| Popis: | Acidic water from the coal mining pool has been polluted from the surrounding coal stockpile stocpile industry. Water quality in mining ponds can threaten the biota in it. During this time, coal mining pool water is widely used for daily needs of the surrounding community such as bathing, washing and even for drinking water. Over time it turns out that coal mine acidic water has been polluted. This problem needs to be sought a solution, one of which is required treatment technology to produce water quality that meets drinking water quality standards. This research tries to use NF270 membrane type Nanofiltration membrane technology to eliminate COD, TSS, TDS, and metal parameters (Fe, Mn). This research was conducted by analyzing the influence of pressure (4, 5, and 6 bar) on the flux and rejection rate of each in each parameter. The results of the study show the processed results as follows; Turbidity, Color, COD, TSS, TDS, Fe and Mn at pressures 4, 5, and 6 bar of acid mine rejection water values, namely; Turbidity (96.23%; 98.7%; 100%), Color (79%; 98%; 100%), COD (57.9%; 63.7%; 83.19%), TSS (73, 3%; 87.2%; 95.8%), TDS (62.7%; 66%; 70.19%), Fe (36%; 74.5%; 100%), Mn (100%; 100 %; 100%). Acidic water treatment in coal mining ponds can be turned into drinking water using nanofiltration membranes producing the best percentage of rejection at pressures of 5 and 6 bar. Water treatment with Nanofiltration membrane technology has produced treated water in accordance with drinking water quality standards required by Minister of Health Decree of the Republic of Indonesia No. 907 / Menkes / Sk / VII / 2002 dan Minister of Environment Decree No. the Decree of the Minister of Environment No. 492 / MENKES / PER / IV / 2010. . |
