La matière organique extractible et les lipides - Composition des effluents - Application au site de Morlaix

This report deals with the composition of lipidic organic matter in the raw and treated effluents from the urban treatment plant of Morlaix and its evolution during a daily cycle. The chemical characterization of the organic extract is given by its distribution in the lipidic classes and in individual compounds in the fatty acid and sterol fractions for some specific samples. The values of concentrations,fluxes and degree of removal in the plant for the soluble and particulate matter are discussed and compared with the corresponding data from the treatrnent plant of Toulon.
