Chabwino nchiyani? Kusefa kwa UF kapena kusefa kwamadzi kwa ro.
Pakadali pano, pali mitundu iwiri ya oyeretsa madzi pamsika, imodzi ndi yoyeretsa madzi opitilira muyeso, ndipo inayo ndi reverse osmosis water purifier. Kusiyana kwakukulu pakati pa mitundu iwiri ya oyeretsa madzi ndi kusiyana kwa kusefera molondola. Zosefera zamadzi zosefera kwambiri zimagwiritsa ntchito nembanemba zosefera kwambiri, zomwe zimatha kusefera bwino kwambiri ma microns 0.01, ndipo zimatha kusefa zonyansa zambiri m'madzi, koma sangathe kusefa madzi amchere, omwe ndi amchere amchere. Chigawo chapakati cha reverse osmosis madzi oyeretsa ndi RO nembanemba. Kulondola kwa kusefera kwa nembanemba ya RO kumatha kufika 0.0001 μ m, ndipo kwenikweni mamolekyu amadzi okha ndi omwe amatha kudutsa. Chifukwa chake, madzi oyambira oyeretsedwa omwe amapezeka pambuyo pa kusefera satulutsa sikelo mu ketulo.
Ponena za chisankho ichi, chikhoza kuganiziridwa molingana ndi khalidwe lanu lamadzi. Ngati madzi am'deralo ali abwino komanso alkali yam'madzi ndi yochepa, mutha kusankha makina oyeretsera madzi owonjezera, omwe ndi otsika mtengo komanso otsika mtengo. Ngati madzi am'deralo ali otsika komanso alkali yam'madzi ndiyokwera kwambiri, mutha kusankha choyeretsa madzi cha reverse osmosis.

Kusefera kwa UF Sungani mchere wopindulitsa, Palibe madzi otayira.
Chitetezo chachitetezo, Kuteteza chitetezo chamadzi
Kutsekera kwa ana, Kuteteza wiritsani kuuma ndi kutentha kwambiri, Chikumbutso cha kuchepa kwa madzi,

Ntchito yoyeretsa masikelo
Kugwiritsa ntchito mowonjezereka kumafikira maola 10 kung'anima kocheperako kukumbutsa kuyeretsa sikelo
