From sewage to irrigation water in Kenitra
Treating the combined wastewater of the Kenitra, Mehdya and Sidi Taibi municipalities
Kenitra, Morocco
Wastewater flow: 8.000m³/d
Biogaz production: 18.000 Nm³/d
Energy production; 800kWe/h
Protecting the river Sebou
As in the city of Fez, wastewater of the Kenitra agglomeration was being discharged after basic treatment in the Sebou river and eventually, 5 kilometers downstream, into the Atlantic Ocean. The new Kenitra municipal wastewater treatment plant turns wastewater into safe irrigation water. Half of the plant's energy needs is recovered from sludge digestion.
Recovering 40% of energy needs from sludge digestion
To limit operation costs, the embedded energy potential of the excess sludge is being unfolded in 2 anaerobic reactors. Under anaerobic conditions, the organic pollution is converted into methane. After desulphurisation, the clean biogas fuels co-generation units, producing the necessary heat to maintain the digestion process in the reactors, as well as electric power to recover part of the plant's energy needs.
With biogas valorization, grid dependency is further controlled. Up to 40% of the plant's power needs is recovered from sludge digestion.
