Ka nts'etsopele ea moruo oa mahaeng le keketseho ea baahi, ho qhalloa ha likhoerekhoere malapeng le hona ho ntse ho eketseha. E le ho sireletsa tikoloho ea mahaeng le bophelo bo botle ba batho, ho hlokahala hore ho hahoe lits'ebeletso tse eketsehileng tsa likhoerekhoere ho hloekisa likhoerekhoere tsa mahaeng. Township likhoerekhoere semela kopantswe thepa e hlahile ka nako ea histori, hore mosebetsi oa eona tshebetso hantle kamoo, kajeno ho utloisisa.
Thepa e kopantsoeng ea setsi sa ho hloekisa likhoerekhoere tsa makeisheneng haholo-holo e sebelisa mokhoa oa AO oa phekolo ea likokoana-hloko ho tlosa litšila tse phelang le ammonia nitrogen. Molao-motheo oa eona oa ho sebetsa o sehlopheng sa A, ka lebaka la bongata bo bongata ba lintho tse phelang metsing a likhoerekhoere, likokoana-hloko li boemong ba hypoxia, ka nako ena, likokoana-hloko ke likokoana-hloko tse sebetsang hantle, li tla senya naetrojene ea manyolo ka likhoerekhoere ho NH?-N, ha u ntse u sebelisa mohloli oa carbon e le mofani oa elektronike, NO?-N, NO?-N e fetoloa ho N? Le ho sebelisa mehloli e meng ea organic carbon le NH?-N bakeng sa ho qaptjoa ha lisebelisoa tse ncha tsa cellular.
Ka hona, sehlopha sa A sa lisebelisoa tsa ho hloekisa likhoerekhoere ha se feela hore se na le ts'ebetso e itseng ea ho tlosa lintho tse phelang, ho fokotsa boima ba tanka ea aerobic e latelang, e loketseng ho nitrification, empa hape e itšetlehile ka bongata bo bongata ba lintho tse phelang tse teng metsi a tala ho tlatsa denitrification, 'me qetellong ho felisa tšilafalo ea naetrojene eutrophic.
Sehlopheng sa O, hobane mahloriso a lintho tse phelang a fokotsehile haholo, empa lisebelisoa tse kopantsoeng tsa likhoerekhoere li ntse li e-na le palo e itseng ea lintho tse phelang le NH?-N e phahameng. E le ho etsa ho senyeha ho eketsehileng ha oxidation ea lintho tse phelang, 'me tlas'a ho phethoa ha carbonization, matla a nitrification a tsoela pele hantle, tanka ea aerobic biological contact oxidation e nang le thepa e tlaase e behoa boemong ba O.
Likokoana-hloko tsa Aerobic le libaktheria tsa "self-oxygenic" li fumaneha haholo sehlopheng sa O-letamo la lisebelisoa tse kopantsoeng tsa likhoerekhoere. Na li-microorganisms tsa aerobic li senya lintho tse phelang ho ba CO? Mme H? O, Inorganic carbon kapa CO moeeng? E le mohloli oa limatlafatsi, na NO ka likhoerekhoere?-N, NO?-N fetoha N?. Metsi a metsi a letamo la O a phallela letamong la A, a fana ka moamoheli oa elektrone bakeng sa letamo la A, 'me qetellong a felisa tšilafalo ea naetrojene ka denitrification.
