Zipangizo zotsukira zinyalala za MBR ndi dzina lina la membrane bioreactor. Ndi chipangizo choyeretsera madzi a m'nyanja.zida zoyeretsera zinyalala zophatikizikandi ukadaulo wapamwamba. M'mapulojekiti ena omwe ali ndi zofunikira zambiri zotulutsa madzi ochulukirapo komanso kuwongolera kwambiri kuipitsa madzi, membrane bioreactor imagwira ntchito bwino kwambiri. Masiku ano, Liding Environmental Protection, kampani yopanga zida zotsukira zinyalala, ikufotokozerani izi bwino kwambiri.
Gawo lalikulu laZipangizo zoyeretsera zinyalala za MBRndi nembanemba. MBR imagawidwa m'mitundu itatu: mtundu wakunja, mtundu wozama ndi mtundu wa composite. Malinga ndi ngati mpweya ukufunika mu reactor, MBR imagawidwa m'mitundu ya aerobic ndi mtundu wa anaerobic. Aerobic MBR imakhala ndi nthawi yochepa yoyambira komanso zotsatira zabwino zotulutsa madzi, zomwe zimatha kukwaniritsa muyezo wogwiritsanso ntchito madzi, koma kutulutsa kwa matope kumakhala kwakukulu ndipo mphamvu zimagwiritsidwa ntchito kwambiri. Anaerobic MBR imakhala ndi mphamvu zochepa, kupanga matope ochepa, komanso kupanga biogas, koma zimatenga nthawi yayitali kuyambitsa, ndipo zotsatira zochotsa zodetsa sizili bwino ngati aerobic MBR. Malinga ndi zinthu zosiyanasiyana za nembanemba, MBR ikhoza kugawidwa m'mitundu ya microfiltration membrane MBR, ultrafiltration membrane MBR ndi zina zotero. Zipangizo za nembanemba zomwe zimagwiritsidwa ntchito kwambiri mu MBR ndi microfiltration membrane ndi ultrafiltration membranes.
Malinga ndi kuyanjana pakati pa ma module a membrane ndi ma bioreactor, MBR imagawidwa m'mitundu itatu: "aeration MBR", "leparation MBR" ndi "extraction MBR".
MBR yopumira imatchedwanso Membrane Aerated Bioreactor (MABR). Njira yopumira ya ukadaulo uwu ndi yabwino kuposa njira yachikhalidwe yopumira mabowo akuluakulu okhala ndi mabowo kapena ma microporous. Nembanemba yolowa mpweya imagwiritsidwa ntchito popumira mpweya wopanda mabulowo kuti ipereke mpweya, ndipo kuchuluka kwa mpweya wogwiritsidwa ntchito ndi kwakukulu. Biofilm yomwe ili pa nembanemba yopumira imakhudzana kwathunthu ndi zimbudzi, ndipo nembanemba yopumira imapereka mpweya ku tizilombo toyambitsa matenda tomwe timalumikizidwa nayo, ndipo imawononga bwino zinthu zoipitsa m'madzi.
Mtundu wa MBR wolekanitsa umatchedwanso mtundu wa MBR wolekanitsa madzi olimba. Umaphatikiza ukadaulo wolekanitsa nembanemba ndi ukadaulo wachikhalidwe wokonzera madzi otayidwa. Kuchuluka kwa madzi olimba. Ndipo chifukwa chakuti kuchuluka kwa matope oyambitsidwa mu thanki yopatsira mpweya kumawonjezeka, magwiridwe antchito a biochemical reactions amawonjezeka, ndipo zoipitsa zachilengedwe zimachepa kwambiri. Mtundu wa MBR wolekanitsa umagwiritsidwa ntchito kwambiri mu ntchito zotsukira zinyalala za MBR.
Extractive MBR (EMBR) imaphatikiza njira yolekanitsira nembanemba ndi kugaya chakudya mopanda mpweya. Ma nembanemba osankhidwa amatulutsa mankhwala oopsa kuchokera m'madzi otayidwa. Tizilombo toyambitsa matenda topanda mpweya timasintha zinthu zachilengedwe m'madzi otayidwa kukhala methane, mpweya wa mphamvu, ndikusintha michere (monga nayitrogeni ndi phosphorous) kukhala mitundu yambiri ya mankhwala, motero zimathandiza kwambiri kubwezeretsa zinthu kuchokera m'madzi otayidwa.
