Biochar-Reinforced Rubber Foam as an Adsorbent for Simultaneous Removal of Multiple Nutrients from Wastewater: Ion-Dependent Mechanisms and Engineering Performance
Simultaneous removal of ammonium (NH4 +), nitrate (NO3 –), nitrite (NO2 –), and phosphate (PO4 3–) from secondary effluent remains challenging in advanced wastewater treatment. Biochar-reinforced natural rubber latex foam (NRLF) composites were fabricated via the Dunlop process as structured, particle-retaining adsorbe...
