EFEKTIVITAS SAND FILTER DALAM MENINGKATKAN KUALITAS AIR SUMUR MENJADI AIR MINUM MENGGUNAKAN PARAMETER Fe DAN TDS (Effectiveness of Sand Filter to improve quality of well water into drinking water using Fe and TDS parameters)

Abstract

Water is a chemical substance with the chemical formula H2O, a water molecule is composed of two hydrogen atoms covalently bonded to one oxygen atom. Water treatment process can be carried out by means of filtration. One method used is by using Sand Filter. Sand filter in this study combined with reverse osmosis produced water so hopefully fit for use as drinking water. In this research study on "Effectiveness Sand Filter in improving the quality of well water into drinking water using the parameters of Fe and TDS". The well water is pumped past the sand filters and reverse osmosis drinking water samples are then taken by a variable length of filtration ie the 15th minute, 30th minute, 45th minute, 60th minute. Further samples of well water and drinking water assayed Fe and TDS is using gravimetric method and permanganometry. The results of this study obtained TDS water wells is 12.857 ppm. While drinking water during the 15 minutes that 12.857 ppm, time to 30 minutes is 12.142 ppm, while the 45th minute that 11.428 ppm, and a 60th minute that 10.714 ppm. Fe content of the well water is 0.27%. Fe levels for drinking water 15th minute, 30th minute, 45th minute, 60th minute to equal the amount that is 0.27%.
