MembraneReactorua ke cov txheej txheem kev kho kab mob lom neeg nrog rau daim nyias nyias kom muab qib siab ntawm cov organic thiab tshem tawm cov khib nyiab. Thaum tsim raws li, cov tshuab no tuaj yeem muab qib siab ntawm kev tshem tawm cov khoom noj. Nyob rau hauv ib qho system MBR, cov membranes submerged nyob rau hauv ib tug aerated biological reactor. Cov daim nyias nyias muaj qhov porosities xws li 0.035 microns mus rau 0.4 microns (nyob ntawm cov chaw tsim khoom), uas yog txiav txim siab ntawm micro thiab ultrafiltration.
Qhov kev pom zoo no tso cai rau cov dej ntws zoo kom tau txais los ntawm daim nyias nyias thiab tshem tawm cov txheej txheem sedimentation thiab filtration feem ntau siv rau kev kho dej khib nyiab. Vim tias qhov kev xav tau ntawm cov sedimentation raug tshem tawm, cov txheej txheem lom neeg tuaj yeem ua haujlwm ntawm qhov sib xyaw cawv ntau dua. Qhov no ua rau txo cov txheej txheem tankage xav tau thiab tso cai rau ntau cov nroj tsuag uas twb muaj lawm los hloov kho yam tsis tau ntxiv cov tso tsheb hlau luam tshiab. Txhawm rau muab qhov zoo tshaj plaws aeration thiab nplawm ib ncig ntawm daim nyias nyias, cov cawv sib xyaw feem ntau yog khaws cia hauv 1.0-1.2% cov khib nyiab ntau, uas yog 4 npaug ntawm cov nroj tsuag.
