Summary

Sewer solids removal at combined sewer overflows (CSOs) relies on flow patterns and sediment settling. A dimensionless efficiency curve, influenced by settling velocity, predicts removal rates for CSO structures, aiding design with frequency analysis.

Area of Science:

  • Environmental Engineering
  • Fluid Mechanics
  • Water Quality Management

Background:

  • Combined sewer overflows (CSOs) release untreated sewage and stormwater, impacting water quality.
  • Effective removal of sewer solids at CSO locations is crucial for environmental protection.
  • Understanding the interplay between hydraulic conditions and sediment properties is key to optimizing CSO performance.

Purpose of the Study:

  • To develop a predictive model for sewer solids removal efficiency at CSO structures.
  • To establish a relationship between flow patterns, sediment characteristics, and removal efficiency.
  • To propose a design methodology for CSO structures based on performance prediction.

Main Methods:

  • Characterizing flow conditions using residence time distribution.

    • A dimensionless efficiency curve effectively predicts removal efficiency as a function of the Hazen number.
    • The settling velocity distribution of sewer sediments is the primary factor influencing the efficiency curve.
    • Nearly identical efficiency curves were observed across different prototype CSO structures under field conditions.

    Conclusions:

    • The proposed methodology provides a robust framework for predicting and designing CSO structures for optimal solids removal.
    • Sediment settling characteristics are a critical determinant of CSO treatment efficiency, simplifying design considerations.
    • Return frequency analysis offers a practical approach for the design of CSO facilities to manage solids removal.
