Groundwater treatment plant for the removal of VOC, VC and BTEX

From the second desorption column, the water was passed through a gravel filter stage.
A downstream activated carbon filter served as a police filter.

The pollutants from the exhaust air of the stripping columns were oxidized to carbon dioxide, water, and hydrogen chloride in a compact catalytic oxidation plant.

The exhaust air was washed with the raw water to remove hydrogen chloride, resulting in hydrochloric acid, which was then used to stabilize the hardness for the stripping process.

Due to the installation of the plant in a residential area, special sound insulation was necessary around the desorption columns, the pumps, and the catalytic afterburning plant.

During an official sound measurement, it was possible to prove that the limit values of 40 dB (A) required by the Immission Act and the TA Luft were met.
