  7. Abstract:
  8. The effect of the combination of MBR and MBBR systems to enhance the efficiency of water treatment plants has been studied. In this study, by embedding a UASB reactor in the presence of packing, as anoxic, two MBBR reactors as a single aerobic treatment and a MBR reactor once with and once without packing as the final purification tried to remove pollutants from artificial drainage and extend the life of the membrane system is designed to convey the wastewater treatment and irrigation is its quality standards functionality and the quality of its wastewater treatment standards for agricultural irrigation. Studied pollutants include COD, ammonia, nitrate, nitrite and phosphate. membrane fouling examined by measuring the EPS and SMP as the main causes of clogging of the membrane It was concluded that the addition of packing to the reactor to reduce congestion and increase time efficiency of the membrane to be. The removal efficiency of COD, ammonium and phosphate in the system respectively 92%, 93% and 80%, respectively. By comparing the performance of the system in terms of removing contaminants He may be the system in order to reuse the work, but by measuring coliform output of this system was observed that this system is the ability to remove sufficient to achieve the standard required, and a disinfection unit It is essential
