Study On The Use Of Inverse Fluidized Bed Technology To Treat Wastewater By Eliminating Dye Pollutants From The Al-Kut Textile And Knitting Factory

Abstract

Aim of the Study: The study aims to investigate the effectiveness of Inverse Fluidized Bed Technology (IFBT) for the sustainable removal of terasil blue dye from Al-Kut Textile and Knitting Factory wastewater. Additionally, the research focuses on evaluating the role of adsorbent styles, specifically modified rice husks, in the absorption of terasil blue dye from wastewater.

Mechanism and Methodology: In this work, to remove the terasil blue dye from wastewater coming from Kut Textile and Knitting factory used IFBT to safeguard biofilm and facilitate re-fluidization during power outages in wastewater treatment. An adsorption method has applied to analyze and removal of terasil blue dye from the water treatment in Kut Textile and Knitting Factory. The terasil blue dye adsorption was performed using rice husk as the adsorbent in batch mode by varying parameters such as pH, particle size of rice husks  and it’s dose, contact time and terasil blue dye concentration. Further, kinetics of the adsorption of the dye on rice husks was investigated.

Results: The terasil blue dye removal usi[1]ng rice husks adsorbent showed that various parameters including the pH, particle size of rice husks and it’s dose, contact time and terasil blue dye concentration. The experimental results indicated that the maximum removal efficiency obtained to be 97.15%, at a fixed 200 RPM agitation speed, pH of 7, with 200 minutes contact time, rice husks’ particle size of 1.18 to 2.35 mm and an adsorbent mass of 4 g. The particle size rice husks adsorbent is identified as it positive influences on removal efficiency. Rate constants at varied concentrations are provided to offer insights into the kinetics of the adsorption process. The adsorptive removal efficiencies were obtained at temperature 25±1 °C and initial dye concentration 20 mg/L. Langmuir, Freundlich and isotherm models revealed that Freundlich and isotherm models were best model for terasil blue adsorption. Equilibrium and adsorption dynamics are visually represented in figures, providing a comprehensive overview of the outcomes.

Conclusion: The comprehensive data analysis presented throughout the study underscores the real-world applicability of modified rice husks in the context of improving the efficiency of wastewater treatment processes. The study recommends the application of IFBT for treating Al-Kut Textile and Knitting Factory effluent, specifically targeting color pollutants. This work emphasizes the significance of modified rice husks, and eco-friendly, cost-effective alternatives in wastewater treatment.
