Performance evaluation reveals that adsorption and Fenton processes effectively reduce COD and color in dye manufacturing wastewater, pointing to cost-effective treatment alternatives.
Key Points
Color removal reached approximately 98%–99% in both wastewater samples using the Fenton process, demonstrating high effectiveness.
Adsorption achieved over 64.2% COD removal at optimal conditions of pH 5 and 20 g L −1 activated carbon.
The estimated cost for dye wastewater treatment was $10.58–15.53 m −3 using adsorption and $20.57–22.89 m −3 via Fenton oxidation.
Both methods offer significant reductions in chemical oxygen demand (COD) and color, ensuring compliance with discharge regulations.
