Water system integration can minimize both the freshwater consumption and the wastewater discharge of a plant. In
industrial applications, it is the key to determine reasonably the contaminants and the limiting concentrations, which
will decide the freshwater consumption and wastewater discharge of the system. As a case study, the water system in an
oil refinery is integrated. According to the requirements of each water using process on the water used in it, the
contaminants and the limiting concentrations are determined. Then, the optimal water reuse scheme is studied based on
the water network with internal water mains. Next, multi objective optimization is considered. In the case that objective
function is minimization of the fresh water, water usage is reduced by 44% and when objective function changes to
simultaneous minimization of fresh water and total cost, water usage is reduced by 47%.
