reduce iron and manganese levels in dug well water has been carried out. This study aims
to make comparisons from two methods to reduce iron and manganese in dug well water.
The parameters optimized in this study are the aeration time and the variation of the addition
of the adsorbent mass and the adsorption time. Based on the research results, the spray
aeration time for 2 hours gave the optimal percentage reduction for Fe 3+ and Mn 4+ metal …
