“…Feng and Seider (2001) have proposed a novel network structure with internal water mains to deal with the issue of reducing of water consumption and wastewater generation as well as to simplify the piping network in large plants. Kuo and Smith (1997) and by Wang and Smith (1994b) to set targets for the minimum flowrate in a distributed effluent system and to design such systems. Galan and Grossmann (1998) suggested an effective heuristic mathematical programming procedure for the optimal design of a distributed wastewater treatment network, where they optimize the superstructures given by Wang and Smith (1994b).…”

In this paper, we address the problem of optimal synthesis of an integrated water system, where water using processes and water treatment operations are combined into a single network such that the total cost of obtaining freshwater for use in the water using operations, and treating wastewater is minimized. A superstructure, which incorporates all feasible design alternatives for water treatment, reuse and recycle, is proposed. We formulate this structure as a non-convex Non-Linear Programming (NLP) problem, which is solved to global optimality. The problem takes the form of a non-convex Generalized Disjunctive Program (GDP) if there is a flexibility of choosing different treatment technologies for the removal of the various contaminants in the wastewater streams. A new deterministic spatial branch and contract algorithm is proposed for optimizing such systems, in which piecewise under-and over-estimators are used to approximate the non-convex terms in the original model to obtain a convex relaxation whose solution gives a lower bound on the global optimum. These lower bounds are made to converge to the solution within a branch and bound procedure. Several examples are presented to illustrate the optimization of these integrated networks using the proposed algorithm.

“…In the terminology of the pinch analysis, the proposed method sets the target prior to the detailed solution of the allocation networks. Once the target is set, an allocation network may be obtained using different methodologies proposed in the literature (Wang and Smith, 1994;Kuo and Smith, 1997;Feng and Seider, 2001;Prakash and Shenoy, 2005). It may be noted that the proposed algorithm is applicable for systems with a single quality.…”

Abstract:Various environmental regulations imply that it is important to minimize the cost associated with treatment of different industrial wastes prior to its discharge to the environment. In this paper an algebraic methodology, based on the principles of process integration, is proposed to target the minimum waste treatment flow rate to satisfy environmentally acceptable discharge limit. In the proposed methodology treatment units with fixed outlet concentrations are considered. It is observed that it is not necessary to maximize the usage of the treatment unit with the minimum specific cost. Hence, a prioritized cost for each treatment unit is devised to select appropriate treatment units that minimize the overall operating cost. Applicability of the proposed methodology is demonstrated through examples.
