@article{(Open Science Index):https://publications.waset.org/pdf/14318, title = {Study on the Optimization of Completely Batch Water-using Network with Multiple Contaminants Considering Flow Change}, author = {Jian Du and Shui Hong Hong and Lu Meng and Qing Wei Meng}, country = {}, institution = {}, abstract = {This work addresses the problem of optimizing completely batch water-using network with multiple contaminants where the flow change caused by mass transfer is taken into consideration for the first time. A mathematical technique for optimizing water-using network is proposed based on source-tank-sink superstructure. The task is to obtain the freshwater usage, recycle assignments among water-using units, wastewater discharge and a steady water-using network configuration by following steps. Firstly, operating sequences of water-using units are determined by time constraints. Next, superstructure is simplified by eliminating the reuse and recycle from water-using units with maximum concentration of key contaminants. Then, the non-linear programming model is solved by GAMS (General Algebra Model System) for minimum freshwater usage, maximum water recycle and minimum wastewater discharge. Finally, numbers of operating periods are calculated to acquire the steady network configuration. A case study is solved to illustrate the applicability of the proposed approach.}, journal = {International Journal of Physical and Mathematical Sciences}, volume = {6}, number = {8}, year = {2012}, pages = {1018 - 1022}, ee = {https://publications.waset.org/pdf/14318}, url = {https://publications.waset.org/vol/68}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 68, 2012}, }
