A single aerobic reactor is currently installed at the Quinera WWTW. It is aerated by means of four surface mechanical aerators mounted on concrete bridges, driven through gearboxes by 35 kW motors. The WWTW currently receives an inflow of between 6 and 7 M/d ADWF, but will be expanded to a capacity of 18 M/d ADWF. This will require the addition of a second aerated reactor rated at 9 M/d, and increased aeration capacity of the existing reactor to the same level.
