 Oxidation 
Oxidation yana rage buƙatun iskar oxygen biochemical na ruwan sharar gida, kuma yana iya rage gubar wasu ƙazanta Ko tarkace, Magani na biyu yana jujjuya mahaɗan kwayoyin halitta zuwa carbon dioxide, ruwa, da biosolids ta hanyar iskar oxygen da rage halayen.  Ana amfani da iskar oxygen da iskar shaka sosai don kashe kwayoyin cuta.

 Biochemical oxidation (jiyya na biyu) 

 Chemical oxidation 
Ana amfani da ingantattun matakai na iskar oxygen don cire wasu gurɓatattun kwayoyin halitta masu dagewa da yawa da suka rage bayan iskar oxygenation na biochemical. . Disinfection by chemical oxidation kills bacteria and microbial pathogens by adding hydroxyl radicals such as ozone, chlorine or hypochlorite to wastewater.
