Effect of recycle-to-influent ratio on activities of nitrifiers and denitrifiers in a combined UASB–activated sludge reactor system

A laboratory study using a combined upflow anaerobic sludge bed (UASB)–activated sludge (AS) reactor system was undertaken to explore the effect of recycle-to-influent ratio ( R e = 1, 2, and 3) on the activities of nitrifiers and denitrifiers. Suspended-solids pre-settled piggery wastewater was use...
