Ndi chiyani chabwino? Kusefa kwa UF kapena chotsukira madzi chosefera cha ro.
Pakadali pano, pali mitundu iwiri ya zotsukira madzi pamsika, imodzi ndi yotsukira madzi yosefera kwambiri, ndipo inayo ndi yotsukira madzi yobwerera m'mbuyo. Kusiyana kwakukulu pakati pa mitundu iwiri ya zotsukira madzi ndi kusiyana kwa kulondola kwa kusefera. Zotsukira madzi zosefera kwambiri zimagwiritsa ntchito ma nembanemba osefera kwambiri, omwe amatha kukwaniritsa kulondola kwa kusefera kwa ma microns 0.01, ndipo amatha kusefera zonyansa zambiri m'madzi, koma sangathe kusefera madzi a alkali, omwe ndi amadzi amchere. Gawo lalikulu la chotsukira madzi chobwerera m'mbuyo ndi nembanemba ya RO. Kulondola kwa kusefera kwa nembanemba ya RO kumatha kufika 0.0001 μ m, ndipo kwenikweni mamolekyulu amadzi okha ndi omwe angadutse. Chifukwa chake, madzi oyeretsedwa oyambira omwe amapezeka atasefera sapanga sikelo mu ketulo.
Ponena za chisankho ichi, chingasankhidwe malinga ndi khalidwe la madzi a m'dera lanu. Ngati khalidwe la madzi a m'dera lanu ndi labwino ndipo madzi a alkali ndi ochepa, mungasankhe chotsukira madzi cha ultra filtration, chomwe ndi chotsika mtengo komanso chotsika mtengo. Ngati khalidwe la madzi a m'dera lanu ndi loipa ndipo madzi a alkali ndi okwera kwambiri, mungasankhe chotsukira madzi cha reverse osmosis.

Tilinso ndichotulutsira madzi otentha ndi abwinobwino,chotsukira madzi pansi pa sinkikwa chisankho chanu.
