Flue gas desulfurization wastewater

Flue gas desulfurization wastewater

Flue gas generated from thermal power plants commonly requires desulfurization and denitrification processes. In the wet desulfurization process unit, limewater or certain chemicals needs to be added in the wet scrubber spray tower to promote the reaction and absorption. The wastewater after wet desulfurization normally contains a considerable amount of heavy metal ions, COD and other components.

Challenge

High heavy metal content

High temperature

Acidic/caustic corrosion

Extremely susceptible to scaling

Solution

Jiarong Technology provides TUF tubular membrane hardness-removal system and DT/ST high-degree concentration membrane system to treat desulfurization wastewater. The systems employ a modular design for stable and consistent quality and rapid delivery.

Benefit

Zero-water discharge (ZDL) solution

Discharge recycle and reuse

High permeate water quality

Reduced chemical addition/consumption

Economical efficient

Compact modular design
