Sludge dewatering using the reed bed system in the Gaza Strip, Palestine

Sludge treatment using reed beds is more attractive in the Gaza Strip than traditional sludge drying beds. Sludges having solids contents of 1–2% can be applied to reed beds at a loading of 40 cm/m2 every 2 weeks. The infiltration rate for a reed bed system is high, and the evapotranspiration rate is typically 170% of pan evaporation. The cost of sludge treatment using reed beds is 0.34 US$/m3 compared with 1.01 US$/m3 for treatment using conventional drying beds. This paper presents the results of using reed beds for sludge treatment in the Gaza Strip for 3 years.
