Wastewater Treatment for Waste Incineration & Power Plant

Hager + Elsässer have been awarded a contract to build a wastewater treatment plant for a waste incineration and power plant being built outside Copenhagen.

This plant will operate non-stop, treating wastewater to a high discharge specification, and is being designed and built to a particularly high standard to ensure long trouble-free and low maintenance operation. The treatment plant will handle the wastewater stream arising from the flue-gas desulphurisation system. Since such plants inevitably operate non-stop and so the reliability and up-time requirements for all parts of the whole plant are very demanding.

The plant is due to be built in 2012, and will include the following main plant features:
Primary Flow & Concentration Balancing Tank
Coarse neutralisation stage with FeCl3, Anti-scalant and CaCO3 dosing and sludge seeding
Fine Neutralisation stage with NaOH dosing
Precipitation stage with TMT-15 dosing
Flocculation stage with polyelectrolyte dosing
Lamella clarifier
Sludge thickener
Fully mechanised filter press for sludge dewatering
Post-precipitation stage with TMT-15 dosing
Sand Filtration
Arsenic removal stage
Final discharge monitoring
Extensive system flushing & cleaning facilities
Fume extraction system

Discharge quality requirement are:

This contract is the latest of many that H+E has built previously for similar applications. It affirms H+E's continuing, long-term commitment to the energy and environmental sectors.
