Impact/Purpose:
Phosphorus pollution arises from various sources, including runoff that contains human waste and fertilizers from farms, livestock, and industry. The formation of algal blooms also may be associated with release of toxins into the environment, causing loss of biodiversity, fish kills, and deterioration of water quality. In this study, shotblast dust was applied as a novel, potentially cost-effective adsorbent for removing phosphorus from water. This study investigated the efficacy of shotblast dust to treat phosphorus-laden water in a pilot-scale reactor and evaluated its cost-effectiveness in remediation of aqueous phosphorus in field systems.
Description:
Phosphorus contamination is a global issue, and cost-effective remediation is sought for removing phosphorus from water. We applied a novel use of waste material called shotblast dust in a pilot-scale reactor to remove phosphorus from water. Results indicate that shotblast dust was effective in treating phosphorus-laden water with 132 kg of the material treating 568 liters of 220 ug/L total phosphorus (T-P) water on a daily basis, achieving approximately 60% removal of T-P and 70% removal of orthophasphate in 7 days.
