Iron-enhanced sand filters are filtration best management practices (BMPs) that incorporate filtration engineered media mixed with iron. The iron removes several dissolved constituents, including phosphate (dissolved phosphorus), from stormwater.Iron-enhanced sand filters may be particularly useful for achieving low phosphorus levels …

Abstract We investigated experimentally the tribological behavior of tailing grain contacts using a micromechanical apparatus which allows high precision of force and displacement measurements to derive contact stiffness. A technique was developed to apply biopolymer coating to the grain surfaces and the emphasis of the study was …

An iron-enhanced sand filter basin is similar to a surface sand filter with iron mixed evenly throughout a portion of the filtration media. Surface sand filter design and operating parameters also applicable to iron-enhanced sand filter basins include the use of a flow splitter to control inflow volume;

Iron-sand filter bed clogging poses the greatest operational and maintenance challenge of all filters. Poor drainage of the filter due to clogged filter surface, inlet, outlet, and underdrains, and persistent tailwater has the potential to cause the iron to foul and move within or be lost from the filter bed.
