Abstract
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.
Claims18
A wastewater denitrification system, comprising:
- an influent concentration analyzer configured to measure an influent dissolved oxygen concentration, an influent nitrate concentration and an influent nitrite concentration;
- an effluent concentration analyzer configured to measure an effluent nitrite concentration;
- and
- a feed chemical controller configured to provide a feed chemical at a controlled rate,
- in which the feed chemical controller is responsive to one or more signals provided by an automated control loop that, in turn, is responsive to signals from the influent concentration analyzer and the effluent concentration analyzer, which signals relate to (i) at least two of the influent nitrate concentration, the influent nitrite concentration and the influent dissolved oxygen concentration, and (ii) the effluent nitrite concentration.
A wastewater denitrification system, comprising:
- an influent concentration analyzer configured to measure an influent dissolved oxygen concentration, an influent nitrate concentration and an influent nitrite concentration;
- an effluent concentration analyzer configured to measure an effluent nitrite concentration;
- and
- a feed chemical controller configured to provide a feed chemical at a controlled rate,
- in which the feed chemical controller is responsive to one or more signals from the influent concentration analyzer and the effluent concentration analyzer.
A wastewater denitrification system comprising:
- an influent concentration analyzer;
- an effluent concentration analyzer;
- and
- a feed chemical controller that controls the rate at which a feed chemical is provided for denitrification of wastewater in response to (i) signals representative of at least two of an influent dissolved oxygen concentration, an influent nitrate concentration and an influent nitrite concentration, as measured by the influent concentration analyzer, and (ii) a signal representative of an effluent nitrite concentration, as measured by the effluent concentration analyzer.
