PEMBUATAN AIR ACCUMULATOR DAN PENDINGIN KONDENSOR DENGAN MENURUNKAN KESADAHAN AIR BAKU MENGGUNAKAN ION EXCHANGE

High amount of hardness and minerals on the raw water will determine the right technology that could be used for reducing the amount hardness and minerals from it. In this research, multi-bed ion exchange reactor with continue proccess will be used for determining the highest percent removal that could be reach and the best volume of resins that could be used for reducing the amount of hardness and minerals from raw water. Independent variable that will be used in this research is the volume of resins (1L, 2L, 3L, 4L, and 5L) and sampling time (1, 2, 3, 4, and 5 hours). Based on the analysis results, we know that volume resin influence the amount of percent removal that could be reach, but not for the sampling time. The best volume resin that could be used for removing cation is 4L with the average removal of cation reach 86,364% and the best volume resin that could be used for removing anion is 2L with the average removal of anion reach 49,7333%. Cation exchanger that have been used in this research would be exhausted after 3 hours. So, it have to be regenerated every 3 hours. Anion exchanger that have been used for this research would be exhausted after 2 hours. So, it have to be regenerated every 2 hours
