The treatment of wastewater from the flue gas scrubbing originating from waste incineration consists of neutralisation with limestone suspension, precipitation of the metals with lime milk and TMT15 as hydroxides, carbonates and trimercapto-S-triazine complexes, flocculation with iron (III) chloride supported by flocculants, sedimentation and multilayer filtration. The sludge is dewatered in batches using a chamber filter press. The pure water is partly used for cooling purposes.
