DHS reactor filled with third-generation sponge carriers was evaluated over 1 year.
- class="label">•
Adequate removal of BOD and NH4+-N at an HRT of 0.66 h was achieved.
- class="label">•
Removal rate constants were at least 2.30 h−1 for BOD and FC 4 months after start-up.

The distribution of bacteria along the reactor was inferred by OUR tests.
