Kodi mumadziwa, kuti madzi amapanga 75% ya kulemera kwa thupi la munthu. Kutayika kwa 4% yokha ya madzi onse amthupi kumabweretsa kutaya madzi m'thupi, ndipo kutaya 15% kumatha kufa. Momwemonso, munthu amatha kukhala ndi moyo kwa mwezi umodzi popanda chakudya koma sangakhale ndi moyo masiku atatu popanda madzi. Kudalira madzi kumeneku kumalamulira kwambiri zamoyo zonse. Mwachionekere, madzi ndi ofunikira kuti munthu akhale ndi moyo, koma kodi nchiyani chimene chimawapangitsa kukhala ofunikira chotero?
Palibe molekyu ina imene imafanana ndi madzi pankhani ya zinthu zapadera zimene zimathandizira zamoyo. Chochititsa chidwi n'chakuti, ofufuza akupitiriza kukhazikitsa njira zatsopano zoyeretsera madzi malinga ndi ubwino wa madzi omwe akuyeretsedwa, mtengo wa mankhwala opangira mankhwala, komanso miyezo yapamwamba yomwe ikuyembekezeka pamadzi okonzedwa.
Cholinga chake ndi kupanga madzi oyenera pazifukwa zinazake. Madzi ambiri amayeretsedwa ndi kupha tizilombo toyambitsa matenda kuti anthu amwe (madzi akumwa), koma kuyeretsa madzi kungathenso kuchitidwa pazifukwa zina zosiyanasiyana, kuphatikizapo mankhwala, mankhwala, mankhwala, ndi mafakitale. Ndizodabwitsa kuti molekyu wosavuta ndi wofunikira padziko lonse lapansi kwa zamoyo zomwe zili ndi zosowa zosiyanasiyana.
Zoyeserera zoyamba pakusefera kwamadzi zidayamba m'zaka za zana la 17. Sir Francis Bacon anayesa kuchotsa mchere m’madzi a m’nyanja podutsa m’sefa ya mchenga. Ngakhale kuti kuyesa kwake sikunapambane, kunali chiyambi cha chidwi chatsopano m'munda. Makolo a maikolosikopu, Antonie van Leeuwenhoek ndi Robert Hooke, anagwiritsa ntchito maikulosikopu omwe angopangidwa kumene kuti aone kwa nthawi yoyamba tinthu tating'ono tating'ono tomwe titayirira m'madzi, kuyala maziko oti amvetsetse mtsogolo za tizilombo toyambitsa matenda tomwe timayenda m'madzi.
Masiku ano ochita kafukufuku akupitiriza kukonza njirazo komanso ndi matekinoloje amakono, kuyeretsa madzi kwasintha modabwitsa. Njira zina zoyeretsera madzi monga, Zosefera za Membrane tsopano zimagwiritsidwa ntchito kwambiri kusefa madzi akumwa, muzamalonda ndi mafakitale. Pamadzi akumwa, zosefera za membrane zimatha kuchotsa pafupifupi tinthu tokulirapo kuposa 0.2 μm - kuphatikiza giardia ndi cryptosporidium. Zosefera za mamembrane ndi njira yabwino kwambiri yochizira ku maphunziro apamwamba ngati akufuna kugwiritsa ntchitonso madzi m'makampani, pazifukwa zochepa zapakhomo, kapena asanatulutse madzi mumtsinje womwe umagwiritsidwa ntchito ndi matauni akumunsi kwa mtsinje. Amagwiritsidwa ntchito kwambiri m'makampani, makamaka pokonzekera zakumwa (kuphatikiza madzi am'mabotolo). Infect, reverse osmosis membrane systems ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri masiku ano.
Reverse osmosis imatha kuchotsa mitundu yambiri yamankhwala osungunuka ndi kuyimitsidwa komanso zachilengedwe (makamaka mabakiteriya) m'madzi, ndipo amagwiritsidwa ntchito m'mafakitale komanso kupanga madzi amchere. Titsatireni panjira, pamene tikugawana nzeru kuchokera kwa akatswiri ofufuza a HID pa reverse osmosis membrane ndi kupanga dongosolo. Ndinu olandiridwa ndi mafunso komanso kukulolani kuti mugawane zomwe mukudziwa pazantchito, kuthandiza anthu oyeretsa madzi kuti adziwe zambiri o kupeza madzi abwino kwambiri, otetezeka, komanso abwino.
Popanda kumvetsetsa bwino za mtengo weniweni wa madzi, sitingathe kuteteza gwero lofunikali kuti aliyense apindule.
