Phetoho ea Membranes ea Metsi a Leoatle la RO

Pale ea li-membrane tsa RO tsa metsi a leoatle e qala ka bo-1960. Bo-rasaense Sidney Loeb le Srinivasa Sourirajan ba ile ba qapa lesela la pele la RO nakong ena. Mosebetsi oa bona o moholo o ile oa betla tsela bakeng sa theknoloji ea ho ntša letsoai, e leng se ileng sa re nolofalletsa ho fetola metsi a leoatle hore e be metsi a hloekileng. Ka ho hlokomelehang, ka 1961, Mopresidente oa United States, John F. Kennedy, o ile a amohela ho ntšoa ha letsoai metsing a leoatle e le morero oa naha, a hlokomela bohlokoa ba hona bakeng sa libaka tse haelloang ke metsi.

Alexander Zarchin, moenjineri oa Isiraele, o thehile ts'ebetso e matla ea ho tlosa letsoai le letsoai lilemong tse fetang 60 tse fetileng. E susumelitsoe ke mofuputsi oa Arctic ea ileng a fumana metsi a nooang leqhoa le qhibilihileng, mosebetsi o mocha oa Zarchin o ile oa betla tsela bakeng sa tsoelo-pele ea theknoloji ea ho ntša letsoai. Mokhoa oa hae o ne o akarelletsa ho hatsetsa metsi a leoatle sebakeng se se nang letho, ho etsa hore leqhoa le ntše letsoai, ebe joale a bokella metsi a hloekileng a tsoang ha a ntse a bokella letsoai. Ho tloha ka nako eo, desalination e 'nile ea tsoela pele ho fetoha, ho fana ka tharollo ea bohlokoa bakeng sa nts'etsopele ea metsi e tsitsitseng lefatšeng ka bophara.

Reverse osmosis ke mokhoa o sebelisoang haholo oa ho ntša letsoai metsing a leoatle. E kenyelletsa ho qobella metsi ka lera le semipermeable le lumellang hore limolek'hule tsa metsi li fete ha li ntse li thibela letsoai le litšila. Metsi a hloekisitsoeng a bokelloa ka lehlakoreng le leng la lera, a siea ka mor'a concentrated brine. RO e hlahisa metsi a hloekileng ho sa tsotelehe hore na letsoai le kae. E ka ba matla haholo 'me e hloka lisebelisoa tsa bohlokoa. Ho feta moo, ho sebetsana le litšila tse chefo tsa brine ke phephetso. Metsi a leoatle le metsi a letsoai haholo. Moea o tsoang moeeng le ho pompa metsi ho ka ja lihora tse ka bang 80 tsa megawate ka megalithara ea metsi a hlahisoang. Linaheng tsa Bochabela bo Hare, hangata limela li sebelisa mocheso o litšila o tsoang lifemeng tsa motlakase tse haufi le oli e theko e tlaase bakeng sa ho ntša letsoai.

Seawater Reverse Osmosis (SWRO) ke mokhoa oa ho ntša letsoai o sebelisang masela a khethehileng ho tlosa letsoai le litšila metsing a leoatle. Li-membrane tsena esale li sebelisoa khoebong ho tloha mathoasong a lilemo tsa bo-1970. Ho fapana le mekhoa ea khale ea ho ntša letsoai e hlokang mocheso kapa liphetoho tsa mekhahlelo, SWRO e itšetleha ka li-membrane, e etsa hore e sebelise matla haholoanyane.

Ka pele ho letsatsi la kajeno, 'me re fumana HID Membrane Co., Ltd. e ka pele ho tlhahiso ea RO membrane. E thehiloe ka 2008, HID e fetohile sebapali se hlahelletseng indastering, ka hare ho China le lefats'e ka bophara.
