Mfundo yoyambirira ya mpweya imagwiritsa ntchito ma clorgenic kuti muchepetse mpweya kulowa mu madzi ndikulekanitsa mpweya molingana ndi kutentha kwapadera kwa chinthu chilichonse. Nsanja ya Atatu ya Apprication Amodzi munthawi yomweyo imalandira nitrogen oyera ndi mpweya wabwino pamwamba ndi pansi pa nsanja yapamwamba. Ndikothekanso kutulutsa mpweya wamadzimadzi ndi madzi a nayitrogeni kuchokera kumbali ya Eva poteration ndi mbali ya kumeza kwa kuzizira kwakukulu. Kulekanitsidwa kwa mpweya mu Nsanja yokonzanso kumagawidwa m'magawo awiri, mpweya umalekanitsidwa koyamba mu nsanja ya m'munsi kuti apeze madzi nayitrogeni ndipo nthawi yomweyo amalemeretsa mpweya wamadzi. Mpweya wa oxygen-wolemedwa umatumizidwa ku nsanja yapamwamba kuti mubwezeretse mpweya wabwino ndi nayitrogeni yoyera. Nsanja yapamwamba imagawidwa m'magawo awiri: yokhala ndi malo ophatikizira madziwo monga malire, gawo lapamwamba ndi gawo loyera, ndikuyeretsa gawo la nayitrogeni kuti ichotse chiyero cha mpweya wamadzimadzi.
