Pilot-scale application of shotblast dust for phosphorus removal.

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 μg/L total phosphorus (T-P) water on a daily basis, achieving approximately 60% removal of T-P in 7 days.
