Synthesis of batch water network for a brewery plant

Multilevel strategies for the retrofit of large‐scale industrial water system: A brewery case study

“…Both strategies use mixed-integer nonlinear programming (MINLP) model for water reuse and regeneration reuse in batch and semicontinuous processes (Tokos and Novak-Pintarič 37 ). The approach is illustrated with a brewery case study that integrates water consumers in two production sections.…”

“…The model was presented in Tokos and Pintarič. 37 In this work, an improved objective function was formulated in the MINLP model for water network synthesis, which prevents from multiple summations of not only the pipeline installed costs 37 but also of the storage tanks installed costs. This is required when the process is integrated with other processes over several time intervals.…”

“…As different storage capacities could be determined in different intervals, the largest value is considered as a final storage capacity of process k. Note that symbols used for sets, parameters, and variables are consistent with those used in our previous article. 37 The capacity of the storage tank of process k which is divided into operations n over several time intervals is determined by the expressions:…”

“…Applying the mathematical formulation for water reuse and regeneration reuse 37 with improved objective function as described above, to a large-scale integrated water network composed of several distant networks produces a huge mathematical model. Two two-level solution strategies are thus proposed to explore the reuse and regeneration reuse options between water consumers within the sections and among them.…”

Which is more cost-effective? A comparison of two wastewater treatment models in China–Singapore Suzhou Industrial Park, China

“…It is distinct from cost-benefit which assigns a monetary value to the measure of effect (Ceri, 2010) and is often used in the fields where it may be inappropriate to monetize the effect. Furthermore, it was ever used to evaluate the environmental performance of technology application (Tokos and Pintaric, 2009;Seppanen and Fisk, 2004;Chertow and Lombardi, 2005), compare the effects of different wastewater treatment technologies (Jardin et al, 2008;Telukdarie et al, 2006), assess environmental benefits of investment decision-making (Qi et al, 2006;Goulder et al, 1999), and examine the performance of environmental policy enforcement (Schoua et al, 2000).…”
