- The objective of this research was to produce safe water for shrimp by using zeolite as adsorbent to absorb unwanted substances (NH3 and H2S). In particular, this study also aimed to design the shrimp pond water treatment equipment, effect of flow rate on zeolite ability to absorb toxic gases (NH3 and H2S), and rate of absorption (K) and reaction (k). The adsorbent is zeolite which has adsorption properties, high surface area and pores suitable for water (3Å). Then, the concentration of ammonia, hydrogen sulfide was analyzed using Ammonia Test Kit and Hydrogen Sulphide of Hach Hydrogen Sulfide Test Kit. The materials used in this study were zeolite of Malang (East Java, Indonesia) and shrimp pond water. The best result of NH3 and H2S adsorption obtained at a flow rate of 3 L•min-1. The best adsorption constant value (K) achieved by a flow rate of 3 L•min-1. On the basis of the best value of R2, NH3 and H2S adsorption, it can be classified in the first-order kinetic model with R2 of 0.9763 and a k value of 0.0007 hours-1 with a flow rate of 6 L•min-1. From the data above, it can be calculated that the adsorbent needed in the adsorption of NH3 and H2S in a scale shrimp pond requires 18 kg of Malang zeolite with a column height of 3.62 m of adsorbent, a diameter of 2.07 m, and a column volume of 12.21 m3.
