NSF Yemewe Amazi Akayunguruzo: Uburyo bwizewe kandi bwizewe bwo gushungura amazi meza
Muri societe yiki gihe, kureba neza ko amazu nubucuruzi bishobora kubona amazi meza, meza yo kunywa ni ngombwa. Hariho ubwoko bwinshi bwiyungurura kuburyo bishobora kugorana kuvuga imwe ikora. Aha niho icyemezo cya NSF gihinduka igipimo cyingenzi cyumutekano, kwiringirwa, no gukora. NSF - yungurura amazi yemewe nibyiza kumasoko kuko arinda abantu uburozi butandukanye buboneka mumazi ya robine.
Icyo icyemezo cya NSF gisobanura: Ikimenyetso cyizere
NSF International, yahoze yitwa Fondasiyo y’isuku, ni itsinda rya leta ryigenga, ritari - rikora mu rwego rwo kurengera ubuzima n’umutekano rusange. Yashinzwe mu 1944 kandi ishyiraho ibipimo ngenderwaho, igerageza ibintu neza, ikanabaha ibyemezo niba bigira ingaruka kubuzima rusange, nka sisitemu yo gutunganya amazi. Yamenyekanye n’amatsinda yubahwa ku isi, harimo n’umuryango w’ubuzima ku isi (OMS), kubera ko atabogamye kandi afite ubumenyi mu bya siyansi.
Ikirango cya NSF kuyungurura amazi kirenze ikirango gusa; ni ikimenyetso c'ukwizera. Bisobanura ko ibicuruzwa byageragejwe neza kugirango byemeze ko byujuje ibyangombwa byubuzima rusange. Ibi bizamini bigenzura umutekano wibintu kugirango hamenyekane neza ko nta bintu by’ubumara byinjira mu mazi, ubunyangamugayo bw’imiterere kugira ngo harebwe niba sisitemu idasenyuka bitewe n’igitutu, kandi cyane cyane, kugabanya umwanda uvuga ko filtri ikora nkuko ibivuga.
Tekinoroji Yibanze Yibanze muri Sisitemu Yemejwe na NSF
NSF - muyunguruzi yemewe ikoresha gukata - tekinoroji yohanze yagenewe gukuraho umwanda runaka. Icyemezo kirimo ibipimo byinshi, buri kimwe kijyanye nubwoko butandukanye bwo kuyungurura n'ubushobozi bwayo:
- Gukoresha Carbone Filtration (NSF / ANSI 42 & 53): Ubu ni bumwe muburyo bwikoranabuhanga bukunze kugaragara. Mugabanye urugero rwa chlorine mumazi, ibyemezo bya karubone byemewe bituma biryoha kandi bihumura neza. Icy'ingenzi cyane, Standard 53 yerekana ko rwose bakuraho ubuzima - bihumanya bifitanye isano n’isasu, ibinyabuzima bihindagurika (VOC), imiti yica udukoko, nindi miti.
- Sisitemu ya Osmose (RO) Sisitemu (NSF / ANSI 58): Sisitemu ya RO iyungurura byose. Icyemezo ngenderwaho cyerekana ko sisitemu ishobora gukuraho ibintu byinshi byashonga, nka fluoride, nitrate, arsenic, na chromium ya hexavalent. Kugirango bisukure byuzuye, sisitemu mubisanzwe ifite ibyiciro birenze kimwe, nka pre - muyunguruzi, RO membrane, na post - muyunguruzi.
.
Ni ngombwa cyane kubona akayunguruzo gafite icyemezo cya NSF gikenewe. Niba ukuye amazi yawe mumujyi, ugomba kubona sisitemu yapimwe kandi yemerewe kugabanya chlorine, gurş, na VOC (nkiziri munsi yubuziranenge 42/53). Niba amazi afite ibintu byinshi byashonze cyangwa imiti imwe nimwe nikibazo, sisitemu ya RO yemewe irashobora kuba inzira nziza.
Impamvu Icyemezo cya NSF ari ngombwa: Kurenza Kwamamaza
Hano hari amasoko menshi yo kuyungurura isoko atanga amasezerano akomeye. Icyemezo cya NSF kigabanya urusaku ruguha gihamya yundi muntu. Cyakora itandukaniro hagati yibicuruzwa byageragejwe gusa kubipimo bya NSF nibyemejwe kumugaragaro na NSF. Iri tandukaniro ni ingenzi cyane kurinda abakiriya umutekano.
Na none, icyemezo cya NSF cyujuje amategeko ahantu henshi. Kurugero, NSF / ANSI Standard 61 ivuga ko ibice nibikoresho byemewe gukoreshwa muri sisitemu y’amazi yo kunywa. Ibi bifasha ababikora kugera kubyo basabwa kubahiriza. Ku bakiriya, ibi bivuze amahoro yo mumitima kuva bazi ko akayunguruzo bahisemo gashyigikirwa na siyanse kandi kemewe ninzego zubuzima ku isi.
Nigute ushobora kugenzura no gutora iburyo bwa NSF - byemewe
Guhitamo akayunguruzo keza, ugomba kubanza kumenya ubwoko bwamazi ufite. Ikizamini cyamazi nintambwe yambere yambere yo kumenya ubwoko bwanduye buri mumazi. Umaze kumenya icyo ukeneye, shakisha muyunguruzi zemewe gukemura ibyo bibazo.
Buri gihe ugenzure ibyasabwe. Inzira yoroshye nukujya kumurongo kumurongo wemewe wa NSF. Urashobora kugenzura ibipimo byihariye (nka 42, 53, na 58) icyitegererezo cyibicuruzwa byemejwe mugushakisha izina ryuwabikoze. Ibi biremeza neza ko amakuru asobanutse kandi yukuri.
Multi - sisitemu yikoranabuhanga ni amahitamo meza yo kurinda byuzuye. Abahanga benshi bavuga ko gukoresha tekinoroji irenze imwe yo kuyungurura, nka karubone pre - iyungurura hamwe na sisitemu ya RO, nuburyo bwiza bwo guhangana n’ingaruka ziterwa na mikorobi ndetse n’umwanda w’imiti.
Mu gusoza
Icyemezo cya NSF nigikoresho cyingenzi mugushakisha amazi meza. Bituma guhitamo bigoye byungurura amazi byoroshye kuguha imikorere yizewe namakuru yumutekano. Iyo abantu hamwe namasosiyete bahisemo akayunguruzo ka NSF -, ntabwo bagura ibicuruzwa gusa, ahubwo banabigaragaza mubuhanga bwa siyansi - byagaragaye ko barwanya umwanda. Ibi byemeza ko bazabona amazi meza, - uburyohe bwamazi mumyaka iri imbere.
