Matakan tsarin RO
Tsarin RO na yau da kullun yana da matakan tacewa ɗaya zuwa biyar. Mafi na kowa shine tsarin RO uku, hudu, ko biyar.

Duk tsarin osmosis na baya suna aiki akan ƙa'idodin asali iri ɗaya, waɗanda suka haɗa da tacewa ɗaya ko fiye, matatar carbon, da membrane RO.
Mataki na 1 - Tacewar ruwa
Wannan shine yawanci matakin farko (filter) a cikin tsarin tacewa RO. Matakin ne da gurɓatattun abubuwan da ake iya gani kamar tarkace, tarkace, datti, ƙura, da sauran ɓangarorin ke ware daga ruwan da ke fitowa daga tushen ruwa (misali rijiya ko famfo)
Mataki na 2 / 3 - Pre-carbon filters da RO membrane
Tace carbon da RO membrane suna aiki don cire chlorine, Volatile Organic Compounds (VOCs), da sauran ƙazanta waɗanda zasu iya shafar launi ko warin ruwa. Waɗannan matakan sun haɗa da abubuwan tace carbon da aka riga aka kunna, da RO membrane, da kuma abubuwan tace carbon da aka kunna.
