Abstract
The objectives of this research were to investigate of efficiency of wastewater treatment from air dried rubber
sheet production process by natural adsorbents. The results show that the adsorption efficiencies of nitrogen and
sulfide were different. The natural zeolite was applied to remove nitrogen and sulfide from wastewater. The
optimum flow rate was 300 ml/min; the removal efficiency was 80.80% and 77.95% for Nitrogen and Sulfide,
respectively. And the results show that the effective removal 85.56% and 72.43% at adsorption time was 50
minutes and three times for adsorption by natural zeolite. Accordingly, the adsorbed zeolite can be fertilization in
plants.
Keywords: Air dried Rubber Sheet, Wastewater, Natural zeolite, Adsorption.
