  7. Abstract:
  8. Pharmaceutical waste has attracted considerable attention, in the Past two decades. These pollutants had not previously been detected in the environment. In fact, the concentration of pharmaceuticals became a matter of concern after the increase in the production and consumption of drugs. Nowadays, considering their higher consumption and more developed detection technologies, they are found in waste water, treated water, rivers, etc. The purpose of this research is to study treatment of a Synthetic waste water contaminated by Diclofenac and Ibuprofen in a Moving Bed Biofilm Reactor. An aerobic Moving Bed Biofilm Reactor (MBBR) with the volume of 8.5 liters and Kaldness packing filling ratio of 40% was devised. The controlled parameters were pH around the neutral range, temperature of 37 degree centigrade, Mixed liquor suspended solids of 2100 mg/l, and attached growth per packing. Tests were conducted for four different drug’s initial concentrations (2, 4, 7, and 10 ppm), two hydraulic retention times (5 and 10 hrs), two chemical oxygen demands (500 and 1000 mg/l). COD was determined using photometry method and drugs concentration was determined using HPLC (C18 column). Tests show, in general, Diclofenac is removed better than Ibuprofen in an MBBR. In HRT=10hr, Diclofenac removal is between 31 to 68%, while it is 15 to 39% for ibuprofen. In HRT=5 hr, Diclofenac removal is between 31 to 65%, while it is 0 to 30% for ibuprofen. It can be concluded that optimized retention times of Diclofenac and Ibuprofen are 5 hrs and 10 hrs, respectively. Another Furthermore, results indicate that Diclofenac is removed better in lower CODs, while Ibuprofen is removed better in higher CODs
