Abstract

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 ofPb and Fe metal ions in the waste leachate of TPST Piyungan.
