Abstract

A system and method for removing pollutants from wastewater. The system includes a constructed wetland cell in which the filtered wastewater is flowed generally vertically. The flow of wastewater is unsaturated through the wetland cell to aerate the wastewater. The wastewater may be further aerated by a blower or injector. The treated wastewater from the wetland cell is blended with untreated wastewater, then either recirculated through the wetland cell or conveyed to a disposal system.
