Zida zochotsera zimbudzi za MBR ndi dzina lina la membrane bioreactor. Ndi chida chophatikizira chamadzi osamba ndiukadaulo wapamwamba. M'mapulojekiti ena okhala ndi zofunikira zautsi wambiri komanso kuwongolera mwamphamvu zowononga madzi, membrane bioreactor imachita bwino kwambiri. Lero, Liding Environmental Protection, katswiri wopanga zida zochizira zimbudzi, akufotokozereni izi mwaluso kwambiri.
Chigawo chachikulu cha zida zochotsera zimbudzi za MBR ndi nembanemba. MBR imagawidwa m'magulu atatu: mtundu wakunja, mtundu womira komanso mtundu wamagulu. Malingana ndi ngati mpweya ukufunika mu riyakitala, MBR imagawidwa mumtundu wa aerobic ndi mtundu wa anaerobic. Aerobic MBR ili ndi nthawi yochepa yoyambira ndi zotsatira zabwino zotulutsa madzi, zomwe zimatha kukwaniritsa mulingo wogwiritsanso ntchito madzi, koma kutulutsa kwamatope kumakhala kwakukulu komanso kugwiritsa ntchito mphamvu kumakhala kwakukulu. Anaerobic MBR ali otsika mphamvu mowa, otsika sludge kupanga, ndi biogas m'badwo, koma zimatenga nthawi yaitali kuyamba, ndi kuchotsa zotsatira za zoipitsa si zabwino monga aerobic MBR. Malinga ndi zinthu zosiyanasiyana nembanemba, MBR akhoza kugawidwa mu microfiltration nembanemba MBR, ultrafiltration nembanemba MBR ndi zina zotero. Mamembrane omwe amagwiritsidwa ntchito kwambiri mu MBR ndi ma membrane a microfiltration ndi ultrafiltration nembanemba.
Malingana ndi kuyanjana pakati pa ma modules a membrane ndi bioreactors, MBR imagawidwa m'magulu atatu: "aeration MBR", "kupatukana MBR" ndi "m'zigawo za MBR".
Aerated MBR imatchedwanso Membrane Aerated Bioreactor (MABR). Njira yopangira mpweya yaukadauloyi ndi yabwino kuposa momwe zimakhalira porous kapena microporous lalikulu kuwira mpweya. Mpweya wodutsa mpweya umagwiritsidwa ntchito popanga mpweya wopanda thovu kuti upereke okosijeni, ndipo kugwiritsa ntchito mpweya kumakhala kokwera. The biofilm pa nembanemba mpweya ndi kukhudzana kwathunthu ndi zimbudzi, ndi nembanemba mpweya amapereka mpweya kwa tizilombo tating'onoting'ono ophatikizidwa, ndipo efficiently amawononga zoipitsa madzi.
Mtundu wolekanitsa MBR umatchedwanso mtundu wolekanitsa wamadzimadzi olimba MBR. Imaphatikiza ukadaulo wolekanitsa nembanemba ndi ukadaulo wazidziwitso wachilengedwe wamadzi onyansa. Kulekanitsa kolimba kwamadzimadzi. Ndipo chifukwa cha kuchuluka kwa zinyalala mu thanki ya aeration, mphamvu ya biochemical reaction imakhala bwino, ndipo zowononga zachilengedwe zimawonongekanso. Mtundu wolekanitsa wa MBR umagwiritsidwa ntchito kwambiri m'mapulojekiti oyeretsa zimbudzi za MBR.
Extractive MBR (EMBR) imaphatikiza njira yolekanitsa ya nembanemba ndi chimbudzi cha anaerobic. Ma nembanemba osankhidwa amachotsa zinthu zapoizoni m'madzi oipa. Tizilombo tating'onoting'ono ta Anaerobic timasintha zinthu zomwe zili m'madzi onyansa kukhala methane, mpweya wopatsa mphamvu, ndikusintha zakudya (monga nayitrogeni ndi phosphorous) kukhala mitundu Yambiri yamankhwala, potero zimakulitsa kubweza kwa zinthu kuchokera m'madzi onyansa.
