The state-of-the-art wastewater treatment plant, located about two hours’ drive west of Cairo, can treat up to 7,5 million cubic meters of sewage sludge daily, making it the largest in the world in terms of size and treatment capacity. Thanks to the GEA decanters, the sludge dewatering plant is the largest in the region.  

The GEA biosolids Decanter prime is a customized solution for the treatment of municipal wastewater sludge. The prime line comprises seven machine sizes with a capacity of 15 to 300 m³/h. The centrifuge is therefore ideal for large capacities. Thanks to a unique machine design, the prime line has been energy-optimized to such an extent that the energy balance of the prime line shows savings of up to 50% compared to previous generations of machines. Among other things, this was made possible by the design of the decanter bowl in a deep pond design. The performance and design of the prime 8000 decanter are crucial given the special features of the West Delta wastewater treatment plant. The entire fan-shaped Egyptian Nile Delta only has a slight gradient of 20 meters to its mouth in the southeastern Mediterranean. In addition, large quantities of sewage sludge are produced. The entire Nile Delta begins around 16 kilometers north of Cairo at Qanatir el-Cheirat and covers a total area of 24,000 sq km. This makes it one of the world's largest river deltas.

GEA worked on the project with a consortium of four of the largest engineering companies in the Middle East: Metito, Orascom, Arab Contractors, and Hassan Alam.
