MBR izixhobo zokunyanga amanzi amdaka lelinye igama le-membrane bioreactor. Sisixhobo esidibeneyo sokucoca ugutyulo kunye nobuchwepheshe obuphambili. Kwezinye iiprojekthi ezineemfuno eziphezulu zamanzi amdaka kunye nolawulo olungqongqo longcoliseko lwamanzi, i-membrane bioreactor iqhuba kakuhle kakhulu. Namhlanje, uKhuseleko lweNdalo eLiding, umenzi wezixhobo zokucocwa kwamanzi amdaka ochwephesha, uya kukucacisela le mveliso ngobuchule obubalaseleyo.
Inxalenye engundoqo ye-MBR yezixhobo zokunyanga amanzi amdaka yinwebu. I-MBR yahlulwe yaba ziindidi ezintathu: uhlobo lwangaphandle, uhlobo oluntywilisiweyo kunye nodidi oluhlanganisiweyo. Ngokumalunga nokuba ioksijini iyafuneka kwi-reactor, i-MBR yohlulwe ibe luhlobo lwe-aerobic kunye nohlobo lwe-anaerobic. I-Aerobic MBR inexesha elifutshane lokuqalisa kunye nesiphumo esihle sokukhupha amanzi, esinokuhlangabezana nomgangatho wokusetyenziswa kwakhona kwamanzi, kodwa ukukhutshwa kwe-sludge kuphezulu kwaye ukusetyenziswa kwamandla kukhulu. I-Anaerobic MBR inokusetyenziswa kwamandla aphantsi, ukuveliswa kwe-sludge ephantsi, kunye nesizukulwana se-biogas, kodwa kuthatha ixesha elide ukuqalisa, kwaye umphumo wokususwa kwezinto ezingcolileyo awulungile njenge-aerobic MBR. Ngokwezixhobo ezahlukeneyo zemembrane, i-MBR inokwahlulwa ibe yi-microfiltration membrane MBR, i-ultrafiltration membrane MBR njalo njalo. Izinto ze-Membrane ezisetyenziswa ngokuqhelekileyo kwi-MBR zi-microfiltration membranes kunye ne-ultrafiltration membranes.
Ngokutsho kwentsebenziswano phakathi kweemodyuli ze-membrane kunye ne-bioreactors, i-MBR yahlulwe yaba ziindidi ezintathu: "i-aeration MBR", "ukwahlula i-MBR" kunye ne "extraction MBR".
I-Aerated MBR ikwabizwa ngokuba yiMembrane Aerated Bioreactor (MABR). Indlela yokungenisa umoya yobu buchwepheshe yongamile kune-aeration ye-bubble yendabuko okanye i-microporous enkulu. I-membrane ekwazi ukungena kwigesi isetyenziselwa i-bubble-free aeration ukubonelela i-oksijini, kwaye izinga lokusetyenziswa kwe-oksijini liphezulu. I-biofilm kwi-membrane ephefumulayo idibene ngokupheleleyo kunye nogutyulo, kwaye i-membrane ephefumulayo inika i-oksijini kwii-microorganisms ezifakwe kuyo, kwaye iyancipha ngokufanelekileyo ukungcola emanzini.
Uhlobo lokwahlula i-MBR ikwabizwa ngokuba luhlobo lolwahlulo olululwelo oluqinileyo lwe-MBR. Idibanisa iteknoloji yokwahlula inwebu kunye neteknoloji yonyango lwebhayoloji yemveli yamanzi amdaka. Ukusebenza kokwahlula okuqinileyo okuqinileyo. Kwaye ngenxa yokuba umxholo we-sludge esebenzayo kwi-tank ye-aeration iyanda, ukusebenza kakuhle kwe-biochemical reactions kuyaphuculwa, kwaye ungcoliseko lwe-organic luyancipha ngakumbi. Uhlobo lokwahlula i-MBR lusetyenziswa kakhulu kwiiprojekthi zokucoca ugutyulo lwe-MBR.
I-MBR ekhuphayo (EMBR) idibanisa inkqubo yokwahlula inwebu kunye ne-anaerobic digestion. Iinwebu ezikhethiweyo zikhupha iikhompawundi eziyityhefu kumanzi amdaka. IAnaerobic microorganisms ziguqula izinto eziphilayo kumanzi amdaka zibe yimethane, igesi yamandla, kwaye ziguqule izondlo (ezifana nenitrogen nephosphorus) zibe ziintlobo zeekhemikhali ezingakumbi, ngokwenjenjalo zandisa ukufunyanwa kobutyebi kumanzi amdaka.
