Conclusions <strong>IFAS</strong> can be applied to existing secondarysystems to reduce effluent ammoniaconcentrations. <strong>IFAS</strong> increases sludge age, increasing thetotal inventory of nitrifiers, without increasingloads to secondary clafifiers. These systems are very robust. <strong>Fixed</strong> media <strong>IFAS</strong> systems (such as theAccuFAS system) can be added withoutaffecting existing hydraulic profiles.
