Madzi onse akumwa adzatsukidwa kuchokera ku madzi ochokera ku gwero, omwe nthawi zambiri amakhala nyanja yamadzi oyera, mtsinje, chitsime cha madzi, kapena nthawi zina mtsinje ndipo madzi ochokera ku gwero amatha kukhala pachiwopsezo cha kuipitsidwa mwangozi kapena mwadala komanso kusintha kwa nyengo kapena nyengo. Kuyang'anira ubwino wa madzi ochokera ku gwero kumakupatsani mwayi woyembekezera kusintha kwa njira yochizira.
Gawo loyamba: Kukonza madzi oyambira, omwe amatchedwanso kuti Coagulation ndi Flocculation, tinthu tating'onoting'ono tidzaphatikizidwa ndi mankhwala kuti tipange tinthu tating'onoting'ono, kenako tinthu tating'onoting'ono tidzamira pansi.
Gawo lachiwiri ndi kusefa, madzi oyera akatha kusungunuka m'madzi asanakonzedwe, amadutsa m'mafyuluta, nthawi zambiri fyulutayo imakhala ndi mchenga, miyala, ndi makala) ndi kukula kwa ming'alu. Kuti titeteze mafyuluta, tifunika kuyang'anira kutayikira kwa madzi, madzi olimba omwe ali m'madzi, alkalinity ndi zina zomwe zili m'madzi.
Gawo lachitatu ndi njira yophera tizilombo toyambitsa matenda. Gawoli ndi lofunika kwambiri, madzi akasefedwa, tiyenera kuwonjezera mankhwala ophera tizilombo m'madzi osefedwa, monga chlorine, chloramine, kuti tiphe tizilombo totsala, mabakiteriya, ndi mavairasi, komanso kuti madzi akhale otetezeka akamapita kunyumba.
Gawo lachinayi ndi kugawa, tiyenera kuyeza pH, kukhuthala, kuuma, chlorine yotsalira, conductivity (TDS), kenako tikhoza kudziwa zoopsa zomwe zingachitike kapena zomwe zingawopseze thanzi la anthu panthawi yake. Mtengo wotsalira wa chlorine uyenera kupitirira 0.3mg/L ukatulutsidwa m'madzi akumwa, komanso kupitirira 0.05mg/L kumapeto kwa netiweki ya mapaipi. Kukhuthala kuyenera kukhala kochepa 1NTU, pH ili pakati pa 6.5~8,5, chitoliro chidzakhala chowononga ngati pH ili yochepa 6.5pH ndipo chidzakhala chosavuta kuchiyeza ngati pH ili pamwamba pa 8.5pH.
Komabe pakadali pano, ntchito yowunikira ubwino wa madzi imagwiritsa ntchito kuyang'anira pamanja m'maiko ambiri, komwe kuli ndi zofooka zambiri monga mwachangu, zonse, kupitiriza ndi zolakwa za anthu ndi zina zotero. Dongosolo lowunikira ubwino wa madzi la BOQU pa intaneti limatha kuyang'anira ubwino wa madzi maola 24 komanso nthawi yeniyeni. Limaperekanso chidziwitso mwachangu komanso cholondola kwa opanga zisankho kutengera kusintha kwa ubwino wa madzi nthawi yeniyeni. Potero limapatsa anthu madzi abwino komanso otetezeka.
