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.
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.
Sliders for hydraulic residence time and flow-path tortuosity
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.
