesikhashana noma iphutha lokudlulisa idatha. I-alamu eyodwa engamanga ingaqeda konke ukwethembana.
  Iqiniso Elinzima: Qaphela "ukuhlakanipha ngenxa yokuhlakanipha." Ukuhlakanipha kweqiniso kusho ukusebenzisa izinzwa eziningi (ukugeleza, ingcindezi, i-TDS ehlukile) ukuze ubale ngokunembile ukukhathala kwesihlungi futhi ufunde amaphethini okusetshenziswa komndeni wakho. Ukusetha kabusha isikhathi ngesandla okulula kunokwethenjelwa kakhulu kunokwedijithali okudukisayo.

Isifundo 3: Ubuchwepheshe “Bamanzi Angaguquki”: Ukumaketha Okumangalisayo Noma Isivumelwano Sangempela?

Iyunithi yami ikhangise ubuchwepheshe be-“Zero Stagnant Water” noma “First Glass Drinkable”. Isimiso: ngemva kwezikhathi zokungasebenzi, uhlelo luhlanza ulwelwesi lwe-RO ngamanzi ahlanzekile ukuze kuncishiswe ukungcola okugxilile, ngakho ingilazi yokuqala yasekuseni ayiphezulu kangako ku-TDS. Kuzwakala kukuhle.
Iqiniso: Ingilazi yami yokuqala yasekuseni yayilinganisa cishe ama-TDS angu-30 (angcono kakhulu kune-100+ engenaso isici), kodwa yayisaphakeme kakhulu kune-TDS engu-5 ezinzile. Ngaphezu kwalokho, ukuze kufezwe lokhu, umshini wawuzijikeleza ngokuzenzakalelayo izikhathi eziningana ngosuku nasebusuku. Ngangizwa "ukuguguleka" okuncane kokuhlanza nokupompa umsindo phakathi kwamabili.
Iqiniso Elinzima: “Amanzi Angaguquki” ayintuthuko, hhayi isimangaliso. Ungalindeli ukuthi amanzi aphuzwa ebusuku afane namanzi amasha. Buza umthengisi ngemininingwane emibili eqondile: 1) Iyini i-TDS yengilazi yokuqala ngemva kokuvala amahora angu-4? 2) Zingaki imijikelezo yokuzihlanza ngokuzenzakalelayo ngosuku lokhu okudingayo, futhi angakanani amanzi achithekayo? Ukungabaza kuyisibonakaliso esibomvu.

Isifundo 4: Izindleko Zokuhlunga Ziyashesha Kancane, Zithule

Umthengisi wathembisa: “Izihlungi zishibhile, zilinganiselwa ngaphezu kwedola elilodwa ngosuku!” Wayengaqambi amanga—wayecaphuna izindleko ezimaphakathi zesihlungi sedaka sesigaba sokuqala esishibhile ($99 / izinyanga ezi-6).
Lapho kufika isikhathi sokushintsha isihlungi esigcwele, ibhili langempela lafika:

• Isihlungi se-Sediment seSigaba 1: $99
• Isihlungi sekhabhoni sesigaba sesi-2: $199
• I-Stage 3 RO Membrane (uphawu olungenalo igama): $899
• Isihlungi se-Stage 4 Ngemuva kwe-Carbon: $159
  Isiyonke sesethi eyodwa: $1,356. Futhi uhlelo lokushintsha? I-RO membrane njalo eminyakeni emi-2-3, eminye njalo ezinyangeni ezi-6-12. Lokhu kuyindleko enkulu, ephindaphindayo. Okubi nakakhulu, lawa kwakungama-cartridge azimele, angivalela kumkhiqizo ngaphandle kwezinketho zomuntu wesithathu.
  Iqiniso Elinzima: Ngaphambi kokuthenga, KUMELE ucwaninge izinombolo zamamodeli kanye namanani okuthengisa azo ZONKE izihlungi zokufaka esikhundleni kusayithi elisemthethweni lomkhiqizo. Bala izindleko zobunikazi zeminyaka emi-3. Lezi "zindleko zokuphila konke" zibaluleke kakhulu kunentengo yesitikha somshini.

Isifundo 5: Inkonzo Ayibonakali Kuze Kube Usufile

Ukufakwa kwahamba kahle. Inkinga yafika ngoMgqibelo ebusuku. Umshini wayeka ukukhipha amanzi ngaphandle kwekhodi yephutha. Inombolo yesevisi engu-400 yaholela ezwini le-AI. Uchwepheshe wendawo akazange ashaye ucingo kwaze kwaba yiSonto emini, ethi angafika ngoMsombuluko kuphela. Sichithe impelasonto singenawo amanzi ahlanzekile.
Uchwepheshe weza ngoMsombuluko, wadlala imizuzu engama-30, wathi “i-inlet solenoid valve yayinamathela.” Wayithinta, yasebenza. Ngabuza ukuthi izophinde yehluleke isikhathi esingakanani. Wamomotheka, “Kunzima ukusho. Kodwa asigcini izingxenye eziningi zalolu hlobo endaweni. Ukufakwa esikhundleni kuzothatha izinsuku ezi-3-4 ukusuka endlunkulu.”
Kwaba nokugodola emgogodleni wami. Ingabe izingxenye ezisele zendawo—zenhliziyo (ipompo/ulwelwesi) kanye “namalunga” (ama-valve)—zikhona ngempela esitokweni? Umthengisi akakaze akhulume ngalokhu.
Iqiniso Elinzima: Ngaphambi kokusayina, hlola amandla esevisi yendawo. Cela ukuxhumana ngqo nesikhungo sesevisi sendawo. Bashayele ucingo ngombuzo wokulungisa ocatshangelwayo ukuze ulinganise isikhathi sabo sokuphendula nolwazi. Isihlanzi sekhwalithi ephezulu esingenasevisi esheshayo nenekhono simane nje siyibhokisi elisindayo, elivuzayo lapho liphuka.

Isifundo sami samaRandi ayi-10,000 sasingesiwo amanzi kuphela. Sasimayelana nokubheka ngale kwemininingwane ekhangayo nokubuza imibuzo eyisicefe nesebenzayo mayelana nezingxenye eziyinhloko, ubuhlakani beqiniso, ukusebenza kwangempela, izindleko zesikhathi eside, kanye nezinsizakalo zokuphila. Isihlanzi sakho singumlingani wesikhathi eside empilweni yakho. Khetha esakhelwe phezu kokubonakala, hhayi ukumaketha kuphela.
