Abstract: A method of operating a waste water treatment plant (WWTP) having at least one of an aerobic digester (AD) and a membrane bioreactor (MBR) is described. The method of operating AD is comprised of monitoring and controlling AD in real-time using an online extended Kalman filter (EKF) having a online dynamic model of AD. The EKF uses real-time AD measured data, and online dynamic model of AD to update adapted model parameters and estimate model based inferred variables for AD, which are used for AD control by AD control system having supervisory and low-level control layers. The method of operating MBR is similar to that of AD. The supervisory control ensures the WWTP satisfying the effluent quality requirement while minimize the operation cost. A WWTP having at least one of AD or MBR is disclosed. The method of operating a WWTP can be implemented using a computer.

Abstract: According to some embodiments, data associated with the operation of a desalter vessel (150), adapted to receive a raw crude input and a water input and facilitate creation of a desalted crude output and a salt water output, may be stored in a computer storage device (630). A computer processor (610) may determine at least one parameter associated with the data in the computer store. The computer processor (610) may then automatically calculate, based on the determined parameter and a physics-based dynamic desalter model (400), an adjustment value for a second parameter associated with operation of the desalter vessel. Using the automatically calculated adjustment value, the computer processor (610) may automatically generate and transmit an indication of the adjustment value so as to improve operation of the desalter vessel (150).

The circuit interrupter includes separable contacts (24), a trip mechanism (26), a bimetal (30), a microprocessor (12), a series arc detection sequence (14), a low-pass filter circuit (38), and a high-pass filter circuit (36). The trip mechanism selectively opens the separable contacts when activated. The series arc detection sequence is resident on the microprocessor and includes a plurality of series fault detection algorithms (72, 76, 80, 84). The low pass filter circuit provides a low-pass signal (48) to the series arc detection sequence. The high-pass filter circuit provides a high-pass signal (46) to the series arc detection sequence. The sequence selects a particular algorithm from the plurality of algorithms based on the low-pass signal. The sequence calculates a plurality of statistical features from the high-pass signal and sends an output signal (54) to activate the trip mechanism based on a comparison of the plurality of statistical features to the particular algorithm.
