Abstract
Exemplary systems and methods for treating contaminated water are described. In one instance a method supplies metal salt reagents to a moving media filter in the presence of contaminated water. The method also introduces a waste stream resulting from the moving media filter upstream of the moving media filter effective to lower an average contaminant concentration of effluent water from the moving media filter.
