Researchers at McMaster University have developed online machine learning models to predict wastewater influent flow rates, particularly during the COVID-19 pandemic. The models outperformed conventional batch learning models in terms of accuracy, exhibiting high R2 values and low errors. The team believes these models can provide reliable decision support for wastewater operators in coping with changing influent patterns. Further validation and exploration of different prediction scenarios are planned for the future.
Online Machine Learning for Stream Wastewater Influent Flow Rate Prediction under Unprecedented Emergencies
Accurately predicting the incoming flow rate is crucial for operators and managers at wastewater treatment plants. This prediction is closely tied to the characteristics of the wastewater, such as BOD, TSS, and pH.
Previous research has shown that data-driven models can effectively predict influent flow rates. However, traditional batch learning approaches needed to be revised, especially in the COVID-19 era when influential patterns saw significant changes.
In response, researchers at McMaster University employed innovative machine learning techniques to enhance the capacity to predict wastewater influent flow rates, particularly within the unique context of the COVID-19 lockdown situation.
Key Findings:
The researchers compared the performance of conventional batch learning models with their online learning counterparts in predicting influent flow rates at two wastewater treatment plants in Canada.
The online learning models consistently outperformed the batch learning models, exhibiting higher R2 values, lower MAPE, and lower RMSE. These models effectively provided reliable predictions amid dynamic data patterns and handled continuous and substantial influent data streams.
The team crafted their models by leveraging several years of hourly influent flow rate data and meteorological data from the two wastewater treatment plants. The new online learning models can provide more robust decision support for wastewater operators or managers to cope with changing influent patterns due to emergencies such as COVID-19.
To further validate the efficacy of the models, the team plans to conduct more case studies and explore a wider range of prediction scenarios.
