This study evaluates the effectiveness of a double-layer capping system composed of biochar (BC) and zeolite (ZE) with Non-woven Fabric mats (NWFM) in controlling nutrient fluxes and improving water quality in Lake Hashenge, Ethiopia. Three configurations were tested: NWFM/ZE/BC (ZE above BC), NWFM/BC/ZE (BC above ZE), and an uncapped control. Laboratory experiments assessed nutrient release (NH₄-N, NO₃-N, T-N, PO₄-P, T-P) under two temperatures (16°C and 24°C) over 60 days. Capped setups NWFM/ZE/BC and NWFM/BC/ZE significantly reduced NH₄-N fluxes, achieving 2.27 ± 1.08 mg/m² day and 1.5 ± 0.39 mg/m² day at 16°C, and 1.82 ± 0.66 mg/m².day and 2.34 ± 1.64 mg/m².day at 24°C, respectively. T-N flux followed a similar trend, with NWFM/ZE/BC achieving the lowest value at 16°C (1.03 mg/m² day) and the highest flux observed in uncapped conditions at 24°C (5.02 ± 1.36 mg/m².day). The NWFM/ZE/BC configuration reduced NH₄-N flux by 95%, retained up to 98% of phosphorus, and mitigated temperature-dependent nutrient release while maintaining dissolved oxygen (DO) and reducing chemical oxygen demand (COD). These findings underscore the potential of such capping materials for restoring eutrophic ecosystems and highlight the need for integration with catchment management practices. Field trials are recommended to validate long-term performance.
