RO (Reverse Osmosis) fasahar reverse osmosis ita ce fasahar rarraba membrane ta amfani da bambancin matsin lamba, wanda ya samo asali ne daga binciken fasahar sararin samaniya ta Amurka a cikin shekarun 1960, a hankali ya canza zuwa farar hula, a halin yanzu ana amfani da shi sosai a fannonin bincike, magani, abinci, abin sha, desalination na ruwa.

RO reverse osmosis membrane aperture karami zuwa nanoscale (1nm = 10)^{-9 (kashi na miliyan mita)}m), a karkashin wani matsin lamba, Kwayoyin H2O na iya wucewa ta hanyar RO membrane, yayin da ƙarancin gishiri, ƙarfe masu nauyi, ƙarfe, colloids, ƙwayoyin cuta, ƙwayoyin cuta da sauransu a cikin ruwan asali ba za su iya wucewa ta hanyar RO membrane ba, don haka za a iya bambanta tsabta tsabta da ruwan da ba za a iya wucewa ba.

General ruwa mai famfo wucewaBayan RO membrane tacewa tsabtace ruwa conductivity zai iya kai 5μs / cm (RO membrane tacewa bayan fitar da ruwa conductivity = shigar da ruwa conductivity x (1-kawar da gishiri rate), gabaɗaya shigo da reverse osmosis membrane kawar da gishiri rate zai iya kai sama da 99%, a cikin shekaru 5 aiki zai iya tabbatar da sama da 97%. Don fitar da ruwa lantarki gudanarwa bukatun mafi girma, za a iya amfani da biyu matakan reverse osmosis, sa'an nan kuma bayan sauki magani, fitar da ruwa lantarki gudanarwa ƙasa da 2μs / cm), dace da dakin gwaje-gwaje uku mataki na ruwa.
