Oksijene e qhibilihisitsoeng ke tekanyo ea tekanyo ea oksijene ea khase e ka metsing.Metsi a phetseng hantle a ka tšehetsang bophelo a tlameha ho ba le oksijene e qhibilihileng (DO).
Oxygen e qhibilihisitsoeng e kena metsing ka:
monyetla o otlolohileng sepakapakeng.
motsamao o potlakileng ho tsoa meeang, maqhubung, maqhubung kapa moeeng.
fotosynthesis ea bophelo ba limela tsa metsing joalo ka sehlahisoa sa ts'ebetso.
Ho lekanya oksijene e qhibilihisitsoeng metsing le kalafo ho boloka maemo a nepahetseng a DO, ke mesebetsi ea bohlokoa lits'ebetsong tse fapaneng tsa kalafo ea metsi.Le hoja oksijene e qhibilihisitsoeng e hlokahala ho tšehetsa mekhoa ea bophelo le phekolo, e ka boela ea e-ba kotsi, ea baka oxidation e senyang lisebelisoa le ho senya sehlahisoa.Oksijene e qhibilihisitsoeng e ama:
Boleng: Khatiso ea DO e lekanya boleng ba metsi a mohloli.Ntle le DO e lekaneng, metsi a fetoha a litšila ebile a se na bophelo bo botle a ama boleng ba tikoloho, metsi a nooang le lihlahisoa tse ling.
Tumellano ea Taolo: Ho ipapisa le melaoana, metsi a litšila hangata a hloka ho ba le likarolo tse itseng tsa DO pele a ka tšeloa ka har'a molatsoana, letšeng, noka kapa tsela ea metsi.Metsi a phetseng hantle a ka tšehetsang bophelo a tlameha ho ba le oksijene e qhibilihileng.
Taolo ea Ts'ebetso: Maemo a DO a bohlokoa ho laola phekolo ea likokoana-hloko ea metsi a litšila, hammoho le karolo ea biofiltration ea tlhahiso ea metsi a nooang.Lits'ebetsong tse ling tsa indasteri (mohlala, tlhahiso ea matla) DO efe kapa efe e kotsi bakeng sa tlhahiso ea mouoane 'me e tlameha ho tlosoa le ho tsepamisa mohopolo ho tlameha ho laoloa ka thata.
