Ideas for a clean environment
In Bitterfeld, various industrial processes have caused very large quantities of chlorinated hydrocarbons to penetrate the aquifer.
The highly volatile pollutants are converted into gas using three-phase desorption. A catalytic oxidation process breaks them down into water, carbon dioxide and hydrochloric acid. The hydrochloric acid is used in the process.
The low volatile 1,1,2,2 tetrachloroethylene is also converted into a gas, but is then adsorbed using air activated carbon. The pH-value is re-neutralised using sodium hydroxide. Finally the water enters the water activated carbon stage, to ensure that the prescriptive limits are guaranteed.
