🌿 Constructed Wetlands: Subsurface-Flow Wastewater Treatment

Explore how wastewater percolating through a gravel and plant-root bed is cleaned by microbial degradation, and how hydraulic residence time and flow-path tortuosity control treatment efficiency.

Engineering & Materials3DModerate60 FPS

The simulation demonstrates how wastewater percolating through a gravel and root bed is progressively cleaned by microbial degradation, showing how hydraulic residence time and flow-path tortuosity together control pollutant removal efficiency.

🔬 What It Demonstrates

🎮 How to Use

Adjust the hydraulic residence time and flow-path tortuosity sliders to change how long and by what path wastewater travels through the bed, then observe the resulting pollutant removal efficiency at the outlet.

💡 Did You Know?

Some subsurface-flow constructed wetlands have operated continuously for over 20 years treating municipal or industrial wastewater using essentially no energy input beyond the initial pumping of water into the system.
