PEMBUATAN AQUADEMINERALIZED DARI AIR SUMUR DAERAH TEMBALANG DAN AIR SUMUR DAERAH UNGARAN MENGGUNAKAN DEMINERALIZER (Produce Aquademineralized from Tembalang’s Well Water and Ungaran’s Well Water By Using Demineralizer)

Abstract

Aqua DM (demineralisation) is water without mineral, aqua DM mineral water which contains ion and through some resin so mineral can be endured in resin coloum. Destination of this experiment is use well water to be aqua demineralisation. Method to make aqua DM is through the water in kation coloum, anion coloum dan mix coloum, to check demineralizer with hardness. Tembalang’s Well water and Ungaran’s well water will be check in 0, 10, 20, 30, 40 and 50 minute with added indicator EBT and will be tritation with EDTA, the color will bw changed from purple to blue with sampel 3,8 ml, 2,6 ml, 2,2 ml, 1,3 ml, 0,8 ml and 0,5 ml and gets hardness 1900 ppm, 1300 ppm, 1100 ppm, 650 ppm, 350 ppm, and 250 ppm. Ungaran’s well sampel is 2,1 ml, 1,8 ml, 1,5 ml, 0,8 ml, 0,6 ml and 0,4 ml and get hardness 1050 ppm, 900 ppm, 750 ppm, 400 ppm, 300 ppm, and 200 ppm. The conclusion is Ungaran’s well water and Tembalang’s well water is not appropriated with aqua demineralitaion Kata kunci : aqua DM (aquademineralized), hardness, demineralized water
