Disclosed herein are systems and methods of analyzing data acquired from a water plant, both historical and in real-time, making determinations about process and asset health diagnosis and anomaly detection using advanced techniques, and controlling the plant and/or providing alerts based on such determinations.
Waste water treatment plants and drinking water plants need daily monitoring and operation to ensure the process health to meet the effluent standards and lower the operation cost at the same time. Treatment process diagnosis, data anomaly identification, equipment health diagnosis are key steps for operators to make the correct decisions or control actions. Traditionally, water treatment is a long process with large volumes of data generated from sensors or lab tests such as water quality sensors and assets sensors. Currently, most of the daily diagnosis is made by human based on experience and simple data analysis such as threshold judgement. It is difficult to handle multi-parameters at the same time to analyze the possible sensor fraud or health issues to make the best control all the time. Different people making such decisions and judgments may result in different quality levels of water plant management. Furthermore, large margins are kept during plant design and operations based on experience to make sure the effluent standard is met even under the worst case, which leads to much higher operation cost. An intelligent diagnostic system can help people improve efficiency in daily operation and improve the quality of diagnosis which is comprehensive and reliable. Such a system could also help to improve the operation quality, prevent the failures timely and ultimately increase the benefits.
Therefore, a method and system is desired to quickly, continuously and accurately diagnose process and asset health, detect anomalies, and dynamically control the water treatment process cost-effectively with high quality.
Disclosed herein are intelligent methods or systems for process and asset health diagnosis and anomaly detection in wastewater treatment plants or drinking water plants. The system includes the entire diagnosis methodology to determine the plant health status including process and asset health. The results can be pushed out to a user interface as notifications or to a control system for actions taken in accordance with the results. Data for diagnosis can be obtained from one or more of influent sensors, assets sensors, process sensors, effluent sensors, lab tests, plant dynamic or static simulated model, any other models to simulate or predict the plant process or asset, and the like. Compared with traditional human experience or simple threshold method, the systems and methods described herein combine a series of advanced methods or algorithms to get more comprehensive and reliable diagnosis results. The systems and methods described herein provide an intelligent water plant diagnosis service or product to end user for better monitoring and control and management of daily operations. The algorithms or models can be, but are not limited to supervised learning, unsupervised learning, risk recognition, anomaly detection, statistical analytics, cross validation, and the like. All the algorithms or models could be continuously upgraded as data loads.
Furthermore, methods and systems are disclosed herein for dynamic control and operation of a water plant using predictive analytics with synergy of physics-based model and plant data-based models/algorithms. The water treatment plants include waste water plants and drinking water plants. Embodiments of the system acquire plant data to capture the plant dynamic features, analyze in its intelligent module of “plant health diagnosis” and “advanced controller” to predict the plant performance proactively and optimize its control and operation, and then pass the optimized control strategy to the plant lower control system for real-time control. The intelligent module is where the synergy of plant physics-based model and data-based model/algorithm lies. This intelligent control system improves the plant operation and control to the knowledge and data-based level from traditional experienced level, and it can handle much more complex situations, and make the plant control and operation more reliable and effective. The intelligent control of water treatment control can effectively utilize the plant facility based on its dynamic status, and balance the effluent quality and plant operation cost, and improve the plant productivities and reliability. Also disclosed herein is an approach or methodology to quickly solve the optimal control strategies or parameters with a certain level of safety.

Supervised learning is one machine learning task of inferring a function from labeled training data. The training data can be obtained from the historical or online database generated from water plant sensors or simulated models. The labels can be the plant health status, risk level, anomaly, problem, root cause, or mitigation solution. These models learn the diagnosis rules from historical events, human experience, or simulated scenarios once they are digitalized into a dataset. Then, the models are implemented to determine or predict plant health in daily operation. The algorithms used can be one or more of Decision tree, Gradient Boosting Decision Tree (GBDT)/Gradient Boosting Decision Tree (GBRT)/Multiple Addition Regression Tree (MART), Artificial Neural Network, Convolutional Neural Network (CNN), Recurrent Neural Network (RNN), Long Short Term Memory (LSTM), Gated Recurrent Unit (GRU), Support Vector Machine including all kinds of kernel methods such as RBF, Naïve Bayesian Classification, Maximum Entropy Classification, Ensemble Learning Methods including Boosting, Adaboost, Bagging, Random Forest, Linear Regression, Logistic Regression, Gaussian Process Regression, Conditional Random Field (CRF), Compressed Sensing methods such as Sparse Representation-based Classification (SRC), and the like.
Unsupervised learning comprises using the diagnosis rules from historical or online database without labeled responses. This is a complementary method to supervised learning. More unlabeled dataset could be involved into the diagnosis than are used with supervised learning. Plant health status, risk level, anomaly, problem, root cause or mitigation solution may also be identified by unsupervised learning in some extent. The algorithms used in unsupervised learning can be one or more of Hierarchical clustering, k-means, mean-shift, spectral clustering, Singular value decomposition (SVD), Principal Component Analysis (PCA), Robust Principal Component Analysis (RPCA), Independent Component Analysis (ICA), Non-negative Matrix Factorization)(NMF), Trend Loess Decomposition (STL), Expectation Maximization (EM), Hidden Markov Model (HMM), Gaussian Mixture Model (GMM), Auto-Encoder, Variational Auto-Encoder (VAE), Generative Adversarial Nets (GAN), Deep Belief Network (DBN), Restricted Boltzmann Machine (RBM), Least Absolute Shrinkage and Selection Operator (LASSO), and the like.
Cross validation of the sensor value with the corresponding value from simulated model's outputs or lab test results is a method to determine sensor fraud. A significant gap between sensor value and simulated soft sensor or lab test results can provide evidence of sensor fraud. By using cross-validation, sensor fraud can be identified, calibrated (to correct), removed or replaced in order to ensure data quality.
Anomaly detection is a method to determine anomaly or outliers from normal dataset. The anomaly may include sensor fraud data, abnormal influent or effluent water quality, abnormal energy consumption or control parameters. The anomaly may not necessarily exist in training dataset and it is also not possible to cover all the anomaly scenarios in the training dataset. Therefore, this is a suitable method to identify an anomaly that has not happened before. The algorithms used can be one or more of Maximum-Likelihood Estimation, Kalman Filter, Trend Loess Decomposition (STL), Autoregressive Integrated Moving Average model (ARIMA), Exponential Smoothing methods such as Holt-Winters Seasonal method, and the like.
Risk recognition is a method to determine the high risk events in water plants. These kinds of events do not occur often, but require a special analysis to identify an include events such as sludge poisoning, sludge expansion, max plant capacity exceedance or heavy metal poisoning. Models are created to recognize these high risk events. The models include but are not limited to dissolved oxygen consumption rate, air flow to dissolved oxygen response model, generated sludge health index, or maximum influent tolerance model. By this way, the special pattern of high risk events can be identified for warning or problem identification.
As shown in
Returning to the flowchart of
Alternatively or concurrently, taking one or more actions based on the health diagnosis or anomaly detection for the water plant may comprise providing data about the health diagnosis or anomaly detection for the water plant to a control system that controls at least a portion of the water plant where the data about the health diagnosis or anomaly detection for the water plant is used by the control system to change at least one parameter of operation of the water plant.
“Plant health diagnosis” model has plant design and retrofit data and information as its basic input, and it will continuously receive dynamic influent data including flowrate and quality during operation. With all these information, the plant health diagnosis module, as described above, continuously checks the plant health status and if it's necessary will perform operation optimization tasks. Once an optimization need is identified, it will trigger the “optimizer” of the advanced controller and send the operation constraints to the “optimizer”. Machine learning technique are used in the plant health diagnosis module to identify the operation constraints for control optimization based on the plant dynamic status and narrow the optimization space.
The “optimizer” is based on the machine learning technique and it enhances the resolver of the advanced controller. It integrates constraints produced from “plant health diagnosis” module, water treatment knowledge, plant data and results of previous optimizing scenario to dynamically generate next optimizing instance for the plant operation optimization model to run and estimate. This is desirable compared with existing technique with fixed pre-set scenario matrices to find optimal point in terms of total number of scenarios to run and the speed to find the optimal point.
The plant operation optimization model is a collection of models representing the biological, chemical, hydraulic, etc. features of plant units and operations. It is firstly set up based on the unit/operation mechanism/physics and then calibrated with the plant specific data and information to form the virtual copy of the plant. This enables it mimic the plant behavior and accurately monitor and predict the plant performance including key performance indicators (KPIs) once information on influent flowrate and quality is received. This module includes but is not limited to mechanistic physics-based predictive models of biokinetics like activated sludge models (ASMs), chemical dosing for alkalinity adjustment, phosphorous control, extra carbon introduction, aggregation/flocculation, settling, oxygen transfer, aeration control, pump control, etc. and their individual and overall simplified ones. The plant KPIs include but not limit to effluent quality like total suspended solids (TSS), BOD (biochemical oxygen demand), COD (chemical oxygen demand), TOC (total organic carbon) TP (total phosphorous), TN (total nitrogen), NH3-N (ammoniacal nitrogen); energy consumption/cost; chemical consumption/cost; WAS generation/deposal cost; overall cost; and the like.
