World-Water - Integrated Fixed-Film Activated Sludge (IFAS) System - Brochure

With our integrated fixed-film activated sludge (IFAS) technology, we can upgrade conventional activated sludge systems to meet new effluent ammonia or total nitrogen and phosphorous limits. By incorporating specialized bio-media into portions of the existing aerobic zones, we can cultivate the slower growing AOB/NOB bacteria to aid in ammonia removal.
