“…Water network synthesis falls under the class of pooling problems, and total water network synthesis in particular presents the additional complexity of modeling the mixing pools of wastewater treatment operations to perform regeneration for reuse/recycle. For this purpose, more advanced tertiary treatment using membrane processes have been considered in addition to nonmembrane-based technologies. ,, In this regard, membrane regenerators such as ultrafiltration and reverse osmosis have found extensive industrial applications. , …”

“…20,66,78 In this regard, membrane regenerators such as ultrafiltration and reverse osmosis have found extensive industrial applications. [107][108] Although regeneration technologies are inherently nonlinear, to the best of our knowledge, there has been few work to date that consider a detailed nonlinear regeneration model for water network synthesis. Recent work in process synthesis have increasingly involved rigorous optimization-based models particularly for the separation section, [109][110][111][112] but a relatively small number of work has been conducted that incorporate detailed mechanistic or phenomenological models on the subsystems of a water network.…”

9 10Increasing water demand in the process and its allied industries coupled with global water stress 11 and scarcity has underlined the importance of water as a crucial resource and elevated a need for 12 widespread adoption of water reuse and recycle. This paper provides a state-of-the-art review of 13 the area of water network synthesis focusing on single-site continuous process problems since its 14 inception in the 1980s. The survey centers around model-based optimization or mathematical 15 programming methods for water network synthesis and covers key findings from the water pinch 16 analysis technique, which are often essential in enhancing model formulations. Major modeling 17 and computational challenges are discussed that explore the issues of nonconvexity, nonlinearity, 18 and uncertainty inherent in

“…PI technologies and methods could therefore be 172 adopted into the water and wastewater industries where they perform similar duties in other 173 industries. 174 Figure 2, below, summarises how PI technologies can: reduce energy consumption, 175 reduce foot-prints, potentially generate value from waste, allow for more flexible processing 176 to meet varying feed qualities, improve trace chemical removal, reduce the time to market, 177 reduce life-cycle costs, and a combinations of these objectives (Tayalia & Vijaysai, 2012). 178…”

9Process Intensification (PI) refers to the use of novel process technologies to achieve 10 significant (order of magnitude) size reduction in individual unit operations, or the complete 11 removal of process steps by performing multiple functions in fewer steps. This should lead to 12 significant reductions in capital and running costs, and improvements in process efficiency 13 and safety. There are numerous examples of PI being successfully implemented in the oil and 14 gas, pharmaceutical, food and drink, and fine chemical industries, but few in the water 15 industry. There are however a range of drivers for process intensification within the water 16 industry. These include ever more stringent environmental standards and more intractable 17 pollutants. The aim of this review was to identify PI technologies that could be used in the 18 future UK water industry, but require further technical development (to increase their TRL), 19 or transfer from other industries. Recommendations for technologies are given, as well as 20 routes to their implementation. 21 22 Highlights: 23 PI can significantly reduce the size of unit operations, remove process steps and make 24 processes more efficient and safer 25  The UK water industry is facing environmental, financial, and land constraints, all of 26 which may be drivers toward more efficient and innovative processing 27  There is significant potential for the application of novel PI technologies 28 2
