“…Wang et al addressed that by introducing a single internal water main, freshwater consumption can be reduced sharply. However, freshwater consumption obtained by Wang et al 12 is much higher than the target value. Zheng et al 13 proposed a general methodology for the optimal design of the water-using networks with multiple internal water mains by using a superstructure and a mixed-integer nonlinear programming (MINLP) strategy.…”

“…Zheng et al 13 proposed a general methodology for the optimal design of the water-using networks with multiple internal water mains by using a superstructure and a mixed-integer nonlinear programming (MINLP) strategy. The most effective designs obtained by the method of Zheng et al 13 exceed the results of Wang et al 12 However, freshwater consumptions are still higher than the target values. Alva-Argáez et al 14 proposed a systematic methodology that empowers conceptual engineering and water-pinch with mathematical programming methods.…”

“…Let us use an example to show this by considering the limiting data in Table 1 of a water-using network taken from Wang et al 12 From Table 1, it can be seen that the limiting inlet concentrations of process 3, in ppm, (40,60,20), are lower than those of process 5, (110, 135, 60), and those of process 6, (200, 170, 150). However, it is difficult to tell if the limiting inlet concentrations of process 3 are lower than those of process 4, (30, 40, 70), because the limiting inlet concentrations of contaminants A and B in process 3 are higher than those in process 4, but the limiting inlet For a water-using network of single contaminant, it is clear that the lower the concentration of a demand stream, the lower the possibility for it to reuse the source streams.…”

A heuristic design procedure for water‐using networks with multiple contaminants

in Wiley InterScience (www.interscience.wiley.com).On the analogy of the water-using networks with single contaminant, we will introduce new methodology concepts: the concentration potentials of the demand streams and those of the source streams in the water-using systems with multiple contaminants, based on the overall allocation possibility of the source streams to the demand streams. In the design procedure, the performing order of the processes is determined by the inlet concentration potentials of the processes. The processes with the lowest inlet concentration potential will be performed first. When satisfying the inlet stream of the process being performed, the source with the largest quasi-allocation amount, which is defined in this article, will be used first. A few literature examples are investigated to show the method proposed. The results show that the method proposed in this work is very simple and the freshwater consumptions of the designs obtained are very close to the minimum freshwater targets.
