Zida zosavomerezeka zanyumba (Ecological tank)

Madzi akuda choyamba amalowa mu thanki yomaliza yomaliza ntchito, pomwe scum ndi mawonekedweyi amagwirizanitsidwa, ndipo sumu ndi katswiri amalowa mu gawo lachilengedwe la zida. Imadalira tizilombo tating'onoting'ono m'madzi ndi kama wosuntha pambuyo pa membrane atapachikidwa chithandizo, hydrolysis ndi acidication amanyoza zachilengedwe, kuchepetsa cod, ndikutsatira. Pambuyo mankhwala chithandizo, chimbudzi chimayamba kulowa muyeso wa bondo. Zipangizo zomwe zasankhidwazo zakhala zikulepheretsa Amoni a Ammorgen, kugwirira ntchito zoimitsa, kupha Escher Colin Clion, ndi zida zothandizira, zomwe zimatsimikizira kuchepetsa bwino kwa cod ndi ammonia nayitrogeni. Pamaziko okumana ndi miyezo yothirira, zofunika kwambiri zitha kukwaniritsidwa. Kubisala kumatha kukhala ndi thanki yoyera yopatulira ndikusonkhanitsa madzi a mchira, kukumana ndi zofunikira zogwiritsira ntchito zothandizira zakumidzi.
