Membrane bioreactor fasaha ce ta kula da ruwa wacce ta haɗu da fasahar membrane da halayen biochemical a cikin maganin najasa. Membrane bioreactor (MBR) yana tace najasa a cikin tankin amsa sinadarai tare da membrane kuma yana raba sludge da ruwa. A gefe guda, membrane yana shiga cikin ƙananan ƙwayoyin cuta a cikin tanki na amsawa, wanda ke ƙara yawan maida hankali na sludge a cikin tanki zuwa babban matakin, ta yadda tasirin biochemical na lalata ruwa ya yi sauri da sauri. A gefe guda kuma, samar da ruwa yana da tsabta kuma a bayyane saboda babban madaidaicin tacewa na membrane.
