Qetello ea ts'ebetso ea ho hloekisa likhoerekhoere hangata ke mokhoa oa karohano oa metsi a seretse a tiileng-metsi. Karohano ea metsi a tiileng e bolela mokhoa oa ho tlosa lintho tse tiileng tse emisitsoeng metsing kapa metsing a litšila, ho kenyelletsa le sedimentation, filtration, membrane filtration, filter press, vacuum le centrifuge. Mokhoeng oa seretse o kentsoeng, mekhoa ea ho sefa lera kapa mekhoa ea ho thella hangata e sebelisoa ho fihlela karohano ea metsi a tiileng. Microfiltration, ho hlakisoa, le ho hloekisa bethe e tebileng ho ka sebelisoa ho tsoela pele ho tlosa likaroloana tse nyenyane tse tiileng ka har'a likhoerekhoere.
Har'a mekhoa e tloaelehileng ea karohano ea metsi a tiileng-metsi, litanka tsa sedimentation li nka sebaka se seholo, ho thata ho li hlokomela, ho nka nako e telele, li theko e boima, 'me ha li tšoanelehe bakeng sa lisebelisoa tse kopantsoeng. Mekhoa ea ho hloekisa ea "membrane" hangata e sebelisa li-membrane tsa MBR, tse nkang sebaka se senyenyane 'me li na le liphello tse ntle tsa ho hloekisa. Leha ho le joalo, li-membrane tsa MBR li thata ho li boloka, li na le tšebeliso e phahameng ea matla, 'me li hloka matsete a maholo.
Ka lebaka la mathata a theknoloji e teng ea karohano ea metsi a tiileng, joalo ka sebaka se seholo sa fatše, tšebeliso e matla ea matla, le tlhokomelo e thata, HYHH e hlahisitse mofuta o mocha oa ho arohana ka mokhoa o phahameng le o tlaase oa tšebeliso ea metsi a tiileng-metsi - baktheria screening filtration. tsamaiso. Sesebelisoa sa tlhahlobo ea baktheria se entsoe ho ipapisitse le boiphihlelo bo sebetsang ba lisebelisoa tsa sedimentation tsa biofilm, ho hlola mathata a ts'ebeliso e matla ea matla le tlhokomelo e thata ea li-membrane tsa MBR, le ho bapala ka botlalo melemo ea tšebeliso e tlase ea matla, othomathike e felletseng, le tlhokomelo e bonolo ea lisebelisoa. sesebelisoa sa ho hlahloba baktheria.
Sehlopha sa skrine sa baktheria se entsoe ka li-biofilm tse 'maloa tse iketselitseng tsona. Biofilm e matla e iketsetsang e entsoe ka lisebelisoa tse khethehileng tsa hydrophilic e le thepa ea motheo. Mokhahlelong oa pele oa mokhoa oa ho arohana ha metsi a seretse, o thehoa ka phallo ea hydraulic cross-flow, microbial secretion ea EPS le ho behoa ha tlhaho ha lihlopha tsa likokoana-hloko tsa likokoana-hloko holim'a thepa ea motheo ea micro-net.

Ka nako e ts'oanang, e ka arola ka ho feletseng Sludge Retention Time(SRT) ho tloha Hydraulic Retention Time (HRT), e loketseng ho laola maemo a ts'ebetso.
