Kuyamangaza. Manje sesihlunge abafundi abadinga kakhulu ukufunda lesi sihloko. Uma ulapha ngoba amanzi akho #awahlungi, ungase uthole lolu lwazi luwusizo futhi.
Sikanye nabangani bethu kwa-3M (yebo, i-3M, edume ngokusungula amanothi e-Post-it™), sinciphise amanye amaphutha avamile awenziwa abantu baseMalaysia lapho besebenzisa izihlungi zamanzi futhi sikusize uqonde izihlungi zamanzi Izinhlobo ezahlukene zezimakethe ezitholakalayo; kusukela kuzihlungi zamashubhu e-RM60 kuya emishinini ye-RM6,000.
Ungase ufune ukufaka isihlungi samanzi ekhaya lakho ngezizathu eziningi, ezingahlukaniswa kanje:
Ngakho-ke inkinga iwukuthi amanzi alungisiwe empeleni ahlanzekile ngokwanele ukuba aphuzwe ngqo empompini - inkinga ipayipi elivela efektri (futhi mhlawumbe umbhoshongo wamanzi) eliya ekhaya lakho, kanye nepayipi elivela ekhaya lakho eliya empompini. Ngenxa yokuthi amapayipi awakwazi ukugcinwa noma ukushintshwa njalo, avame ukugqwala noma ukuqongelela izinto ezifana ne-moss nesihlabathi eminyakeni edlule. Njengesilinganiso sokubhekisela, ngo-2018, ama-30% amapayipi amanzi aseMalaysia enziwe nge-asbestos cement afakwe eminyakeni engaphezu kwengu-60 eyedlule. Kunjalo nangamapayiphi endlini yakho noma efulethini, futhi ngaphandle kokuthi kwenziwe ukulungiswa okukhulu, angase angaphinde ashintshwa.
Ngokuvamile, ukunambitheka okukhethekile (abanye bathi amakhemikhali) okuthola emanzini ompompi kuvela enanini elincane le-chlorine elisetshenziselwa ukubulala amagciwane nezinye izifo ngesikhathi sokucubungula. Ezinye izinto ezithinta ukunambitheka kungaba amaminerali avela emthonjeni wamanzi, iminonjana yezinto ezivela emapayipini epulasitiki noma ensimbi ekhaya lakho, noma ngisho nendlela amakhemikhali athile emanzini asabela ngayo lapho ephekwa. Uma unesithakazelo, kunezizathu eziningi zokunambitheka okungajwayelekile okuthola emanzini.
Unalokhu engqondweni, uma ufuna ukusebenzisa amanzi ahlanzekile kuphela ukugeza izinto nokugwema amabala ezingutsheni, khona-ke ufuna isihlungi esingasusa izinhlayiya ezincane kanye nenhlabathi. Okungcono kakhulu, lokhu kungaba ukuhlunga amanzi kwesistimu yonke yendlu esikhundleni sesihlungi sohlobo lwesinki sasekhishini. Ngakolunye uhlangothi, uma ufuna amanzi aphephile namnandi namanzi okugeza ukudla, uzofuna izihlungi ezine-activated carbon nezinye izithako noma ama-membrane ahlukile e-pharmaceutical grade ukususa i-chlorine, ukunambitheka, iphunga, kanye namagciwane emanzini.
Izihlungi eziningi zithi ziyasebenza, futhi ezinye zingase zibe nemiphumela yokuhlolwa, izitifiketi, noma okungenani isithombe esibonisa ngaphambi nangemva. Kufanele ubheje imali yakho emiphumeleni yokuhlolwa kanye nesitifiketi, kodwa futhi khumbula ukuthi lezi nazo zinamazinga ahlukene.
Ngaphandle kokuthi uzimisele ukusebenzisa imali ukuqasha ilabhorethri ezimele ukuhlola ikhwalithi yamanzi akho, isibonakaliso sakho esihle kakhulu isitifiketi - futhi ngokuqinisekile ufuna ukuthola esisodwa esivela ku-NSF International, okuyinhlangano ehlola ikhwalithi yomkhiqizo ngokuzimela futhi ithi iyahambisana nezindinganiso zomphakathi Zokuhlanzeka Nokuphepha.
I-NSF International ekhishwe kwikhathalogi yomkhiqizo we-3M inezindinganiso ezahlukene zokuqinisekisa ngokuya ngomsebenzi wesihlungi samanzi, ngakho nansi uhlu oluphelele lokubhekisela kulo.
Izihlungi azilahlwa ngoba kufanele uzishintshe noma uzilungise njalo… futhi kufanele ngempela uzilungise. Ngaphandle kokuthi usebenzisa umpompi onenkomba yokushintsha noma inkampani izokushayela ucingo ukuze ikukhumbuze, iningi lethu lizosebenzisa indlela ethi “uma amanzi ebukeka ehlanzekile, asikho isidingo sokuwashintsha”. Ungase ucabange ukuthi lokhu akuwona umqondo omuhle, kodwa Nkulunkulu wami, impilo yami nokuphefumula kwami; kubi kakhulu kunalokho ocabanga.
Ngenxa yokuthi izihlungi zibamba zonke izinhlobo zemfucuza, zingaba izindawo zokuzalela amabhaktheriya, okwenza amanzi okuphuza angaphephile kakhulu. Uma isihlungi sihlala isikhathi eside kakhulu, ubeka engcupheni amabhaktheriya ekwakheni i-biofilm kusihlungi, okwenza kube lula ngamabhaktheriya amaningi ukunamathela nokukhula abe amakoloni—njengezibungu ze-Zerg ku-StarCraft. Okwenza izinto zibe zimbi kakhulu, ama-biofilm awakwazi ukuhlehliswa futhi adinga umsebenzi omningi (noma ukushintshwa okuphelele) ukuze awasuse. Ucwaningo olwenziwe eDoha luthole ukuthi izihlungi zezinhlayiya ezingagcinwanga kahle empeleni zingonakalisa ikhwalithi yamanzi, nokuthi izinguquko ekucindezelweni kwamanzi zingaletha udoti oqoqiwe, amabhaktheriya, nama-biofilm ohlelweni lwamanzi lwekhaya lakho.
Kungashiwo ukuthi ukugcina isihlungi samanzi sinakekelwa kahle futhi sinakekelwa kahle kuwumqondo omuhle kakhulu, yingakho kufanele uhlole futhi:
Isibonelo, izihlungi eziningi zamanzi ze-3M™ zinomklamo wokushintsha okusheshayo nokuhlanzekile, okuvumela ukushintshwa kalula kwento yesihlungi (kulula njengokushintsha isibani, akukho ladder edingekayo!), ngisho nezindlela ezifana nama-LED kanye nezinkomba zokuphila kwento yesihlungi ukukukhumbuza lapho udinga ukushintsha.
Indaba eyiqiniso—eminyakeni embalwa edlule, ngemva kokuba umndeni womlobi uthole ukuthi amanzi abukeka engcolile kancane (endlini iminyaka engaphezu kwengu-30), banquma ukuthi sekuyisikhathi sokufaka isihlungi se-sediment. Ngeshwa, asikaze sifunde lesi sihloko, ngakho-ke sikhethe kuphela isihloko esithi “kubonakala sengathi singawenza umsebenzi.” umphumela? Umfutho wethu wamanzi uphansi kakhulu ukufinyelela ethangini lamanzi elisizayo, okudinga ukuthengwa kwephampu yamanzi eyengeziwe. Ukuhlanza nokulungisa nakho kuyakhathaza, ngakho kwadingeka sishayele ummeleli wenkonzo, okwakhulisa nezindleko…uma sikhumbula ukushayela ucingo.
Ngandlela thile, ukuthenga isihlungi samanzi kufana nokuthenga imoto—udinga ukwazi ukuthi ufunani, uhlole izinketho ezifanela isabelomali sakho, ulungiselele ukulungiswa njalo, futhi wenziwe ngumkhiqizo odumile. Okungenani ngezihlungi zamanzi, i-3M izoba ngenye yalezo zinhlobo ezingase zihlole wonke amabhokisi akho okuhlola. Futhi zinohlu lwemikhiqizo olucebile, kusukela kuma-countertop ayisisekelo kanye nezihlungi ezingaphansi kwesinki kuya kubasabalalisi bamanzi ashisayo nabandayo abasebenzisa i-UV—ungabuka uhla lwazo oluphelele lwemikhiqizo lapha.
