Iron-enhanced sand filters are filtration Best Management Practices (BMPs) that incorporate filtration media mixed with iron. The iron removes several dissolved constituents, including phosphate, from stormwater. Iron-enhanced sand filters may be particularly useful for achieving low phosphorus levels needed to improve nutrient impaired waters. Iron-enhanced sand filters could potentially include a wide range of filtration BMPs with the addition of iron; however, iron is not appropriate for all filtration practices due to the potential for iron loss or plugging in low oxygen or persistently inundated filtration practices.
- The articles comprising the Iron enhanced sand filter section have been compiled into a pdf document using the Create a Book function in the left toolbar. NOTE that this document has not been formatted in the manner typical for a pdf document and instead compiles the different articles from the wiki. There may therefore be unusual formatting. However, the full contents of the iron enhanced sand filter section are contained within this pdf document. To access the pdf, link to: File:Iron enhanced sand filter.pdf
- The individual articles comprising this section on iron enhanced sand filter trench may be viewed as a single article. Note: Due to an unresolved bug, when viewing a formula in a combined article, the math markup (used for equations) is displayed. Please ignore the markup. Thanks.
