Abstract

Landfill generates a problem of soil and water pollution, with leachate wastewater contaminating heavy metals. Wastewater treatment with natural zeolite adsorbents can remove heavy metals from wastewater. We have analyzed the leachate wastewater in the last pond at the wastewater treatment plant at the TPST Piyungan contains lead (Pb) ions of 2.13 mg/L and iron (Fe) of 9.94 mg/L, greater than the
maximum levels allowed for sanitary hygienic water. according to the regulations of the Minister of Health. The concentration of Pb and Fe metal ions in wastewater can be
removed by activated local natural zeolite adsorbents. The adsorbent was prepared from local natural zeolite by activation with ammonium nitrate solution and calcined at 300 oC for 2 hours. Characterization by XRD, BET-adsorption analysis, and SEM showed that activation can increase natural zeolite's surface area and pore size without being
followed by a change in the crystal structure. The leachate adsorption experiment was carried out by varying the weight percentage of activated natural zeolite adsorbent and
adsorption time. The concentration of Pb and Fe ions in wastewater can be reduced by activated natural zeolite adsorbents. Adsorption with 10% weight of natural zeolite and
an adsorption time of 60 minutes delivered the best results. Under these adsorption conditions, the concentration of Pb ions decreased by 38.50% and that of Fe decreased by 67.10%. The adsorption treatment with activated natural zeolite can significantly reduce the concentration of Pb and Fe metal ions in the waste leachate of TPST Piyungan.
