Aqualia and FCCCo complete the expansion of Glina WWTP (Bucharest, Romania)
- The facility plans to treat more than one million cubic meters per day in 2040, thus providing service to 2,400,000 people in the Romanian capital.
- The project has been executed by a consortium formed by Aqualia, FCC Construction, both in charge of the remodelling and expansion works of the existing plant, and by Suez, responsible for the construction of the sludge incinerator.
- The expansion and improvement works of the WWTP have posed a great technical challenge, since they have been carried out while the current facilities were carrying out their usual operation and maintenance activities.
- The works included, among others, the construction of a new pre-treatment line, the construction of a new biological treatment line with a capacity of 8.9 m³/s, the remodelling of an existing biological treatment line, the construction of 24 clarifiers secondary and the expansion of the existing sludge dewatering facilities.
Aqualia, in consortium with FCC Construction and Suez, has completed the remodelling and expansion project of the Wastewater Treatment Plant (WWTP) of Glina, a municipality near Bucharest, capital of Romania. The execution of the WWTP expansion and improvement works has posed a great technical challenge since it has been developed while the current facilities were in operation. The WWTP's work has included the construction of a new pre-treatment line with a capacity of 4.5 m³/s, the construction of a new biological treatment line with a capacity of 8.9 m³/s, the remodelling of a line of the existing biological treatment, the construction of 24 secondary clarifiers with a capacity of 4.5 m³/s and the expansion of the existing sludge dehydration facilities.
The construction of a sludge reuse plant from the WWTP has also been carried out with a treatment capacity of 173 tons of dry matter per day. This plant will significantly reduce the volume of total sludge produced at the WWTP through incineration technology and will carry out an energy recovery process, generating part of the electricity consumed in the process.
With this expansion, the new treatment capacity of the plant will reach 12 m³/s, which is equivalent to more than 1 million cubic meters per day, a capacity for which a time horizon of the year 2040 has been taken into account, when the plant will treat the water of up to 2,400,000 inhabitants, the population of Bucharest and the rest of Ilfov County. In this way, full compliance with all effluent quality parameters is ensured at the same time in accordance with current Romanian and European regulations.
The project has been executed by a consortium formed by Aqualia, FCC Construction, both in charge of the expansion of the plant, and Suez, responsible for the construction of the sludge incinerator.
The plant, in addition to treating all the wastewater, will co-generate energy thanks to the incineration of the sludge.
Aqualia has been working for more than 15 years in Romania, where it has previously developed the Agnita and Dumbraveni treatment plants, both in Sibu county, and Zimnicea in Teleorman county.
