A system for pig slurry treatment, where anaerobic digestion, nitrification and denitrification have been integrated in a unique process treatment, has been investigated. This configuration allowed both removal of Chemical Oxygen Demand (COD) and a decrease in nitrogen content. Strategies are reported to bring enough COD to the denitrification system. Results (90% reduction in COD, 99·8% reduction in NH 4 + ‐N and 98·8% reduction in NO 3 − N) show this process could be considered a good alternative to treat these wastes. © 1997 SCI.
