Sangano reWorld Health Organization rinoti vanhu vanopfuura mamiriyoni 785 havana pombi yakachena yemvura yekunwa.Kunyange zvazvo chikamu che71% chepasi chakafukidzwa nemvura yegungwa, hatigoni kunwa mvura yacho.
Masayendisiti pasi rose anga achishanda nesimba kuti awane nzira inoshanda yekubvisa munyu mumvura yegungwa zvakachipa.Iye zvino, boka revasayendisiti vekuSouth Korea vangave vakawana nzira yekuchenesa mvura yegungwa mumaminitsi mashoma.
Mvura yakachena inodiwa pamabasa evanhu inongotora 2.5% yehuwandu hwemvura inowanikwa pasi pano.Kuchinja kwemamiriro ekunze kwakakonzera shanduko yekunaya kwemvura nekuoma kwenzizi, izvo zvaita kuti nyika dzizivise kushomeka kwemvura kekutanga munhoroondo yadzo.Hazvishamisi kuti desalination ndiyo nzira iri nyore yekugadzirisa dambudziko iri.Asi maitiro aya ane zvaanogumira.
Paunenge uchishandisa membrane kusefa mvura yegungwa, membrane inofanira kugara yakaoma kwenguva yakareba.Kana iyo membrane ikava yakanyorova, iyo yekusefa ichave isingashande uye inobvumira yakawanda yakawanda yemunyu kuti ipfuure nemu membrane.Kwekushanda kwenguva refu, kunyorova zvishoma nezvishoma kwe membrane kunowanzoonekwa, iyo inogona kugadziriswa nekutsiva membrane.

Iyo hydrophobicity ye membrane inobatsira nekuti magadzirirwo ayo haabvumiri mamorekuru emvura kupfuura.
Pane kudaro, mutsauko wekushisa unoshandiswa kumativi maviri efirimu kuti abudise mvura kubva kune imwe mugumo kuenda kumhute yemvura.Iyi membrane inobvumira mhute yemvura kuti ipfuure uye yobva yabatana kuenda kudivi rinotonhorera.Inonzi membrane distillation, iyi inowanzoshandiswa membrane desalination nzira.Sezvo zvidimbu zvemunyu zvisingashandurwi kuva gaseous state, zvinosara kune rumwe rutivi rwe membrane, zvichipa mvura yakakwirira-yakachena kune rumwe rutivi.
Vatsvagiri vekuSouth Korea vakashandisawo silica airgel mune yavo membrane yekugadzira maitiro, ayo anowedzera kuwedzera kuyerera kwemhute yemvura kuburikidza ne membrane, zvichikonzera kuwana nekukurumidza kumvura yakasvibiswa.Chikwata chakaedza tekinoroji yavo kwemazuva makumi matatu akateedzana ndokuona kuti membrane inogona kuramba ichisefa 99.9% yemunyu.
