An automatically controlled alternate oxic?anoxic process for small municipal wastewater treatment plants
A patented automatic control device was applied to management of an alternate oxic?anoxic process in a small wastewater treatment plant (700 PE). The control system enabled the optimal time?length of the aerobic and anoxic phases to be determined by analyzing the dissolved oxygen and the oxidation?reduction potential data. Moreover, also a time set point was introduced to establish the maximum length for the two phases. Results showed high performances in biological nitrogen removal (0.7?5.2 mg of NO3?N L-1 in the effluent) and a reliable control of the treatment process also during wet weather events. In comparison with extended aeration plants of similar size, lower energetic consumption was observed, generally <200 Wh PE-1 day-1. The automatic control device was a reliable system that gave a good performance in a small wastewater treatment plant with low investment and managing costs.

Abstract

A patented automatic control device was applied to management of an alternate oxic?anoxic process in a small wastewater treatment plant (700 PE). The control system enabled the optimal time?length of the aerobic and anoxic phases to be determined by analyzing the dissolved oxygen and the oxidation?reduction potential data. Moreover, also a time set point was introduced to establish the maximum length for the two phases. Results showed high performances in biological nitrogen removal (0.7?5.2 mg of NO3?N L-1 in the effluent) and a reliable control of the treatment process also during wet weather events. In comparison with extended aeration plants of similar size, lower energetic consumption was observed, generally <200 Wh PE-1 day-1. The automatic control device was a reliable system that gave a good performance in a small wastewater treatment plant with low investment and managing costs.
