Imwe ongororo (yakaitwa nekambani yekusefa mvura) inofungidzira kuti vangangosvika 77% yevaAmerica vanoshandisa mvura yemumba yekusefa. Musika wekuUS wekuchenesa mvura (2021) unotarisirwa kukura ne5.85 bhiriyoni pagore. Nehuwandu hwakakura kudaro hwevaAmerica vachishandisa mafirita emvura[1], kutarisisa kukuru kunofanirwa kubhadharwa kumatambudziko ehutano anogona kubuda nekusatsiva sefa yako yemvura.

Iwo mana ekutanga masisitimu anoonekwa seanoshandisa point kurapwa masisitimu nekuti anogadzirisa mvura mumabhechi uye anoitakura kuenda kune imwe pombi. Kusiyana neizvi, iyo yese yedzimba system inoonekwa seyekupinda nzvimbo yekurapa system, iyo inowanzobata yakawanda yemvura inopinda mumba.
Unoda sefa yemvura here?
Vanhu vazhinji vanotenga masefa emvura nekuti vane hanya nekuravira kana kunhuwa, kana nekuti anogona kunge aine makemikari anokuvadza kuutano, senge lead.
Danho rekutanga pakuona kana sefa yemvura ichidiwa kutsvaga panobva mvura yekunwa. Kana mvura yako yekunwa ichibva kune yepakati nepakati kuenda kune yakakura veruzhinji nzira yekupa mvura, ungasada sefa yemvura. Sezvandakambonyora, mazhinji makuru uye epakati-saizi ekupa mvura masisitimu anosangana nemirairo yemvura yekunwa EPA zvakanyanya. Matambudziko mazhinji emvura yekunwa anoitika mumagadzirirwo emvura madiki nematsime ega.
Kana pane kuravira kana kunhuwa nyaya nemvura yako yekunwa, idambudziko neimba yako yepombi dzemvura kana kambani yemvura? Kana dambudziko richingoitika pane mamwe mapombi, inogona kunge iri pombi yako yekumba; Kana mamiriro ezvinhu aya akaitika mumhuri yese, zvinogona kukonzerwa nekambani yako yemvura - ndapota taura navo kana vezvehutano hweveruzhinji munharaunda yako.
Nhau dzakanaka ndedzekuti idzi kuravira uye kunhuwa nyaya kazhinji hazvikonzere matambudziko ehutano. Zvisinei, hapana anofarira kunwa mvura isina kunaka kana kunhuwa, uye mafirita emvura anogona kubatsira zvikuru mukugadzirisa matambudziko aya.
Zvimwe zvezvakajairika kuravira uye kunhuwa nyaya mumvura yekunwa ndezvi:
- Kunhuwa kwesimbi - kazhinji kunokonzerwa nekudonha kwesimbi kana mhangura kubva pamapombi
- Chlorine kana "kemikari" kuravira kana kunhuhwirira - kazhinji kuwirirana pakati peklorini uye organic komisheni mumapaipi masisitimu.
- Sulfur kana zai rakaora kunhuhwirira - kazhinji kubva kunongoitika hydrogen sulfide mumvura yepasi
- Moldy kana kunhuwa kwehove - kazhinji kunokonzerwa nebhakitiriya inokura mumapombi emvura anonyura, zvirimwa, mhuka, kana mabhakitiriya anongoitika mumadziva nemadziva.
- Kuravira munyu - kazhinji kunokonzerwa nehuwandu hwehuwandu hwe sodium, magnesium, kana potasium.
Chikonzero chechipiri chinoita kuti vanhu vatenge mafirita emvura imhaka yekushushikana nezvemakemikari anokuvadza. Kunyange zvazvo EPA inodzora zvinosvibisa makumi mapfumbamwe muhurongwa hwekupa vanhu mvura, vanhu vazhinji havatendi kuti mvura yavo inogona kudyiwa zvisina njodzi pasina mafirita. Chirevo chekuongorora chinoti vanhu vanotenda kuti mvura yakasefa ine hutano (42%) kana kupfuura nharaunda (41%), kana kuti havatendi mumhando yemvura (37%).
dambudziko rehutano
Kusatsiva sefa yemvura kunounza matambudziko ehutano akawanda kupfuura anogadzirisa
Mamiriro ezvinhu aya anoitika nekuti kana sefa ikasatsiviwa nguva nenguva, mabhakitiriya anokuvadza uye mamwe ma microorganisms anokura nekuwanda. Kana mafirita akavharwa, anogona kukuvadzwa, zvichitungamira kuunganidzwa kwebhakitiriya nemakemikari anopinda mumba menyu. Kukura kwakanyanya kwemabhakitiriya anokuvadza kunogona kukuvadza hutano hwako, zvichikonzera matambudziko emudumbu, kusanganisira kurutsa uye manyoka.
Masefa emvura anogona kubvisa makemikari akanaka neakaipa
Masefa emvura haakwanisi kusiyanisa makemikari akakosha kuutano (akadai secalcium, magnesium, iodine, uye potassium) nemakemikari anokuvadza (akadai semutobvu necadmium).
Izvi zvinodaro nekuti kushandisa sefa yemvura kubvisa makemikari kunoenderana nekukura kwepore kwesefa, kunova kukura kwegomba diki rinopfuura nemvura. Fungidzira sefa kana chipunu chinodeuka. Madiki mapores, anovhara madiki anosvibisa. Semuenzaniso, activated carbon filter ine microfiltration filter ine pore size inosvika 0.1 micrometers [2]; Saizi yepore ye reverse osmosis sefa ingangoita 0.0001 micrometers, inogona kuvhara makemikari madiki pane kabhoni mafirita.
Mafirita anogona kuvhara ese makemikari ehukuru hwakafanana, angave akakosha kana anokuvadza kuhutano. Iri rave dambudziko munyika dzakaita seIsrael, uko kuchenesa mvura yegungwa kunoshandiswa zvakanyanya semvura yekunwa. Kubvisa mvura yegungwa kunoshandisa reverse osmosis system kubvisa munyu mumvura, asi kunze kwemunyu, inobvisawo zvinhu zvina zvakakosha: fluoride, calcium, iodine, uye magnesium. Nekuda kwekushandiswa kwakapararira kwekubvisa mvura yegungwa, Israel inobhadhara zvakanyanya kushomeka kweiodine uye kushomeka kwemagnesium muhuwandu. Kushaikwa kweiodine kunogona kukonzera kusashanda kwethyroid, nepo kushomeka kwemagesium kwakabatana nechirwere chemoyo uye mhando 2 chirwere cheshuga.
Vatengi vanoda kuitei?
Hapana mhinduro yekuti sefa yemvura inofanira kutengwa here. Iyi isarudzo yemunhu, zvichienderana nemamiriro ezvinhu emhuri yako. Nyaya dzakanyanya kukosha paunenge uchidzidza mafirita emvura emumba imhando yefirita, saizi yepore, uye zvinosvibisa zvakabviswa.
Mhando huru dzemasefa emvura ndeaya:
Activated kabhoni - ndiyo yakajairika mhando nekuda kwekudhura kwayo uye yakakwirira adsorption rate. Inokodzera kubvisa lead, mercury, uye chlorine, asi haigone kubvisa nitrate, arsenic, heavy metals, kana mabhakitiriya mazhinji.
- Reverse osmosis - kushandisa dzvinyiriro kubvisa tsvina kuburikidza ne semi permeable membrane. Nyanzvi mukubvisa makemikari mazhinji uye mabhakitiriya.
- Ultrafiltration - Yakafanana nekudzorera osmosis, asi haidi simba rekushanda. Inobvisa mamwe makemikari kupfuura reverse osmosis.
- Distillation yemvura - kudziyisa mvura kusvika pakufashaira uyezve kuunganidza mhute yemvura panguva yekunyungudika. Inokodzera kubvisa makemikari mazhinji uye mabhakitiriya.
- Ion exchange filters - shandisa resin ine positive charged hydrogen ions kukwezva zvinosvibisa - kuitira kupfavisa mvura (kubvisa calcium, magnesium, nemamwe mamineral kubva mumvura nekuatsiva ne sodium).
- UV radiation - Yakakwira intensity mwenje inogona kubvisa mabhakitiriya, asi haigone kubvisa makemikari.
Kana uri kufunga kutenga sefa yemvura, unogona kushandisa zvimwe zvakanakisa zviwanikwa:
- Kuti uwane rumwe ruzivo, ndapota shanyira CDC webhusaiti
- Ruzivo rwemhando dzakasiyana dzemasefa emvura
- Product Rating
- Chigadzirwa chetifiketi neNational Health Foundation (NSF), sangano rakazvimirira rinoisa zviyero zvehutano hweveruzhinji kune zvigadzirwa
Kana wakatenga sefa yemvura kana watova neimwe, ndapota yeuka kuitsiva!
