Article Synopsis
  • Wastewater Treatment Plants produce a large amount of sludge, necessitating cost-effective and eco-friendly management methods.
  • Sludge Treatment Wetlands (STW) have proven effective in converting sludge into agricultural biosolids, with this study focusing on optimizing the final rest period in the Mediterranean region.
  • Monitoring two WWTPs in Spain over 9 months revealed that a 6-month rest period after ceasing sludge feeding in summer is effective for producing high-quality biosolids with low contamination levels for agricultural reuse.

Optimization of sludge management can help reducing sludge handling costs in wastewater treatment plants. Sludge drying reed beds appear as a new and alternative technology which has low energy requirements, reduced operating and maintenance costs, and causes little environmental impact. The objective of this work was to evaluate the efficiency of three full-scale drying reed beds in terms of sludge dewatering, stabilization and hygienisation.
