Ingabe bewazi, ukuthi amanzi enza kufika ku-75% wesisindo somzimba womuntu.Ukulahlekelwa ngamaphesenti angu-4 kuphela amanzi aphelele emzimbeni kuholela ekuphelelweni kwamanzi emzimbeni, futhi ukulahlekelwa ngamaphesenti angu-15 kungabulala.Ngokunjalo, umuntu angaphila inyanga engadlile kodwa angeke aphile izinsuku ezi-3 ngaphandle kwamanzi.Lokhu kuncika okubalulekile emanzini kulawula kabanzi zonke izinhlobo zempilo.Ngokusobala, amanzi abalulekile ukuze umuntu aphile, kodwa yini eyenza adingeke kangaka?
Ayikho enye i-molecule efana namanzi uma kuziwa ezintweni eziyingqayizivele ezisekela ukuphila.Ngokujabulisayo, abacwaningi bayaqhubeka nokusungula izindlela ezintsha zokuhlanza amanzi kuye ngokuthi izinga lamanzi ahlanzwayo linjani, izindleko zenqubo yokuhlanza, kanye nezindinganiso zekhwalithi ezilindelekile emanzini asetshenziwe.
Umgomo uwukukhiqiza amanzi alingana nezinjongo ezithile.Amanzi amaningi ayahlanzwa futhi abulawe amagciwane ukuze asetshenziswe abantu (amanzi okuphuza), kodwa ukuhlanzwa kwamanzi kungase kwenziwe ngezinye izinjongo ezihlukahlukene, ezihlanganisa izinhlelo zokusebenza zezokwelapha, ezekhemisi, zamakhemikhali nezezimboni.Kuyamangaza ukuthi i-molecule elula ibaluleke kangakanani emhlabeni wonke ezintweni ezinezidingo ezihlukahlukene.
Ukuhlolwa kokuqala kokuhlunga kwamanzi kuhlehlela emuva ekhulwini le-17.USir Francis Bacon uzame ukukhipha usawoti emanzini olwandle edlula ukugeleza ngesisefo sesihlabathi.Nakuba ukuhlola kwakhe kungazange kuphumelele, kwaphawula ukuqala kwesithakazelo esisha kulo mkhakha.Obaba be-microscope, u-Antonie van Leeuwenhoek noRobert Hooke, basebenzisa isibonakhulu esasisanda kusungulwa ukuze babone okokuqala ngqa izinhlayiya ezincane ezibonakalayo ezilenga emanzini, babeka isisekelo sokuqonda ikusasa lamagciwane atholakala emanzini.
Namuhla abacwaningi basaqhubeka nokufeza izindlela futhi ngobuchwepheshe besimanje, ukuhlanzwa kwamanzi kuye kwathuthuka ngendlela emangalisayo.Ezinye izindlela zokuhlanza amanzi njengokuthi, Izihlungi ze-Membrane manje sezisetshenziswa kabanzi ukuhlunga kokubili amanzi okuphuza, ekusetshenzisweni kwezohwebo nezimboni.Ngamanzi okuphuza, izihlungi zolwelwesi zingasusa cishe zonke izinhlayiya ezinkulu kuno-0.2 μm--okuhlanganisa i-giardia ne-cryptosporidium.Izihlungi zama-membrane ziyindlela ephumelela kakhulu yokwelapha okuphakeme lapho kufiswa ukuphinda kusetshenziswe amanzi embonini, ngezinjongo ezilinganiselwe zasekhaya, noma ngaphambi kokuchithela amanzi emfuleni osetshenziswa amadolobha asondele ezansi nomfula.Zisetshenziswa kakhulu embonini, ikakhulukazi ukulungisa isiphuzo (okuhlanganisa namanzi asemabhodleleni).I-Infect, reverse osmosis membrane systems ingenye yezindlela ezisetshenziswa kakhulu namuhla.
I-Reverse osmosis ingasusa izinhlobo eziningi zamakhemikhali ancibilikisiwe nezimisiwe kanye nalawo ebhayoloji (ikakhulukazi amagciwane) emanzini, futhi isetshenziswa kuzo zombili izinqubo zezimboni nokukhiqizwa kwamanzi aphuzwayo.Silandele lapho sisendleleni, njengoba sabelana ngolwazi oluvela kubaphenyi abangochwepheshe be-HID mayelana nolwelwesi lwe-osmosis oluhlehlayo kanye nokukhiqizwa kwesistimu.Wamukelekile ngemibuzo futhi ikuvumela ukuthi wabelane ngolwazi lwakho ku-ajenda, ukusiza umphakathi wokuhlanza amanzi uthole ulwazi olubanzi o ukuthola amanzi angcono kakhulu, aphephile, nasezingeni.
Ngaphandle kokuqonda okuphelele kwenani lamanzi langempela, elibanzi, ngeke sikwazi ukuvikela lo mthombo obalulekile ukuze kuzuze wonke umuntu.
