AB  - Olive oil mill wastewater (OMW) is generally recognized as an environmentally 
      troublesome by-product of the olive oil industry as its disposal without any 
      treatment is known to cause serious environmental problems. However, this 
      effluent has a high fertilizing power and constitutes, with urban wastewater, an 
      important low-cost source. Biological treatment of OMW, with a process combining 
      an aerobic reactor, 'Jet-Loop', and waste stabilization ponds, was investigated 
      for possible agricultural reuse. The focus of the present study was to evaluate 
      the contribution and the complementarity of the two systems in the total OMW 
      treatment. Bio-treatment was performed using a 100-litre Jet-Loop reactor working 
      volume achieving a chemical oxygen demand (COD) and phenolic compounds maximum 
      removal rate of 72% and 68%, respectively, at a hydraulic retention time of 10 
      days. Co-treatment of OMW and domestic wastewater in waste stabilization ponds, 
      with a hydraulic retention time of 22 days, reached a global removal rate of 66% 
      for COD while no trace of phenolic compounds was detected on this level during 
      the entire treatment period. Dynamics of faecal coliforms in stabilization ponds 
      showed a total removal rate of 99.9% (3 logarithmic units (Log.U)). Preliminary 
      results of agronomic tests on the ray-grass have evaluated the fertilizing effect 
      of the final effluent resulting from the co-treatment.
