Study
- Citation
- Erickson, A. J., Gulliver, J. S., & Weiss, P. T. (2012). Capturing phosphates with iron enhanced sand filtration. Water Research.
- Study description
- This study investigated the effectiveness of iron filings in sand filtration system for the removal of phosphates. The study looked at both the percentage of phosphates captured by the iron filings and the impacts on hydraulic conductivity as a result of the iron filings.
Response
- Cause term/trajectory
-
Sediment quality - metals
(Increase)
- Cause description
- Increased iron filings in a sand filtration system. The study investigated the impact of 0%, 0.3%, 2% and 5% iron filings in sand filtration media.
- Effect term/trajectory
-
Sediment quality - other
(No change)
- Effect description
- Hydraulic conductivity - the incorporation of iron filings and the increased capture of phosphates onto the iron filings was found to have no significant effect on hydraulic conductivity of the media.
