In 1997 the North Buffalo Water Reclamation Facility in the City of Greensboro could not consistently meet their winter permit limit for ammonia-nitrogen. They decided to try a full scale demonstration of Integrated Fixed-Film/Activated Sludge (IFAS) using a new fabric media called BioWeb. IFAS technology adds a high surface area synthetic media directly into the aeration basins of a conventional activated sludge plant. The additional media yields an attached growth bacterial population that increases the total biomass in the system without overloading the clarifiers. This can be extremely useful and cost-effective for increasing capacity or for increasing treatment levels at existing plants. North Buffalo added the media to one of their four parallel aeration flow trains and have complied with their ammonia-nitrogen permit ever since.
