Imishini yokuhlanza indle ye-MBR ngelinye igama le-membrane bioreactor. Kuyimishini edidiyelwe yokuhlanza indle enobuchwepheshe obuphambili. Kwamanye amaphrojekthi anezidingo eziphezulu zokuchithwa kwamanzi kanye nokulawulwa okuqinile kokungcoliswa kwamanzi, i-membrane bioreactor yenza kahle kakhulu. Namuhla, i-Liding Environmental Protection, umkhiqizi ochwepheshe wezinto zokuhlanza indle, uzokuchazela lo mkhiqizo ngendlela esebenza kahle kakhulu.
Ingxenye eyinhloko yemishini yokuhlanza indle ye-MBR ulwelwesi. I-MBR ihlukaniswe yaba izinhlobo ezintathu: uhlobo lwangaphandle, uhlobo olungaphansi kwamanzi kanye nohlobo oluyinhlanganisela. Ngokuya ngokuthi i-oksijini iyadingeka yini ku-reactor, i-MBR ihlukaniswe ngohlobo lwe-aerobic nohlobo lwe-anaerobic. I-Aerobic MBR inesikhathi esifushane sokuqalisa kanye nomthelela omuhle wokukhipha amanzi, ongahlangabezana nezinga lokuphinda lisetshenziswe amanzi, kodwa ukuphuma kwe-sludge kuphezulu futhi ukusetshenziswa kwamandla kukhulu. I-Anaerobic MBR inokusetshenziswa kwamandla okuphansi, ukukhiqizwa kwe-sludge okuphansi, nokukhiqizwa kwe-biogas, kodwa kuthatha isikhathi eside ukuqalisa, futhi umphumela wokususa ukungcola awulungile njenge-aerobic MBR. Ngokusho kwezinto ezihlukene zolwelwesi, i-MBR ingahlukaniswa ibe yi-microfiltration membrane MBR, i-ultrafiltration membrane MBR njalonjalo. Izinto ze-Membrane ezivame ukusetshenziswa ku-MBR ama-microfiltration membranes kanye ne-ultrafiltration membranes.
Ngokusho kokuxhumana phakathi kwamamojula we-membrane nama-bioreactors, i-MBR ihlukaniswe yaba izinhlobo ezintathu: "i-aeration MBR", "i-separation MBR" kanye "nokukhishwa kwe-MBR".
I-Aerated MBR ibizwa nangokuthi i-Membrane Aerated Bioreactor (MABR). Indlela yokufaka umoya yalobu buchwepheshe iphakeme kuneyendabuko enezimbobo noma microporous big bubble aeration. I-membrane ekwazi ukungena ngegesi isetshenziselwa ukufaka umoya okungenabhamuza ukuze inikeze umoya-mpilo, futhi izinga lokusebenzisa komoyampilo liphezulu. I-biofilm kulwelwesi oluphefumulayo ixhumene ngokugcwele nendle, futhi i-membrane ephefumulayo ihlinzeka nge-oksijini kuma-microorganisms anamathele kuwo, futhi ilulaza ngokuphumelelayo ukungcola emanzini.
Uhlobo lokuhlukanisa i-MBR lubizwa nangokuthi uhlobo lokuhlukanisa okuqinile-uketshezi lwe-MBR. Ihlanganisa ubuchwepheshe bokuhlukanisa ulwelwesi nobuchwepheshe bokwelapha bebhayoloji bomdabu wamanzi angcolile. Ukusebenza kahle kokuhlukanisa okunoketshezi oluqinile. Futhi ngenxa yokuthi okuqukethwe kodaka olucushiwe ethangini lokungenisa umoya kuyenyuka, ukusebenza kahle kokusabela kwamakhemikhali e-biochemical kuyathuthukiswa, futhi ukungcola kwemvelo konakaliswa nakakhulu. Uhlobo lokuhlukanisa i-MBR lusetshenziswa kakhulu kumaphrojekthi we-MBR wokuhlanza indle.
I-Extractive MBR (EMBR) ihlanganisa inqubo yokuhlukanisa ulwelwesi nokugaya kwe-anaerobic. Ulwelwesi olukhethekile lukhipha izinto ezinobuthi emanzini angcolile. Ama-Anaerobic microorganisms aguqula izinto eziphilayo emanzini angcolile zibe i-methane, igesi yamandla, futhi aguqule imisoco (njenge-nitrogen ne-phosphorus) ibe amafomu Amakhemikhali Engeziwe, ngaleyo ndlela akhulise ukutholakala kwezinsiza emanzini angcolile.
