Resumo: Sludge management has become a key issue in urban wastewater treatment. Constructed wetland with common reed (Phragmites australis), for sewage sludge, dewatering (draining and evapotranspiration) and mineralization, has been used in Europe since 1988. This study aimed to characterize the sludge and plants (Phragmites australis) in constructed wetland for sewage sludge dewatering, operating since October 2001 in Barroca d`Alva. Three sludge samples in different locations, during June to September 2010 (June 16, July 25, August 19 and September 16) and analyzed for pH, electrical conductivity (EC), total and volatile solids (ST and SV), total Kjeldahl nitrogen (TKN), nitrate (NO3-) and ammonium (NH4+) nitrogen, total phosphorous, potassium, calcium, magnesium , iron, manganese, zinc and copper. Plants were analyzed in two dates (June 16 and September 16), for total Kjeldahl nitrogen and total carbon. The low organic matter content of the sludge, does not allow, its use as organic fertilizer. The sludge ammonium content was low in relation to nitric. Moreover, sludge presented low content of nitrogen, phosphorous, potassium, calcium and magnesium.
