Kum’mwera kwa chipululu cha Sahara ku Africa, anthu oposa 340 miliyoni alibe madzi abwino akumwa; ku South Asia, ana oposa 2,000 amafa tsiku lililonse ndi matenda obwera ndi madzi monga kutsekula m’mimba. Kumbuyo kwa ziwerengero zochititsa manthazi ndi vuto la madzi abwino lomwe kaŵirikaŵiri limakumana ndi mayiko amene akutukuka kumene.

Chomera cha Reverse osmosis chimawerengedwa kuti ndi imodzi mwazinthu zodalirika zopezera madzi akumwa abwino chifukwa cha kulondola kwake kolekanitsa komanso mphamvu yabwino yopanga madzi. Itha kugwiritsidwa ntchito m'madzi akumwa, mafakitale, ulimi, chithandizo chamadzi onyansa, kutulutsa madzi am'nyanja ndi mafakitale ena.

Xinjieyuan zida zazing'ono zochizira madzi zam'manja zimalimbikitsidwa padziko lonse lapansi, kuphatikiza zida za reverse osmosis ndi ultrafiltration. Zida zopangira madzi zam'manja zimatha kuchotsa bwino zinthu zomwe zaimitsidwa, ma colloids, mabakiteriya, ndi ma macromolecular organic matter m'madzi. Ndizoyenera madera, zipinda zazikulu, nyumba zogona, malo ogona, mahotela, masukulu, mafakitale, madera amigodi, ndi zina zambiri.

Ngakhale kuti Africa ili ndi mitsinje ndi nyanja zambiri monga Mtsinje wa Nile ndi Mtsinje wa Congo, madera ambiri akukumana ndi zovuta ziwiri za kusowa kwa madzi komanso madzi opanda madzi chifukwa cha nyengo yosagwirizana, kukwera kwachangu kwa anthu, kufooka kwa zomangamanga komanso kuwonongeka kwa chilengedwe.

Chifukwa chiyani Africa ikufunika desalination? Chifukwa cha kuchuluka kwa anthu komanso kusowa kwa madzi ku Africa, madera ena (Casablanca, Rabat, Algeria) apanga zomera zochotsa mchere. Ukadaulo wochotsa mchere ukhoza kulimbikitsa chitukuko cha anthu ndi zachuma, ndipo XJY ndiwokonzeka kupereka mayankho ochotsa mchere.

Pa Meyi 20, 2025, zida ziwiri zoyeretsera madzi za 25m³/h zomwe zidapangidwa ndi China XJY zidanyamuka ku Nansha Port ndikutumizidwa ku Phuket, Thailand. Zipangizozi zidzachepetsa kupanikizika kwa madzi abwino pa nthawi yomwe alendo amabwera kuno. Kutumiza kumeneku kukuwonetsanso kuti ukadaulo wa zida zoteteza zachilengedwe ku China wadziwika padziko lonse lapansi ndipo umapereka njira zatsopano zothetsera kugwiritsa ntchito madzi mokhazikika ku Southeast Asia.

Chiyambireni mliriwu, anthu awona kuti thanzi ndi chitetezo cha anthu ndizofunikira kwambiri, zomwe madzi akumwa abwino komanso aukhondo akhala akufunika kwambiri.
