EFFECTIVENESS TEST OF ABSORPTION CAPACITY OF ACTIVATED CHARCOAL BY IMMERSING H3PO4 AND GRAIN SIZE PALM OIL SHELLS ON INSTALLATION OF PEAT WATER TREATMENT

Peat water is one of the ground or surface water found in swampy and lowland peat areas, brownish red, high acidity, and has high organic content. Palm shells activated charcoal can be useful as a raw material for making activated carbon because it is very effective at absorbing organic content in peat water, testing the effectiveness of peat water treatment installation with activated arbons is one way to determine the adsorption power of activated charcoal against peat water contaminants. The aim of this study was to determine the absorption capacity of activated charcoal by immersing H3PO4 and grain size of mesh 200 palm oil shells through the effectiveness test of peat water treatment installation. The variables observed with the effectiveness test of peat water treatment installation were pH and iron content (Fe). Analysis of the data used is descriptive analysis that compares before and after treatment of peat water with activated carbon. From the measurement results of peat water parameters compared with the quality standards of the Regulation of the Minister of Health of the Republic of Indonesia Number 492 of 2010 concerning Drinking Water Quality. The results of testing the effectiveness of peat water installation with activated charcoal as a result of activation by immersion using Phosphoric Acid (H3PO4) with a grain size of palm shell charcoal of 200 mesh can improve the quality of peat water but do not meet clean water quality standards that are fit for drinking. An increase in peat water pH from 4.443 to 6.4 - 6.5, and a decrease in Fe content from 9.43 mg / l to 2.275 - 3.309 mg / l.
