Chaka chatha, panthawi yokonzanso nyumba yanga yatsopano, ndinaika makina oyeretsera madzi pamalo oyamba ngati "ndalama zogulira thanzi." Ndinachita homuweki yanga, ndinafunsa makampani atatu, ndipo pamapeto pake ndinagwiritsa ntchito pafupifupi $10,000 pa makina apamwamba otchedwa reverse osmosis (RO) omwe amadziwika kuti ndi "osefera magawo asanu ndi awiri, olumikizidwa mwanzeru, komanso otetezeka kwa ana." Nditakhazikitsa, nditayang'ana chiwonetsero cha TDS cha nthawi yeniyeni chikutsika kufika pa manambala amodzi, ndinamva kuti ndalamazo zinagwiritsidwa ntchito bwino.

Patatha miyezi isanu ndi umodzi, mavuto anayamba kuonekera ngati kutuluka pang'onopang'ono. Nazi mavuto omwe ndinalowamo, kuti muwapewe.

Phunziro 1: Mtundu wa Membrane Ndi Wofunika Kwambiri Kuposa Nambala ya “800 GPD”

Ndinali ndi cholinga chimodzi: kuchuluka kwa madzi. Wogulitsa anati, “Pezani 800 GPD (magaloni patsiku). Kuthamanga kwambiri, kudzaza mwachangu, komanso kosatha mtsogolo.” Ndinakhulupirira. Inde, imadzaza galasi mwachangu. Koma sindinafunsepo funso lofunika kwambiri: Ndani amapanga nembanemba ya RO mkati?
Pambuyo pake ndinazindikira kuti pali opanga ma RO membrane ochepa kwambiri padziko lonse lapansi, monga Dow Filmtec, Hydranautics, ndi GE. Nditatsegula chipangizo changa, nyumba ya membraneyo inali ndi chizindikiro chosadziwika cha OEM.
Chowonadi Chovuta: Kuthamanga kwa madzi (GPD) kumatsimikiza liwiro, koma mtundu wa nembanemba umatsimikiza mphamvu yoyeretsera madzi ndi moyo wake. Nembanemba ya 800 GPD yochokera kwa wopanga wachitatu ikhoza kukhala ndi kuchuluka kochepa kokana mchere, kukhazikika, komanso kukana kuipitsidwa ndi madzi kuposa nembanemba ya 400 GPD yochokera ku kampani yapamwamba. Nthawi zonse funsani mtundu ndi nambala yeniyeni ya nembanemba ya RO polemba, ndipo pezani chitsimikizo chakuti mtundu/spec yomweyi idzakhalapo kuti isinthidwe mtsogolo.

Phunziro 2: Zinthu “Zanzeru” Zingakhale Msampha Wopusa

Makina anga olumikizidwa ku pulogalamu. Kwa miyezi itatu yoyambirira, zinali zosangalatsa: Ndinkatha kuwona TDS, kuchuluka kwa moyo wa fyuluta, ndi momwe madzi amagwiritsidwira ntchito tsiku ndi tsiku. Koma ndizo zonse. "Luntha" ili linali kufalitsa deta ya njira imodzi.

• Nthawi yogwiritsira ntchito zosefera inali yowerengera nthawi yosavuta, osati kuwerengera kutengera mtundu weniweni wa madzi kapena kuchuluka kwa momwe amagwiritsidwira ntchito. Nthawi yogwiritsira ntchito inali yowerengera ngati tidagwiritsa ntchito madzi kapena ayi.
• Inandiuza kuti ndisinthe fyuluta ya sediment yoyamba, koma nditatsegula chipinda choyera, fyulutayo inali yoyera ngati chipale chofewa, palibe pafupi ndi kusintha kwa mtundu wa bulauni komwe kumafunika.
• Choyipa kwambiri chinali alamu yabodza. Pulogalamuyo nthawi ina inachenjeza mwachangu kuti "MADZI AKUSAKHALA OSAKHALA OKHA," zomwe zinasonyeza kuti TDS yakwera kufika pa 80. Banja langa linali ndi nkhawa kwa maola ambiri. Kukonzanso kwakutali kwa chithandizo cha makasitomala kunakonza vutoli. Mainjiniya pambuyo pake anati mwina linali vuto la sensor yosakhalitsa kapena cholakwika chotumizira deta. Alamu imodzi yabodza ingawononge chidaliro chonse.
  Choonadi Chovuta: Samalani ndi "nzeru chifukwa cha anzeru." Nzeru yeniyeni imatanthauza kugwiritsa ntchito masensa angapo (kuyenda, kuthamanga, TDS yosiyana) kuti muwerengere molondola kutopa kwa fyuluta ndikuphunzira momwe banja lanu limagwiritsira ntchito. Kubwezeretsa nthawi kosavuta pamanja kumakhala kodalirika kuposa kosokeretsa kwa digito.

Phunziro 3: Ukadaulo wa “Madzi Osakhazikika”: Kutsatsa Kwambiri Kapena Zogulitsa Zenizeni?

Chipangizo changa chinalengeza za ukadaulo wa “Zero Stagnant Water” kapena “First Glass Drinkable”. Mfundo yake ndi yakuti: pambuyo pa nthawi yopuma, makinawa amatsuka nembanemba ya RO ndi madzi oyera kuti achepetse kuipitsidwa kwambiri, kotero galasi loyamba la m'mawa silikhala ndi TDS yochuluka. Zikumveka bwino.
Zoona zake: Galasi langa loyamba la m'mawa linali ndi ma TDS pafupifupi 30 (bwino kwambiri kuposa 100+ popanda mawonekedwe), koma linali lalikulu kwambiri kuposa 5 TDS yokhazikika. Kuphatikiza apo, kuti izi zitheke, makinawo ankayendetsa okha kangapo patsiku ndi usiku. Ndinkamva phokoso lochepa la kusamba ndi phokoso la pompu pakati pausiku.
Zoona Zovuta: "Madzi Osakhazikika Opanda Mphamvu" ndi kusintha, osati chozizwitsa. Musayembekezere kuti madzi otuluka usiku wonse akhale ofanana ndi atsopano. Funsani wogulitsayo kuti akupatseni zizindikiro ziwiri zenizeni: 1) Kodi TDS ya galasi loyamba pambuyo pa kuzimitsa kwa maola 4 ndi chiyani? 2) Kodi izi zimafuna ma cycle angati odzitsuka okha patsiku, ndipo madzi angati amawonongeka? Kuzengereza ndi chizindikiro choopsa.

Phunziro 4: Ndalama Zosefera Ndi Zotentha Mosachedwetsa

Wogulitsayo analonjeza kuti: “Zosefera ndi zotsika mtengo, pafupifupi dola imodzi patsiku!” Sanali kunama—anali kunena mtengo wapakati wa fyuluta yotsika mtengo kwambiri ya sediment first-stedity filter ($99 / miyezi 6).
Pamene nthawi yosinthira fyuluta yonse inafika, ndalama yeniyeni inafika:

• Fyuluta ya Sediment ya Gawo 1: $99
• Fyuluta ya Carbon ya Gawo 2: $199
• Chingwe cha RO cha Gawo 3 (dzina lopanda dzina): $899
• Fyuluta ya Gawo 4 Pambuyo pa Mpweya: $159
  Zonse pa seti imodzi: $1,356. Ndipo ndondomeko yosinthira? Nembanemba ya RO zaka 2-3 zilizonse, zina miyezi 6-12 iliyonse. Iyi ndi ndalama yayikulu, yobwerezabwereza. Choyipa kwambiri n'chakuti, awa anali makatiriji enieni, omwe amandiletsa kulowa mu kampani popanda njira zina za chipani chachitatu.
  Zoona Zenizeni: Musanagule, MUYENERA kufufuza manambala a mtundu ndi mitengo yogulitsira zosefera ZONSE patsamba lovomerezeka la kampaniyi. Werengani mtengo wonse wa zaka zitatu wa umwini. "Mtengo wa moyo wonse" uwu ndi wofunika kwambiri kuposa mtengo wa sticker wa makinawo.

Phunziro 5: Utumiki Ndi Wosaoneka Mpaka Utapsa

Kukhazikitsa kunali bwino. Vutoli linayamba Loweruka usiku. Makinawo anasiya kutulutsa madzi popanda khodi yolakwika. Nambala ya 400-service inapangitsa kuti atumize uthenga wa AI. Katswiri wina wa m'deralo sanayimbe foni mpaka Lamlungu masana, nati akhoza kubwera Lolemba lokha. Tinakhala kumapeto kwa sabata opanda madzi oyera.
Katswiri anabwera Lolemba, anasewera kwa mphindi 30, ndipo anati "valavu ya solenoid yolowera inali kugwira ntchito." Anayigwira, ndipo inagwira ntchito. Ndinafunsa kuti inagwiranso ntchito kwa nthawi yayitali bwanji. Anamwetulira, "N'zovuta kunena. Koma sitisunga zida zambiri za mtundu uwu m'deralo. Kusintha kungatenge masiku 3-4 kuchokera ku likulu."
Kuzizira kunandigwera msana. Kodi zida zosungiramo zinthu zapafupi—za “mtima” (pampu/nembanemba) ndi “ma valavu” (ma valavu)—zilipodi? Wogulitsa sanatchulepo izi.
Zoona Zovuta: Musanasainire, fufuzani momwe ntchito yanu ilili. Funsani kuti mudziwe ngati malo operekera chithandizo ali ndi kulumikizana mwachindunji ndi kampani yopereka chithandizo. Imbani foni ndi funso loti mukonze kuti mudziwe nthawi yomwe akuyankha komanso zomwe akudziwa. Chotsukira chapamwamba chopanda chithandizo chachangu komanso chaluso chimangokhala bokosi lolemera, lotayikira likasweka.

Phunziro langa la $10,000 silinali lokhudza madzi okha. Linali lokhudza kuyang'ana kupitirira zinthu zapamwamba komanso kufunsa mafunso osasangalatsa komanso othandiza okhudza zigawo zazikulu, nzeru zenizeni, magwiridwe antchito enieni, ndalama zogulira nthawi yayitali, ndi njira zogwirira ntchito. Chotsukira chanu ndi mnzanu wa nthawi yayitali pa thanzi lanu. Sankhani chimodzi chomangidwa pa kuwonekera bwino, osati malonda okha.
