Experimental Investigation On Treatment Of Industrial Wastewater Using Water Hyacinth For Water Quality Improvement

Abstract

Industrial Wastewater Generated From Manufacturing And Processing Industries Contains High Concentrations Of Organic Matter, Dissolved Solids, Nutrients, Oil And Grease, And Other Pollutants That Pose Serious Environmental And Public Health Risks. This Study Experimentally Investigates The Effectiveness Of Water Hyacinth (Eichhornia Crassipes) As A Low-cost And Eco-friendly Phytoremediation Technique For Improving The Quality Of Industrial Wastewater. Wastewater Samples Were Collected From An Industrial Source And Treated Using A Tank-based Water Hyacinth System Over A Period Of Six Months. Key Water Quality Parameters Such As PH, Total Dissolved Solids (TDS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Oil And Grease, And Nitrate Concentration Were Analyzed At Monthly Intervals. The Results Indicated A Gradual And Significant Improvement In Water Quality, With Reductions Of Approximately 47.6% In TDS, 52.5% In BOD, 54.2% In COD, 48.3% In Oil And Grease, And 44.3% In Nitrate Concentration. The Findings Demonstrate That Water Hyacinth Is An Effective, Economical, And Sustainable Treatment Option For Industrial Wastewater, Particularly Suitable For Decentralized Treatment Systems.
