Reed beds provide an environmentally friendly solution to sludge pollution management
Graphical summary. Credit: Soil and Environmental Health (2024). DOI: 10.1016/j.seh.2024.100083 Sludge, a byproduct of wastewater treatment, often contains hazardous substances such as heavy metals and excess nutrients, posing serious risks to the environment and health if not properly treated. Traditional processing methods rely heavily on chemicals and energy-intensive processes, making them less sustainable. Sludge treatment reed beds (STRBs) provide a…
