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. 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.
