Yumbura tacewa don wankewar ruwa

Gidaran yumbura don tsaftace ruwa yana daya daga cikin zabi don tsarkakewa na ruwa a gabanin amfani da abinci da abin sha. Akwai tsarin da yawa na irin wannan tsarin, wanda ya fito daga ƙananan kwamfutar tafi-da-gidanka, yana ƙare tare da manyan mutane, an sanya shi a kan nutse a matsayin mai sarrafawa mai tsada.

Ta yaya yakin yumbu ya yi aiki don tsabtace ruwa?

Tsararren yumbura ne irin tacewa tare da ƙananan nau'in pore da ke sarrafa duka sutura da kwayoyin, ya ba ku cikakken ruwa mai tsabta.

Wani mai sarrafa ruwa tare da kwakwalwar yumbura yana ba da damar ruwa ta hanyar miliyoyin pores a farfajiyar, yayin da ake kiyaye magungunan kwayoyin halitta da gurɓataccen kwayoyin halitta (har zuwa 0.5 microns) a kan gine-gine.

A cikin kwakwalwar zai kasance duk masu gurɓatawa waɗanda suka iya kaiwa ta hanyar waje. Wannan ya tabbatar da cewa a cikin katako akwai matashi mai rikitarwa tare da ƙwanƙwasawa da ƙwanƙwasawa tare da kusassun kusurwa, ta hanyar abin da sauran ƙananan ƙwayoyin ƙwayar dole su wuce. Za su ci gaba da zama a cikin waɗannan tarko masu tarin yawa, kuma a cikin kayan sarrafawa za ku sami ruwa mai tsabta.

Irin waɗannan kwakwalwa za a iya amfani da su a cikin ajiyar ajiya. Bugu da ƙari ga kayan shafa, suna amfani da carbon aiki. Wannan haɗin hanyoyin tsarkakewa yana ba da ruwa, tsabta ta 98%.

Ruwan ruwa tare da membrane mai yumbura yana aiki ta hanyar ruwa da ruwa a karkashin ruwa mai rufi ta hanyar membrane, ya raba shi cikin raguna guda biyu - filtrate da kuma mayar da hankali. A sakamakon haka, dacewa ruwa mai tsabta zai tara a gefe ɗaya na membrane, kuma a gefe ɗaya dukan masu gurɓata zasu kasance.

Ka'idodin aiki na membrane shine jinkirin kananan kwayoyin gurbatawa a cikin kwakwalwan yumburo na membrane, yana da girman daga 0.1 zuwa 0.05 microns. A karkashin matsin ƙwayar, kwayoyin ruwa sun wuce ta wannan minti na minti, wankewa da kowane nau'i na gurbatawa wanda kawai ba zai iya shiga cikin irin wannan ƙananan pores a jikin membrane ba.

Babban mawuyacin ƙarar yumbura ta hanyar tacewa don ruwa shi ne cewa bazai canza ma'ajin gishiri ba, kamar yadda a cikin baya osmosis tsarin. Sauran amfani da yumbu membranes sun hada da:

• juriya ga alkalis da acid;
• high thermal kwanciyar hankali;
• ƙarfin inji;
• juriya ga ƙwayoyin abrasive;
• simplicity of tsabtatawa (ka kawai lokaci-lokaci wanke membrane);
• tsawon rayuwar sabis.
