THE CUSTOMER

With 90 000 people on the five continents, SUEZ is a world leader in smart and sustainable resource management. It provide water and waste management solutions that enable cities and industries optimize their resource management and strengthen their environmental and economic performances, in line with regulatory standards. To meet increasing demands to overcome resource quality and scarcity challenges, SUEZ is fully engaged in the resource revolution. With the full potential of digital technologies and innovative solutions, the Group recovers 17 million tons of waste a year, produces 3.9 million tons of secondary raw materials and 7 TWh of local renewable energy. It also secures water resources, delivering wastewater treatment services to 58 million people and reusing 882 million m3 of wastewater. SUEZ generated total revenues of 15.3 billion euros in 2016.

THE NEED

The city of Bucharest has selected a consortium composed of SUEZ, FCC - Aqualia to modernise the wastewater treatment plant (WWTP) and to build a treatment and sludge-to-energy plant in Glina, located south-east of the capital.

The wastewater treatment plant in Glina will be rehabilitated and extended by FCC - Aqualia, in order to ultimately provide wastewater treatment services for the equivalent of 2.4 million inhabitants. The sludge will be transported to the future treatment and sludge-to-energy plant built by SUEZ, with a treatment capacity of 173 tonnes of dry matter per day.

This plant will significantly reduce the total volume of sludge produced in the WWTP, using SUEZ’s incineration technology and Turboden Organic Ranking Cycle technology to generate electricity which will be recovered as part of the electricity consumed in the process.

This new project in favour the circular economy represents a further step forwards in the Group’s development in this high-potential region.

OUR SOLUTION

Two Turboden ORC will be employed in two treatment lines to recover the sludge in accordance with national and European standards.

Degremont® Thermylis® technologies, developed by SUEZ, will be used to significantly reduce the volume of the sludge produced by the WWTP by drying and then recovering energy with thermal oil heat exchangers and a production of electricity with ORC turbogenerators by Turboden, used in part to power the plant.
