Summary
Real-time control (RTC) for urban drainage systems can reduce pollution. This study shows that using pollution data, like turbidity, for RTC offers potential benefits over traditional flow-based methods, especially with available water quality measurements.
Area of Science:
- Environmental Engineering
- Water Resource Management
- Wastewater Treatment
Background:
- Real-time control (RTC) is established for urban drainage systems, primarily focusing on water quantity to mitigate combined sewer overflow (CSO) pollution.
- Advancements in wastewater pollution measurement technologies are increasing the potential for pollution-based RTC strategies.
Purpose of the Study:
- To investigate the benefits of pollution-based RTC compared to flow-based RTC in urban drainage systems.
- To analyze the impact of using turbidity data for RTC based on extensive measurements from Paris catchments.
Main Methods:
- Comparison of pollution-based RTC strategies with traditional flow-based RTC.
- Utilizing extensive turbidity datasets from two Paris urban catchments to evaluate RTC performance.
Main Results:
- Pollution-based RTC demonstrates potential advantages over flow-based RTC for managing urban drainage systems.
- The effectiveness of pollution-based RTC is particularly notable when real-time water quality measurements are accessible.
Conclusions:
- Pollution-based RTC is a promising approach for enhancing the environmental performance of urban drainage systems.
- Availability of water quality data is a key factor in realizing the benefits of advanced RTC strategies.

01:27Controlled-Current Coulometry: Overview
Controlled current coulometry, also known as amperostatic coulometry, is a technique used in electrochemical analysis to measure the quantity of a substance through the controlled passage of current. It involves the application of a constant current to an electrochemical cell containing the analyte of interest. As the current flows through the cell, the analyte undergoes a redox reaction at the electrode surface, resulting in a charge transfer. By monitoring the time required for a certain...

Microbial communities in aquatic ecosystems play a key role in the natural breakdown of contaminants introduced through domestic and industrial effluents. Acting as biological catalysts, these microbes change and mineralize a wide range of organic and inorganic pollutants under different redox conditions.In oxygen-rich surface waters, aerobic heterotrophs lead organic matter breakdown, using oxygen as the terminal electron acceptor to efficiently oxidize substrates to carbon dioxide and water.
01:30Biological Treatment of Effluent and Waste Water
Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...

Estimating microbial growth is essential for understanding population dynamics and environmental adaptations. Indirect methods provide valuable insights by measuring parameters such as turbidity, metabolic activity, and biomass, enabling efficient and reproducible assessments.During exponential growth, microbial cells scatter light proportionally to their biomass, a principle used in turbidity measurements. About one million cells per milliliter produce detectable scattering, which a...
