Nanofiltration membrane (NF) tace kashi
Nanofiltration membranes yawanci cajin membranes ne, tare da caji mara kyau a saman, wanda zai iya tsangwama cations tare da fiye da valences biyu a cikin ruwa kuma suna riƙe da ions monovalent (kamar ions sodium da potassium ions).Saboda haka, nanofiltration membranes suna riƙe da wasu ma'adanai a cikin ruwa.Material kashi.
Daga cikin gurɓataccen ƙarfe na ƙarfe na yau da kullun, arsenic galibi yana wanzuwa a cikin ruwa azaman ions arsenic trivalent da ions arsenic pentavalent;chromium yafi wanzuwa a cikin sigar ions trivalent da hexavalent a yanayi.Don haka membrane na nanofiltration kuma zai iya tace yawancin karafa masu nauyi.Hakanan zai iya cire wani ɓangare na calcium da magnesium, don haka yana da wani tasiri a cikin laushi mai laushi.
A lokaci guda, nanofiltration membranes na iya rage kwayoyin halitta a cikin ruwa da carcinogens irin su trihalomethanes da aka samar a lokacin chlorination da disinfection na ruwan sha.
