Published: April 16, 2024

Abstract Recent textile industry expansion has a major environmental impact if not addressed. Being water intensive industry, manufacturing is usually associated with wastewater management challenges. Electrocoagulation (EC) recognized as one of the effective solutions to address these This study aims investigate potential integrating seawater into EC process for treatment, targeting optimal pollutant removal efficiencies. A simple electrolytic reactor was designed efficiency treatments chemical oxygen demand (COD), total suspended solids (TSS), turbidity, and color from at different percentages retention times. Notably, addition only improves but also significantly dilutes pollutants, reducing their concentrations. dual effect enhances dilution optimizes treatment outcome. The highest efficiencies were achieved COD (47.26%), TSS (99.52%), turbidity (99.30%), (98.19%). However, pH, dissolved (DO), electrical conductivity increased increasing times in process. Moreover, Seawater − integration reduces power usage 15.769 Am −2 costs approximately 0.20 USD/m 3 . To assess effects on wastewater, an analysis variance (ANOVA) conducted utilizing Design-Expert 11 software. best model obtained using Central Composite Design (CCD) quadratic ( R 2 = 0.9121), 0.9535), 0.9525), 0.9433). suggests that higher longer effectively eliminate contaminants increase ion
