Abstract
The invention relates to an apparatus for the purification of a liquid effluent containing pollutants, particularly metals and/or radionuclides, as well as to a process for purifying the effluent. An object of the invention is to provide a continuously functioning purifying apparatus. This object is achieved with the aid of an apparatus incorporating a confinement enclosure containing a support in which are immobilized living cells of photosynthetic microorganisms. The support is made from a material transparent to light rays. The apparatus also incorporates a mechanism for introducing and circulating the effluent to be treated and a culture medium within the enclosure.
