    摘要: 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

    摘要: An optical imaging system having an optical source located between the object being imaged and the sensor is provided. Such positioning of the source enables provision of compact optical imaging systems. In particular, such systems can have image widths significantly larger than the object to sensor separation. The arrangement of source, imaging assembly and sensor is such that an image of the source is not formed at the sensor. Therefore, the effect of this source positioning on the image of the object at the sensor is a reduction of intensity, as opposed to more objectionable imaging artifacts, such as spurious shadows and/or bright spots. Thus compact optical imaging systems having good image quality are provided, which enables high-fidelity imaging of object to sensor for a wide variety of applications.

    摘要: 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 DOin, an influent nitrate concentration NO3—Nin, and an influent nitrite concentration NO2—Nin; an effluent concentration analyzer for measuring an effluent nitrate concentration NO3—Neff, and an effluent nitrite concentration NO2—Neff′, 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 NO3—Nin, NO2—Nin, NO3—Neff, and NO2—Neff.

    摘要: 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., NOx), and optionally using the effluent concentrations to adjust the nominal amount of methanol being provided.
