The flue gas condensate from a power plant in Sweden is treated by water treatment technologies from EUROWATER. The produced flue gas condensate is waste water that is contaminated with heavy metals and organic pollutants. Several treatment steps are required in order to release the purified water to recipient.
The water treatment plant is designed for a maximum flow of 34 m³/h. It consists of two parallel sand filters for removal of suspended solids. Hereafter, two parallel activated carbon filters reduce dioxins and other organic pollutants. Heavy metals removal consists of two steps. First step is two parallel mercury (Hg) selective ion-exchangers. Second step include selective ion-exchangers for other heavy metals. Finally, a polishing filter with arsenic removal filling.
- Flow: 34 m³/h

- Chromium (Cr): < 0.5 µg/L
- Mercury (Hg): < 0.1 µg/L
- Nickel (Ni): < 0.5 µg/L
- Zinc: < 0.3 µg/L
