Sludge is one of the main critical environmental problems in the Gaza Strip. More than 400 m³/day of aerobic sludge and approximately 50,000 m³/year of anaerobic sludge are disposed of into the environment without any treatment. The random disposal of sludge pollutes the groundwater aquifer, contaminates the agricultural products and impacts the health of residents. Three new treatment plants will be constructed in the Gaza Strip to replace the existing ones. The activated sludge system is the proposed treatment technology instead of the existing stabilization ponds and aerated lagoon. It has been estimated that more than 3,700 m³ of raw sludge will be generating daily by the year 2025 in the Gaza Strip. Experiences of using reed bed· systems for sludge dewatering in many places in Europe and USA, together with monitoring results of a three-year pilot project in the Gaza Strip circumstances are promising. A reed bed system is easy to operate and maintain, and is financially attractive compared with conventional drying beds. A reed bed system can be used for a three-year cycle with an average hydraulic loading rate of 40 cm every two-weeks. [Continues.]
