Biofilter

Biofiltration wata dabara ce ta kula da gurɓata ta amfani da bioreactor wanda ke dauke da kayan rayuwa don kamawa da lalata gurɓataccen abu. Amfani na yau da kullun sun haɗa da sarrafa Ruwa mai guba, kama sunadarai masu cutarwa ko silt daga runoff na ƙasa, da microbiotic oxidation na gurbataccen iska. Za'a iya rarraba biofiltration na masana'antu a matsayin tsari na amfani da oxidation na halitta don cire kwayoyin halitta, ƙanshi, da hydrocarbons.
