Abstract: In this research, three anaerobic filters were operated with a 9 hour hydraulic detention time, and its effluent was disposed on four sand filters' bed in different application rates. On the first sand filter, 50 L.m-2 were disposed once a day. On the second, the third and the fourth filters, the same load was disposed in twice, three and four times a day, distributed between 9 am and 4 pm, corresponding to rates of 100, 150 and 200 L.m-2.d-1. After the sand filter, the effluent was conducted to the denitrification reactors filled up with grit. As result, the sand filters have shown a great nitrification capacity and, after the external carbon adding, the denitrification reactor, where 50 L.m-2 was disposed a day, showed a decrease of 43.5% in N-total concentration.
