Preparation of nano zeolite and its application in water treatment

Abstract

Nano-Zeolite was prepared for removing methylene blue from wastewate rby the use of packed bed column. The prepared adsorbent was characterized by XRD and AFM. The characterization result shows that the size of diameter was 95 nm. It was observed that the nano-zeolite was active for the removal of methylene blue as adsorbent. Methylene blue are common wastewater contaminants at industrial installation. The adsorption of methylene blue by nano-zeolite was studied by a pilot plant packed bed column. Continuous flow tests were performed to find the breakthrough times. The breakthrough curve was examined for different parameters such as flow rate (0.5-1-1.5 ml/min), initial concentration (15-25-35 mg/lit) and bed height (4-6-8 cm). Based on these investigations, it appears that the time of the breakthrough increases with an increase in the bed height and decreases with increases in the initial concentrations and flow rates.
