Deality yemvura Dis'on Iyo yakakura-chiyero application yemukana wegungwa wassalination tekinoroji yakatanga muArid Middle East Dunhu, asi haina kungogumira munharaunda iyoyo. Due to over 70% of the world's population residing within 120 kilometers of the ocean, seawater desalination technology has rapidly been applied in many countries and regions outside of the Middle East in the past 20 years.

Asi kwaive kusati kwazana zana ramakore rechi 16 kuti vanhu vakatanga kuita nhamburiko dzekubvisa mvura yakachena kubva kumvura yegungwa. Panguva iyoyo, vaongorori veEurope vaishandisa nzvimbo yemoto pachiteshi kuenda kuchikepe ichibika mvura yegungwa kuti vabudise mvura nyowani panguva yavo yakareba. Kupinza mvura yegungwa kuti ibudise mupfu wemvura, kutonhora uye kudzikisira kuwana mvura yakachena chiitiko chezuva nezuva uye kutanga kwesarudzo yegungwa dema.

Desalination yemaziso azvino yegungwa yakangogadzirwa chete mushure meHondo Yenyika II. Pashure pehondo, nekuda kwekusimudzira kwakasimba kwemafuta neakapetwa nepakati pese kumabvazuva, hupfumi hwedunhu hwakatanga nekukurumidza uye huwandu hwayo huchiwedzera nekukurumidza. Kudiwa kwezvinhu zvitsva zvemvura mune izvi zvakaringana zvinhu zvakaenderera mberi zvichiramba uchiwedzera zuva nezuva. Nzvimbo yakasarudzika yenzvimbo nemamiriro ekunze emidhayedhi eMiddleam

Kubva ma1950s, tekinoroji yegungwa rekusagadzikana yakakurudzira kukura kwayo nekuwedzera kwedambudziko remvura. Pakati peanodarika makumi maviri ematongerwo enyika akagadziridzwa, distylation, electrodidaliasis, uye reverse Osmosis zvese zvakasvikika mwero wekugadzirwa kwemaindasitiri uye anoshandiswa zvakanyanya pasi rese.

Mukutanga kwa1960s, akawanda-nhanho-Stage Flash Equaring Equaring Technology Tekinoroji yemvura yakabuda, uye indasitiri yemazuva ano yegungwa yemazuva ano yakapinda munguva pfupi iri kukudziridza.

Kune anopfuura makumi maviri emvura yegungwa desalination, kusanganisira reverse osmosis, yakaderera mari yekudzvanya, uye sow simba rekushandiswa, Post-kurapwa maitiro akadai se microfiltration, Ultrafiltration, uye Nanefiltration.

Kubva pane yakafara yekubatanidza maonero, inogona kuve yakakamurwa kuita zvikamu zviviri: dismal nzira) uye nzira yemambrane. Pakati pavo, akaderera maitiro ekudzvanya, akawanda-nhanho flash yekubuda, uye reverse osmosis membrane nzira ndiyo nzira huru dzepasi rese. Kazhinji kutaura, kuderera kwakawanda kugona kune zvakanakira kuchengetedza simba, zvinodiwa pakurarama kwemvura yegungwa, uye kunaka kwemvura yakakwirira; Iyo reverse osmosis membrane nzira ine zvakanakira mari yakaderera uye yakaderera simba rekushandisa, asi zvinoda zvinodiwa zvakakwirira zvekutamisa kwegungwa; Iyo yakawanda-nhanho-stage inopenya nzira ine nzira dzakadai sekukura tekinoroji, yakavimbika mashandiro, uye yakakura yekubuda, asi ine simba rakakwirira. Izvo zvinowanzotenda kuti yakaderera yekubudirira discilation uye reverse osmosis membrane nzira nzira dzeramangwana.
