Enhanced Adsorption and Regeneration with Lignocellulose-Based Phosphorus Removal Media Using Molecular Coating Nanotechnology

摘要

The removal of phosphorus in point and non-point-source pollution has become one of the leading problems in water quality since the beginning of the 21st century. Several natural, domestic, and industrial treatment systems already exist, but with very limited efficiencies and serious procedural defects. Lignocellulose-based Anion Removal Media (LAM) was developed in association with iron nanocqating technology as means of phosphorus adsorption from various concentrations of contaminated water. Results revealed that trivalent iron coated lignocellulose pellets can be used to effectively remove phosphorus contaminants from point and non-point-source polluted water. Removal capacities of pelletized cotton media surpass existing materials for phosphorus removal by at least 22 times, while remaining both efficient and cost effective. The materials were also investigated for regeneration, yielding high removal capacities even after the fifth regeneration. Treatment methodology and outlines are proposed, and procedural mechanisms are explored in this study. An economic evaluation of this technology is also assessed for a practical application of LAM to pointon-point-source polluted water.
