Abstract/Contents

Abstract: To address the issue of excessive riparian phosphate pollution, scaffolds of calcium alginate and Magnesium-Aluminum Layered Double Hydroxides (MgAl- LDH) composite filaments were constructed.
• Adheres to dissolved phosphates, preventing harmful algal blooms
• Max absorption capacity: 127.5 mg P/gram of scaffold
• More effective than beads: higher surface area/volume
• Inexpensive: $0.04/gram
• Wide deployment opportunities: SWDP, WWTP, catch basins, farm irrigation
• Recycle: slow-release fertilizer capsules
- Hinders phosphate runoff cycle
- Reduce mined phosphate demand
- Offset fertilizer costs for farmers
• Expanded pollutant suite possible: nitrates, heavy metals and bacteria
