Abstract:

When considering upgrading an existing wastewater treatment plant to nitrification, higher degrees of nitrification, year-round nitrification, or incorporation of higher levels of total nitrogen control; challenges of space constraints; and cost of the improvements are often significant issues driving the project towards consideration of innovative, smaller-footprint processes. The integrated fixed-film activated sludge (IFAS) process may be your best option. This paper steps through the logic of when and where IF AS may be an attractive alternative; considerations that must be weighed for thorough evaluation of IF AS and its myriad configurations and equipment options; operational considerations and cost elements that should be considered; and an approach to procuring the IF AS equipment/system options competitively. Some process design guidelines are also incorporated where that information is pertinent to the overarching theme of how one considers this process option in light of other alternatives.
