Ukadaulo wothira madzi m'mafakitale ukhoza kugawidwa m'magulu atatu kutengera zolinga zamankhwala ndi mtundu wamadzi: thupi, mankhwala, ndi zachilengedwe. Amagwiritsidwa ntchito kwambiri pochiza mitundu yosiyanasiyana yamadzi otayira m'mafakitale.
1. Ukadaulo waukadaulo waukadaulo: makamaka kuphatikiza kusefera, mpweya, kuyandama kwa mpweya, ndiukadaulo wolekanitsa wa membrane. Kusefa kumagwiritsidwa ntchito pochotsa tinthu tating'onoting'ono m'madzi; Njira zopangira matope ndi mpweya woyandama zimagwiritsidwa ntchito kulekanitsa mafuta ndi tinthu tating'onoting'ono; Ukadaulo wolekanitsa ma membrane, monga ultrafiltration ndi reverse osmosis, amagwiritsidwa ntchito poyeretsa mwatsatanetsatane ndipo ndi oyenera kuthira madzi otayira amchere ambiri ndikubwezeretsanso zinthu zothandiza.
2. Ukadaulo wamankhwala opangira mankhwala: Kuchotsa zowononga pogwiritsa ntchito mankhwala, kuphatikiza njira monga flocculation, oxidation-reduction, disinfection, and neutralization. Flocculation ndi coagulation amagwiritsidwa ntchito pochotsa tinthu tating'onoting'ono; Njira yochepetsera makutidwe ndi okosijeni ingagwiritsidwe ntchito kuwononga zowononga zachilengedwe kapena kuchotsa zitsulo zolemera; Njira zophera tizilombo toyambitsa matenda monga chlorination kapena mankhwala a ozoni zimagwiritsidwa ntchito kwambiri pogwiritsira ntchito madzi am'mafakitale kapena kuchiza asanatulutsidwe.
3. Ukadaulo wamankhwala achilengedwe: kudalira tizilombo toyambitsa matenda kuti tinyoze zinthu zachilengedwe m'madzi, matekinoloje wamba amaphatikiza njira ya sludge ndi njira yamankhwala a anaerobic. The adamulowetsa sludge ndondomeko ndi oyenera kuchitira madzi oipa ndi mkulu organic katundu, pamene anaerobic mankhwala luso ambiri ntchito pochiza mkulu ndende organic madzi otayira, amene angathe kuwononga bwino zoipitsa ndi kuchira mphamvu (monga biogas).
Ukadaulo uwu umagwiritsidwa ntchito kwambiri pochiza madzi oyipa m'mafakitale monga mafuta, mankhwala, kukonza chakudya, ndi mankhwala. Iwo osati mogwira kuchepetsa kuipitsidwa kwa madzi, komanso kusintha mlingo wogwiritsanso ntchito madzi, kulimbikitsa chitukuko zisathe za kupanga mafakitale.
