The disclosed process and system are used for the denitrification of wastewater. The system comprises: an influent concentration analyzer for measuring an influent dissolved oxygen concentration, an influent nitrate concentration, and an influent nitrite concentration; and a feed chemical controller for providing a feed chemical at a controlled rate. The feed chemical controller is responsive to one or more output signals provided by an automated control loop that accepts input signals from the influent concentration analyzer, which input signals relate to at least two of the influent nitrate concentration, the influent nitrite concentration, and the influent dissolved oxygen concentration.

Denitrification process

Denitrification system

The disclosed process and system are used for the denitrification of wastewater. The system comprises: an influent flow meter for measuring an influent flow Q; an influent concentration analyzer for measuring an influent dissolved oxygen concentration DO, an influent nitrate concentration NO&#x2014;N, and an influent nitrite concentration NO&#x2014;N; an effluent concentration analyzer for measuring an effluent nitrate concentration NO&#x2014;N, and an effluent nitrite concentration NO&#x2014;N, and a feed chemical controller for providing a feed chemical at a controlled rate. The feed chemical controller is responsive to one or more output signals provided by an automated control loop that accepts input signals from the influent concentration analyzer and the effluent concentration analyzer, which input signals relate to at least NO&#x2014;N, NO&#x2014;N, NO&#x2014;N, and NO&#x2014;N.

Wastewater denitrification system

A process and system for denitrification of wastewater. The process includes the steps of measuring an influent flow rate, measuring influent concentrations of nitrates, nitrites, and dissolved oxygen in the wastewater, and using the influent concentrations to determine a nominal amount of methanol to be provided for denitrification. The invention also contemplates the measurement of effluent concentrations of nitrates and nitrites (i.e., NO), and optionally using the effluent concentrations to adjust the nominal amount of methanol being provided.
