AB  - The design of French VFCWs leads to the formation of a sludge layer at the 
      surface of the first filters due to the retention of suspended solids from the 
      percolation of unsettled wastewater. This layer plays a major role in the system 
      but still little is known on its characteristics and evolutions. In this study, 
      suspended solids and sludge deposits sampled from two French VFCW plants were 
      analyzed by different methods in the objective to assess the evolution of 
      particulate organic matter (POM) along the treatment chain and within the sludge 
      layer, and identify relevant analytical indicators of these phenomena. The 
      treatment chain included an aerobic trickling filter followed by FeCl(3) 
      injection and two successive stages of filters. Thermal analyses showed that OM 
      contents of suspended solids decreased along the treatment chain. POM in inflow 
      suspended solids was predominantly composed of reactive, biodegradable compounds 
      which were partly hydrolyzed and mineralized notably at the trickling filter 
      stage. 3D fluorescence spectra collected from aqueous POM extracts confirmed the 
      evolution of organic matter from low-molecular reactive compounds to more complex 
      and stable structures such as humic-like substances. FTIR confirmed the 
      mineralization of POM's reactive constituents along the treatment chain by the 
      decrease in the intensities of the characteristics bands of aliphatic compounds 
      or proteins, and its humification in the sludge deposits through the relative 
      increase of the bands at 1634cm(-1) (v(C=O)) and 1238cm(-1) (delta(C=O) and/or 
      delta(OH)). Isotopic ratios delta(2)H/(1)H and delta(15)N/(14)N were found to be good 
      indicators of POM evolutions. The higher values of delta(2)H/(1)H and delta(15)N/(14)N 
      ratios measured in sludge deposits as compared to inflow suspended solids were 
      related to POM humification and to microbial processes of POM hydrolysis and 
      mineralization, respectively.
