Abstract
The parameters of Fe, Mn, TDS, and TOC contained in groundwater around the coast of Gresik Regency can cause unpleasant odors when exposed to air, yellow stains on clothes, and health problems for people who consume groundwater. The process of aeration and adsorption treatment can be an alternative for reducing the level of pollutants contained in groundwater by utilizing crab shells and duck egg shells as adsorbents. The study was conducted by comparing of 2 processing, the aeration processing process using variations in aeration time of 15 minutes, 30 minutes, and 45 minutes and the adsorption processing process using variations in the type of duck and crab eggshell adsorbents. Adsorption also uses sampling time variations of 20 minutes, 40 minutes, and 60 minutes. In the aeration process, the maximum aeration time for removing Fe, Mn, TDS, and TOC occurs at an aeration time of 45 minutes. The percent allowance for Fe was 91,4%. The percent allowance for Mn was 28,6%. The percentage of TDS allowance was 68,2%. The percentage of TOC allowance is 20,8%. In the adsorption process, the maximum sampling time occurs at 40 minutes. The percent of Fe allowance using duck and crab eggshell adsorbents was 97,8% and 99,2%, Mn by 75,7% and 82,7%, TDS by 84,5% and 94,1%, TOC by 74,6% and 81%. The allowance percent increases as the stirring time increases so the adsorption process can run properly and optimally.
