Actiflo Ensures Compliance For Coal Yard Runoff

Contaminated storm water resulting from rainfall and snowmelt was previously collected in two large basins. As the basins approached capacity, the storm water was treated in situ and dis-charged to the river. The new NPDES permit for the discharge contained limitations for total suspended solids, iron and manganese that the existing treatment system could not consistently achieve, along with a compliance deadline. To further complicate matters, the amount of space available for the installation of additional treatment system components was limited.
