Abstract

The robust combination of landfill waste recognized as a potential source of hazards. Landfills is one relatively distinctive issue associated with leachate. Generally, zeolite is considered a known adsorbent however relatively very high in cost. Meanwhile, Feldspar is the world’s most common mineral groups which making up as much as about 60 percent of the crust of the earth. Its quality and availability makes the feldspar become relatively low price material. The mixture of feldspar-zeolite are believe to produces effective and inexpensive composite for the treatment of leachate wastewater. The batch experiment was conducted in an Erlenmeyer flask, 250 mL volume with varying the volume of composite mixture ratio and then shaking for 5 hrs with 200 rpm at pH7. The optimum mixing ratio of feldspar-zeolite is chosen 1:1. The optimum removal of COD and ammonical nitrogen is 55% and 50% respectively. The availability of low-cost materials such as feldspar in the composite has helped to minimize the cost of treatment and has helped to increase the potential capacity for adsorption.
