AB  - Due to their design and mode of operation, French Vertical Flow Constructed 
      Wetlands (VFCWs) accumulate suspended solids from the inflow wastewater in the 
      form of a sludge layer at the surface of the first filter. In order to maintain 
      the treatment performance over the long term, the characteristics of the sludge 
      deposits and their evolution have to be well described. In this objective, a 
      panel of sludge deposit samples taken from 14 French VFCW sewage treatment plants 
      was investigated. Elemental composition and organic matter content, nature and 
      reactivity were analyzed. Results clearly revealed two categories of sludge 
      deposits, namely the "young-age plants" type (1 year of operation and less) and 
      the "mature plants" type (3 years of operation and more). Sludge deposits from 
      the "mature plants" exhibited same biological, physical and chemical properties. 
      Their organic matter was globally less abundant, more humified and less 
      biodegradable than in the young-age plants type. Their overall contents in trace 
      metals were also higher, although in a limited manner. The effect of additional 
      treatments, particularly FeCl(3) injection for phosphorus precipitation, was 
      observable in the "young-age plants" group. Finally, the sludge deposits sampled 
      from one particular plant with specific operating conditions were found to 
      exhibit very different characteristics from those of either groups identified. 
      This observation underlined the influence of local conditions on the typology of 
      the sludge deposits.
