MBR ndi kuphatikiza ukadaulo wa nembanemba ndi biochemical reaction pakuchiritsa madzi. MBR sefa zimbudzi mu thanki ya biochemical yokhala ndi nembanemba kuti matope ndi madzi asiyane. Kumbali imodzi, nembanemba imakana tizilombo tating'onoting'ono mu thanki, zomwe zimawonjezera kuchuluka kwa zinyalala zomwe zimayendetsedwa mpaka kufika pamlingo waukulu, motero biochemical reaction ya zimbudzi zikuyenda bwino kwambiri komanso bwino. Kumbali ina, kutulutsa kwamadzi kumakhala kowoneka bwino komanso kwapamwamba kwambiri chifukwa cha nembanemba yolondola kwambiri.
Izi zimagwiritsa ntchito zida zosinthidwa za PVDF, zomwe sizingasungunuke kapena kusweka potsuka msana, pomwe zili ndi chiwopsezo chabwino, makina ogwiritsira ntchito, kukana kwamankhwala komanso kukana kuyipitsa. ID & OD ya nembanemba yolimba ya dzenje ndi 1.0mm ndi 2.2mm motsatana, kusefera mwatsatanetsatane ndi 0.1 micron. Masefedwe akunja ndi akunja, omwe ndi madzi aiwisi, omwe amayendetsedwa ndi kukakamiza kosiyanitsidwa, amalowa mu ulusi wopanda pake, pomwe mabakiteriya, ma colloid, zolimba zoyimitsidwa ndi tizilombo tating'onoting'ono ndi zina zimakanidwa mu thanki ya nembanemba.

Kuchiza, kukonzanso ndikugwiritsanso ntchito madzi otayira m'mafakitale.
Chithandizo cha zinyalala leachate.
Kukweza ndi kugwiritsanso ntchito zimbudzi zamatauni.

Pansipa zosefera zimatsimikiziridwa molingana ndi kugwiritsa ntchito kusinthidwa kwa PVDF hollow fiber ultra filtration nembanemba mumitundu yosiyanasiyana yamadzi:

Kukonzekera koyenera kuyenera kutengedwa ngati madzi aiwisi ali ndi zonyansa zambiri ndi tinthu tating'onoting'ono, kapena mafuta ndi mafuta chifukwa cha kuchuluka kwakukulu m'madzi. Defoamer iyenera kuwonjezeredwa pakafunika kuchotsa thovu mu thanki ya membrane, chonde gwiritsani ntchito defoamer ya mowa yomwe sivuta kuyipitsa.
