摘要：Membarane processes are widely used in both drinking water treatment and wastewater treatment. This method is separation process, in the most general sense, rather than treatment. In the meantime, it is not possible to avoid reject formation. For this reason, the biggest problem is the extra effort required to remove the reject from the membrane processes. In this case, the use of new membrane processes and new operation methods are needed. For this reason, at the first stage, textile wastewater were treated by classical electrodialysis (CED) process. 10% (1 L wastewater / 0.1 L rejected portion) of the concentrate stream was generated from this process. Utilizing the reject, 15 L of wastewater treatment was realized. At this point, the concentrate stream can be reduced to 0.67%. Likewise, in the bipolar membrane electrodialysis (BMED) process, when the initial solution of anolite and catholyte was placed as a 0.1L initial solution, the reject flow (20 L wastewater, 0.1 L anolite, 0.1 L catholyte) could be reduced to 1%. In this study, it was observed that the reject stream could be used repeatedly and minimized in the electrodialysis processes. At the same time, mixed acidic and alkaline solutions with pH value of 0,32 M H+ and 0,38 M OH- value were obtained by BMED process. According to the initial values, 47.5 times (0.38 / 0.008) and (0.32 / 0.009) 35.6 times more concentrated alkaine and acidic solutions were obtained.
