Madzi apampopi:Madzi apampopi amatanthauza madzi omwe amapangidwa akatsukidwa ndi kupha tizilombo toyambitsa matenda ndi malo oyeretsera madzi apampopi ndipo amakwaniritsa miyezo yofananira pa moyo wa anthu ndi momwe amapangira.Muyezo wa kuuma kwa madzi apampopi ndi: national standard 450mg/L.
Madzi ofewa:amatanthauza madzi omwe kuuma (makamaka calcium ndi magnesium ayoni m'madzi) kwachotsedwa kapena kuchepetsedwa pang'ono.Panthawi yochepetsera madzi, kuuma kokha kumachepa, koma mchere wonse umakhala wosasinthika.
Madzi opanda mchere:amatanthauza madzi omwe mchere (makamaka ma electrolyte amphamvu osungunuka m'madzi) achotsedwa kapena kuchepetsedwa pang'ono.Madulidwe ake nthawi zambiri amakhala 1.0 ~ 10.0μS/cm, resistivity (25℃) (0.1~1.0)×106Ω˙cm, ndipo mchere ndi 1~5mg/L.
Madzi oyera:amatanthauza madzi omwe ma electrolyte amphamvu ndi ma electrolyte ofooka (monga SiO2, CO2, etc.) amachotsedwa kapena kuchepetsedwa kufika pamlingo wina.Mayendedwe ake amagetsi nthawi zambiri amakhala: 1.0~0.1μS/cm, madutsidwe amagetsi (1.01.0~10.0)×106Ω˙cm.Mchere uli ndi <1mg/L.
Madzi a Ultrapure:amatanthauza madzi omwe conductive sing'anga m'madzi pafupifupi kuchotsedwa kwathunthu, ndipo nthawi yomweyo, non-dissociated mpweya, colloids ndi organic zinthu (kuphatikizapo mabakiteriya, etc.) amachotsedwa pa mlingo otsika kwambiri.Madulidwe ake nthawi zambiri amakhala 0.1 ~ 0.055μS/cm, resistivity (25℃)﹥10×106Ω˙cm, ndi mchere wambiri﹤0.1 mg/L.The (theoretical) conductivity ya madzi abwino abwino ndi 0.05μS/cm, ndipo resistivity (25℃) ndi 18.3×106Ω˙cm.
