Madzi onse akumwa adzathandizidwa ndi gwero lamadzi, lomwe limakhala la nyanja yam'madzi, mtsinje, madzi, kapena nthawi zina ngakhale madzi osokoneza bongo kapena nyengo zokhudzana ndi nyengo. Kuwunikira gwero lamadzi ndiye kumakuthandizani kuti muyembekezere kusintha kwa chithandizo chamankhwala.
Choyamba: Pre-chithandizo pothandizira madzi, otchedwanso kuphatikiza ndi kukweza, tinthu tokhala ndi mapangidwe a tinthu tating'onoting'ono tomwe timagwera pansi.
Gawo Lachiwiri ndi kufesa, pambuyo pa shetmentation plant, madzi omveka bwino adutsa pa zosefera, nthawi zambiri, fyuluta imapangidwa ndi mchenga, miyala, ndi makala) ndi makala. Pofuna kuteteza mafayilo, tiyenera kuwunika kutumphuka, kuyimitsidwa kolimba, kukhala ndi ma alkalinity ndi magawo ena a madzi.
Gawo lachitatu ndi njira yopezera madeti. Izi ndizofunikira kwambiri, madzi atasefedwa, tiyenera kuwonjezera mankhwala osokoneza bongo m'madzi osefera, monga chlorine, chloramine, ndi dongosolo kuti aphe ma parasi, onetsetsani kuti madzi ndi otetezeka kunyumba.
Gawo lachinayi ndikugawidwa, tiyenera kuyeza PH, kusokonekera, kuwuma, kotsalira chlorine, kukhala ndi nkhawa kapena kuwopseza kuti titha kupezeka pagulu nthawi. Mtengo wotsalira wa chlorine uyenera kukhala wopitilira 0,3mg / l mukamapuma ku chomera chamadzi, ndi kupitirira 0,05mg / l kumapeto kwa mawotchi. Turbidity iyenera kuchepera 1ntu, pH yamtundu wa pH ili pakati pa 6.5 ~ 8,5, chitoliro chidzakhala chotsika ngati chipongwe cha pH ndi gawo losavuta 8.5ph.
Komabe pakalipano, ntchito yamadzi oyang'anira madzi ambiri imakhazikitsidwa, yomwe ili ndi zophophonya zambiri za samemeacy, zosokoneza thupi za anthu etc.bo.bo 15 ndi nthawi yeniyeni. Ikuperekanso chidziwitso mwachangu komanso moyenera pakusankha zochita potengera kusintha kwamadzi munthawi yeniyeni. Pomwepo popereka anthu okhala ndi thanzi labwino komanso labwino.
