Ukukhipha usawoti emanzini kuyinqubo yokukhipha usawoti kanye namanye amaminerali emanzini olwandle ukuze afanelekele ukusetshenziswa abantu noma ukusetshenziswa ezimbonini. Lokhu kwenziwa ngezindlela ezahlukene ezihlanganisa i-reverse osmosis, i-distillation kanye ne-electrodialysis. Ukukhishwa kukasawoti emanzini olwandle kuba umthombo obalulekile wamanzi ahlanzekile ezindaweni lapho imithombo yamanzi ahlanzekile evamile iyindlala noma ingcoliswe khona. Kodwa-ke, lokhu kungaba inqubo edinga amandla amaningi, futhi amanzi ahlanzekile aqinile asele ngemva kokukhishwa kukasawoti emanzini kufanele asingathwe ngokucophelela ukuze angalimazi imvelo.

I-YANTAI JIETONG ikhethekile ekwakhiweni, ekhiqiza umthamo ohlukahlukene wemishini yokukhipha usawoti emanzini olwandle isikhathi esingaphezu kweminyaka engama-20. Onjiniyela bezobuchwepheshe abangochwepheshe bangenza ukuklama ngokwezidingo eziqondile zekhasimende kanye nesimo sangempela sesayithi.
