ITT Flygt has received its largest order to date in Austria worth over USD 1.6 million
ITT Flygt will be supplying the city of Vienna with fourteen 225 kW propeller pumps, the largest order received to date in Austria, at a total value of USD 1.6 million.
The pumps will be used as part of the redevelopment and expansion of the city’s wastewater treatment plant, which is having its capacity increased from serving the equivalent of 2.5 to 4 million people, to cover the increase of sewage connections within the city limits.
Vienna’s local water authority has taken the decision to redevelop and expand the city’s wastewater treatment plant, which was built in the beginning of the 1980’s. The redevelopment includes adding a dentrification stage to the cleaning, which will remove more than 70% of the nitrogen, and to increase the amount of BOD (Biochemical Oxygen Demand) removal from around 83% to 96%. The capacity of the wastewater treatment plant will also be increased from serving the equivalent of 2.5 to 4 million people, to cover the increase in sewage connections within the city limits.
In order to achieve this, 15 new racetrack aeration tanks each 11.400 m³, 15 clarification tanks each 13.300 m³ and an intermediate pump station powered by Flygt pumps, will be built. Eight of the fourteen 225 kW propeller pumps, each with a capacity of 2.7 m³/s, will be used to lift sewage from the old wastewater treatment plant to the new one, whilst the other six pumps, with capacities of 2.6 m³/s each, will handle return sludge.
The new section of the plant is due to start operation in 2005.
