Process for removing ethers and polycyclic aromatic hydrocarbons from groundwater |
| abstract |
Disclosed is a process for purifying groundwater by initially separating off solid constituents, adsorbing ethers and polycyclic aromatic hydrocarbons to an absorber resin, desorbing the adsorbed compounds with steam and regenerating the adsorbed resin with an acid. The process enables ethers and polycyclic aromatic hydrocarbons to be separated off from polluted groundwater to such a substantial extent that the groundwater can be added to flowing surface waters without problem. The purified water can, if appropriate, be used as cooling water or, after further biological purification, can also be used as drinking water. |
