The textile industry is a vital global sector but also a significant source of environmental pollution, particularly through the discharge of dye-laden wastewater. Reactive dyes, such as C.I. Reactive Red 195, are widely used due to their vibrant colors and strong fiber-binding properties. Still, they are difficult to degrade and persist in aquatic ecosystems. The release of untreated dye wastewater poses severe environmental and health risks, including water contamination and ecological imbalance. Developing effective treatment methods is essential to mitigating these impacts and promoting sustainable industrial practices. This study investigates the effectiveness of magnesium chloride (MgCl2) and magnesium hydroxide (Mg(OH)2) as coagulants for the removal of the intense textile dye C.I. Reactive Red 195 from wastewater via chemical coagulation. Coagulation was conducted to determine the optimal coagulant dose, pH, and conditions for maximum color removal efficiency. Results showed that MgCl2 achieved a maximum color removal efficiency of 99.9% at a dose of 1300 mg/L, pH 12. Mg(OH)2 demonstrated a 96% removal efficiency at 2800 mg/L and pH 6. These findings indicate that MgCl2 outperforms Mg(OH)2 under optimal conditions, offering significant potential for high-performance dye wastewater treatment. The study highlights the superior performance of MgCl2 and Mg(OH)2 as coagulants for effective color removal, providing a sustainable solution to address environmental challenges associated with textile dye wastewater.
