Umbutho wezeMpilo weHlabathi uqikelela ukuba abantu abangaphezu kwezigidi ezingama-785 baswele umthombo ococekileyo wamanzi okusela. Nangona i-71% yomhlaba igqunywe ngamanzi olwandle, asinakukwazi ukusela amanzi.
Izazinzulu kwihlabathi jikelele ziye zasebenza nzima ukufumana indlela esebenzayo yokuphelisa amanzi olwandle ngexabiso eliphantsi. Ngoku, iqela lenzululwazi yaseMzantsi Korea yase-Korea baseSouth Erean isenokuba yafumana indlela yokucoca amanzi aselwandle ngemizuzu emizuzu.
Amanzi amatsha afunekayo kwimisebenzi yabantu aphendula kuphela iiakhawunti ze-2.5% zezixhobo zamanzi ezifumanekayo emhlabeni. Changing climatic conditions have led to changes in precipitation and drying up of rivers, prompting countries to declare water shortages for the first time in their history. Akumangalisi ukuba ukuchithwa yeyona ndlela ilula yokusombulula le ngxaki. Kodwa ezi nkqubo zineentsilelo zazo.
Xa usebenzisa i-membrane ukucoca amanzi olwandle, i-membrane kufuneka igcinwe yome ixesha elide. Ukuba i-membrane iba manzi, inkqubo yoyilo iya kuba ingasebenzi kwaye ivumele inani elikhulu letyuwa lidlule kwi-membrane. Ngomsebenzi wexesha elide, ukumiswa kancinci kwe-membrane kuhlala kujongwa, nto leyo inokusonjululwa ngokutshintsha i-membrane.

I-hydrophobizety ye-membrane iluncedo kuba uyilo lwayo lungavumeli iimolekyuli zamanzi ezidlulayo.
Endaweni yoko, umahluko wobushushu usetyenziswa kumacala amabini efilimu yokuphuma amanzi ukusuka kwelinye icala kumphunga wamanzi. Le membrane ivumela umphunga wamanzi ukuba udlule kwaye emva koko uvele kwicala elipholileyo. Ibize i-membrane distition, le yindlela eqhelekileyo ye-membrane. Kuba amasuntswana etyiwa aguqulwanga kwi-Gaseous State, asala kwelinye icala le-membrane, ebonelela ngamanzi aphezulu okucoceka kwelinye icala.
Abaphandi baseSouth Korea bakwasebenzisa i-Asica Airgeli ye-Airge lenkqubo yabo ye-memnene yemveliso ye-membrane, eyenza ngakumbi ukuphucula indawo yokuhamba kwamanzi nge-membrane, kukhokelela ekufikeleleni ngokukhawuleza kwamanzi. Iqela lavavanya itekhnoloji yabo kwiintsuku ezingama-30 ngokulandelelana kwaye yafumanisa ukuba i-membrane inokuqhubeka nokucoca i-99.9% yetyuwa.
