Abstract: Zero wastewater discharge has been the ultimate goal of green water utilization in process industries. To make the water network with zero wastewater discharge economically beneficial, the system should be optimized. Alumina industry is a heavy water consumption industry, hence studying water re-use and zero wastewater discharge (ZWD) for water system in alumina plants is very important. This paper analyzes a practical water system of an aluminum plant on the basis of graphical method for ZWD water system. The water system of aluminum plant features great amount of water loss and consists of several operation with fixed flowrate constraints. On the concentration-mass load diagram, the optimal water supply line considering water loss for the water system with ZWD is constructed. The optimal regeneration water flow rate and optimal regeneration concentration are targeted. Base on these targets and local recycling scheme, the optimal water using network with ZWD consi!
dering fixed flowrate constraints is obtained. The alumina plant accomplishes the goal of zero wastewater discharge and the freshwater saving rate achieves 62.7%.
