Groundwater treatment plant for CFC contaminated groundwater
Ressources: Soil, Groundwater, Air
Flow rate: 15 (m3/h)
Processes: Desorption, Catalytic oxidation
In operation since: Oct 2013
KF Company: Harbauer Berlin GmbH
Very heavily polluted groundwaters with a phase component receive an additional pretreatment, which consists of a heavy material separator and a coalescence separator. The hydrogen halide compounds (hydrogen chloride and hydrogen fluoride) obtained in the catalytic oxidation are removed from the exhaust air in a separate washing column.
In order to reduce the energy requirement as far as possible, the purified exhaust air from the catalytic oxidation is used via a heat exchanger for preheating the process air.
The resulting acids (HCl, HF) are neutralized with sodium hydroxide solution. For the most part, the washing water is circulated to prevent unnecessary consumption of water.
The purified groundwater is discharged into the R-channel of Berliner Wasserbetriebe.
