Area of Science:
- Environmental Engineering
- Water Treatment Technologies
- Chemical Kinetics
Background:
- China's waterworks face challenges meeting new trihalomethanes (THMs) regulations.

Main Methods:
- Developed a comprehensive kinetic model incorporating physical, biological, and chemical processes.
- Utilized a Petersen matrix for model representation and mass balance equations.
- Employed the Hornberger-Spear-Young (HSY) algorithm for model identification.
- Validated the model using field data from Qingzhou Waterworks, Macao.
Main Results:
- The integrated waterworks model accurately predicted THM levels and associated water quality parameters.
- Model parameters aligned with existing literature values and were interpretable.
- The model demonstrated utility for management purposes despite field data uncertainties.
Conclusions:
- The developed model is a valuable tool for evaluating the impact of THM regulations on water treatment.
- The model provides reliable predictions for optimizing water treatment processes and ensuring compliance.
- Further application of the model can aid in proactive water quality management in China.

01:12Modeling and Similitude
Scaled modeling is a fundamental technique in engineering, enabling the study of large and complex systems by creating smaller, manageable replicas that recreate critical characteristics of the original. In hydrology and civil infrastructure, for example, scaled models of dams help analyze water flow, turbulence, and pressure. This method allows for accurate predictions of real-world behavior within a controlled environment, significantly reducing the cost and time involved in full-scale...
01:30Typical Model Studies
Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.
01:28Phase Diagrams of Ternary Systems
Consider a ternary system, which is composed of three components: water (W), ethanoic acid (E), and trichloromethane (T). Here, Ethanoic acid (E) is fully miscible with both water (W) and trichloromethane (T), meaning it can mix entirely with either of them. However, water and trichloromethane have partial miscibility, meaning they can only mix to a certain extent, beyond which two separate phases will form.The phase diagram of a ternary system is represented as an equilateral triangle, where...

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.
