Ukuchithwa yinkqubo yokususa ityiwa kunye nezinye izimbiwa kumanzi olwandle ukuyenza ilungele ukusetyenziswa kwabantu okanye ukusetyenziswa kwemizi-mveliso. Oku kwenziwa ngeendlela ezahlukeneyo kubandakanya ukuguqula i-osmosis, ukuhlangana kunye ne-electrodialysis. Ukuchithwa kwamanzi olwandle kukuba ngumthombo obalulekileyo obalulekileyo wamanzi amatsha kwiindawo apho ubutyebi bamanzi amatsha bunqabile okanye bungcolile. Nangona kunjalo, oku kunokuba yinkqubo ebanzi-enamandla, kwaye iBrine egxile ishiywe emva kokuba ichithwe ithathelwe ingqalelo ngononophelo ukuze ingabi nako ukonakalisa indalo esingqongileyo.

I-Yatai Jietong ekhethekileyo yoyilo, ukwenziwa komthamo ohlukeneyo woomatshini bokuchitheka amanzi aselwandle ngaphezulu kwe-20years. Iinjineli zezobugcisa ezinobuchule zinokwenza uyilo ngokwemfuno ethile yomthengi kunye nendawo eyiyo.
