Abstract
The food industry, including nata de coco production, generates wastewater with high concentrations of organic pollutants, as indicated by elevated chemical oxygen demand (COD) and biochemical oxygen demand (BOD) values. If untreated, such wastewater poses serious environmental risks. This study evaluates the effectiveness of an ozone/hydrogen peroxide (O₃/H₂O₂) Advanced Oxidation Process (AOP), known as the peroxone system, for reducing organic pollutants and total suspended solids (TSS) in liquid nata de coco wastewater (LNW). A total of 19 experimental runs were conducted by varying the H₂O₂ dosage (0–1.0 mL), ozonation time (0–30 minutes), and initial pH (5–10), with 300 mL of wastewater treated per run. Ozone was supplied using a corona discharge-based OZX-3000D generator under ambient temperature and atmospheric pressure. Standar Nasional Indonesia (SNI) were applied to measure COD, BOD, and TSS concentrations before and after treatment. Pollutant removal efficiency was analyzed using paired t-tests and multiple linear regression (MLR) to assess the relationship between process parameters and treatment performance. The optimum operating conditions were determined as pH 7, 0.6 mL H₂O₂, and 15 minutes ozonation time, yielding maximum removals of 84% COD, 80% BOD, and 80% TSS. Results were statistically significant (p < 0.05), while high Coefficient of Determination (R²) values (0.976 for BOD, 0.876 for COD, and 0.823 for TSS) confirmed strong correlations between input parameters and treatment outcomes. Compared to previous studies on food industry wastewater, the peroxone system demonstrated equal or superior efficiency, with the added advantages of operating at near-neutral pH, shorter reaction times, and lower chemical input. These features make it particularly suitable for small- to medium-scale industrial applications and decentralized wastewater treatment
