This research project presents the comprehensive process design of an adsorption unit optimized for the removal of synthetic dyes from textile industry wastewater using natural and modified zeolites. Textile effluents represent a significant environmental challenge due to their high organic load, persistent toxicity, and chemical stability, which often resist conventional treatment methods. To enhance removal efficiency, this study explores the structural transformation of natural zeolites through targeted surface modifications. Characterization via X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) confirmed that these modifications successfully altered the bulk morphology into high-performance nano-sheets. This transition to a nano-scale structure significantly increased the available surface area and active sites, facilitating a more rapid and thorough capture of contaminants. Experimental data reveals that the adsorption process adheres to first-order kinetics (Order = 1), indicating that the removal rate is directly proportional to the dye concentration. Results demonstrate that the modified zeolite nano-sheets are the superior adsorbent, exhibiting significantly higher efficiency and faster kinetics compared to their natural counterparts. These findings offer a scalable and sustainable solution for advanced industrial wastewater management, providing a clear path toward meeting stringent environmental discharge standards. XRD Analysis of Morphological Transformation The transition from bulk natural zeolite to engineered nano-sheets is characterized by significant peak broadening in the diffraction patterns. Governed by the Scherrer equation, this broadening serves as mathematical confirmation that the crystal dimensions have been reduced to the nanoscale. Additionally, the high aspect ratio of the nano-sheets often induces a "preferred orientation," resulting in increased relative intensity for specific basal plane peaks. Despite these morphological shifts, the preservation of characteristic Bragg peaks confirms that the aluminosilicate framework remains structurally stable after surface modification, providing statistical validation that complements the visual evidence observed in SEM imaging. Research Objectives: The primary goal of this study is to engineer a high-efficiency adsorption system for industrial wastewater treatment. The specific objectives are as follows: To utilize surface modification techniques to transition bulk natural zeolites into high-surfacearea nano-sheets. To verify the phase purity and structural integrity of the modified framework using X-ray Diffraction (XRD). To analyze the morphological shift and surface texture of the resulting nano-sheets through Scanning Electron Microscopy (SEM). To evaluate the adsorption kinetics and confirm a first-order reaction (Order = 1) to determine optimal operational parameters for the unit design. To demonstrate through comparative analysis that modified zeolites are the more effective adsorbent for high-concentration dye removal compared to natural minerals.
