This study aims to know the effect of montmorillonite particle, which were granule and gravel of montmorillonite,prepared from the sintering method and its effectiveness in filtration-adsorption process of the nickel-metal in electroplating liquid waste. The granule and gravel of montmorillonite wereprepared by compaction and sintering processes at a temperature of 900oC. The characterization of granule montmorillonite shows the notoriously random micropore material, which the pore surface area was 8.393 m2/g. While the gravel montmorillonite has a pore surface area of 4,381 m2/g. The test was carried out by flowing electroplating waste with the crossflow filtration method and batch adsorption. The most effective decrease in the concentration of nickel-metal occurred in the granules of montmorillonite with a mass ratio of material through filtration and adsorptionwas 2:3. The effectiveness of filtration-adsorption process for removing nickel metal from liquid waste of electropaling was 83.51%.
