  7. Abstract:
  8. This study deals with the treatment of medium density fiberboard (MDF) effluent aiming at the removal of TSS, COD, BOD and Turbidity by means of soil aquifer treatment (SAT). Removal of parameters were evaluated during transport of MDF effluent under unsaturated flow conditions in 1-m soil (sandy-clay soil) depth. The experimental results showed that the new process with SAT to be very effective. The TSS, COD, BOD and turbidity removal average was about 99%, 30%, 89 and 98.5% at the optimum operation condition, respectively. The SAT should be added before the UASB in order to achieve high removal rate of COD and BOD. The UASB (concentration sludge 40000 mg/l) after SAT treatment MDF effluent, COD and BOD were removed to approximately 80 mg/l and 20 mg/l, respectively. This system was reused after methane reactor in order to high removal COD and BOD. The TSS, COD, BOD and turbidity removal rate was about 99%, 53%, 76 and 99%, respectively. Finally in order to use this waste water in irrigation, the output wastewater from activated sludge, which was related to the last part of UASB system, was transported in 1-m soil depth. The results from this experiment were 83%, 31%, 89% and 87% for TSS, COD, BOD and turbidity, respectively. The results provided useful information for Industrial wastewater pretreatment whose water quality was similar to MDF effluent
