The aim of this study was to evaluate the dewatering and mineralisation efficiency of three sludge treatment wetlands (STW) configurations differing on plant species (Phragmites australis and Typha sp.) and filter medium (gravel and wood shavings). Sludge dewatering and mineralisation were monitored in three pilots STW for 2 years. The sludge volume was reduced by 80% in all configurations tested, the total solids (TS) increased to 16-24% TS and the volatile solids (VS) decreased to 50% VS/TS… CONTINUE READING
