DEVICE FOR ELIMINATING CHLORINATED HYDROCARBONS AND AROMATIC ORGANIC COMPOUNDS FROM WATER

摘要

The device disclosed comprises a container (1) containing packing material (4) over which the contaminated water is distributed. In order to maintain a negative pressure in the container (1), and to extract by suction the resulting vapour/gas mixture, the device is fitted with a vacuum pump, as well as an outlet pipe (6) through which the purified water is drawn off. To improve the removal of the vapour/gas mixture, tubes (7, 8, 9) with perforated walls extend into the packing material (4) at several levels.
