Effectiveness of Lignocellulose Nanofibers (LNCFS) for removing nitrite, nitrate, and phosphate from Gamishan wastewater

Abstract

This study investigates the effectiveness of Lignocellulose Nanofibers (LNCFs) as a sustainable adsorbent for the removal of nitrite, nitrate, and phosphate from aquaculture wastewater, specifically focusing on fish farms in Gamishan. We optimized several key parameters, including pH, contact time, temperature, and adsorbent dosage, to determine the optimal conditions for pollutant removal. The results indicate that the highest removal efficiencies were achieved at a pH level of 6.5, with a contact time of 67 minutes, a temperature of 30 ^○C, and an adsorbent dosage of 400 mg. Specifically, the removal rates were found to be 93 % for nitrate, 95 % for nitrite, and 96 % for phosphate. These findings demonstrate that LNCFs are not only effective in reducing these pollutants but also possess significant potential as a sustainable solution for wastewater treatment in aquaculture systems. The study emphasizes the critical role of optimizing operational parameters to maximize pollutant adsorption. Furthermore, the successful application of LNCFs in aquaculture practices could enhance environmental sustainability by promoting healthier aquatic ecosystems and effectively addressing the challenges posed by nutrient loading in water bodies. This research lays the groundwork for future investigations into the broader applicability of LNCFs in various wastewater treatment contexts, suggesting that their integration into aquaculture practices could lead to substantial improvements in water quality management and ecosystem health.
