Cyber-Physical Systems for Smart Water Networks: A Review

There is a growing demand to equip Smart Water Networks (SWN) with advanced sensing and computation capabilities in order to detect anomalies and apply autonomous event-triggered control. Cyber-Physical Systems (CPSs) have emerged as an important research area capable of intelligently sensing the state of SWN and reacting autonomously in scenarios of unexpected crisis development. Through computational algorithms, CPSs can integrate physical components of SWN, such as sensors and actuators, and provide technological frameworks for data analytics, pertinent decision making, and control. The development of CPSs in SWN requires the collaboration of diverse scientific disciplines such as civil, hydraulics, electronics, environment, computer science, optimization, communication, and control theory. For efficient and successful deployment of CPS in SWN, there is a need for a common methodology in terms of design approaches that can involve various scientific disciplines. This paper reviews the state of the art, challenges, and opportunities for CPSs, that could be explored to design the intelligent sensing, communication, and control capabilities of CPS for SWN. In addition, we look at the challenges and solutions in developing a computational framework from the perspectives of machine learning, optimization, and control theory for SWN.acceptedVersio

Coupled, Data-Driven, and Real-Time Modeling and Control of Sewer Systems and Water Resource Recovery Facilities

Within the urban water cycle, the challenges posed in the operation of combined sewer systems include changing storms, evolving regulations, and impacts to environmental health. While building bigger infrastructure is one way to solve issues such as sewer overflows, budgetary constraints and increasing stresses to the system, such as climate change, limit the feasibility of this option for many communities and utilities. One alternative is posed by an increasing availability of sensors and data algorithms. Rather than building bigger, the use of real-time data and remote actuation provides a new avenue to autonomously adapt performance of the entire existing system. While promising, there are outstanding knowledge gaps that must be closed to bring the idea of smart wastewater systems to fruition. 1.) Sewer systems are highly dynamic and spatially heterogeneous. Thus a static, one-size-fits-all modeling approach will not accurately reflect the real-world system. This dissertation addresses this by presenting a data-driven toolchain that learns from historical sensor measurements to estimate current and future combined sewer conditions. By evaluating this toolchain on sensor data collected across the Detroit combined sewer network, it is discovered that wastewater and stormwater flow components exhibit distinct spatial and temporal variation, underscoring the importance of flexible re-calibration using the most relevant window of data. 2.) The efficacy and feasibility of real-time control across the sewershed poses a number of challenges. In particular, objectives for control across the scale of a city often force trade-offs between flood reduction and water quality; without informing control decisions based on these trade-offs, unintended consequences will affect performance across the system. To address this challenge, this dissertation introduces a real-time control algorithm to balance loads across distributed sewer assets and equalize combined sewer flow. The algorithm is evaluated in a simulated subsection of the Detroit combined sewer network. Trade-offs between flow and water quality objectives are evaluated to inform algorithm parameterization and considerations toward implementation. 3.) While the individual control of either sewer networks or water resource recovery facilities (WRRFs) has been explored separately, the opportunity to link these system components must consider the impact that sewer control has on WRRF operation and performance. By focusing on chemical phosphorus treatment, this dissertation quantifies the impact that WRRF influent dynamics and chemical addition has on treatment efficacy and efficiency. Namely, leveraging these two strategies together, phosphorus treatment is maintained or even improved, while chemical consumption is reduced. These findings exemplify benefits that can be accomplished by coupling the control and operation of system-wide assets.PHDEnvironmental EngineeringUniversity of Michigan, Horace H.

Book of abstracts of the 10th International Chemical and Biological Engineering Conference: CHEMPOR 2008

This book contains the extended abstracts presented at the 10th International Chemical and Biological Engineering Conference - CHEMPOR 2008, held in Braga, Portugal, over 3 days, from the 4th to the 6th of September, 2008. Previous editions took place in Lisboa (1975, 1889, 1998), Braga (1978), Póvoa de Varzim (1981), Coimbra (1985, 2005), Porto (1993), and Aveiro (2001). The conference was jointly organized by the University of Minho, “Ordem dos Engenheiros”, and the IBB - Institute for Biotechnology and Bioengineering with the usual support of the “Sociedade Portuguesa de Química” and, by the first time, of the “Sociedade Portuguesa de Biotecnologia”. Thirty years elapsed since CHEMPOR was held at the University of Minho, organized by T.R. Bott, D. Allen, A. Bridgwater, J.J.B. Romero, L.J.S. Soares and J.D.R.S. Pinheiro. We are fortunate to have Profs. Bott, Soares and Pinheiro in the Honor Committee of this 10th edition, under the high Patronage of his Excellency the President of the Portuguese Republic, Prof. Aníbal Cavaco Silva. The opening ceremony will confer Prof. Bott with a “Long Term Achievement” award acknowledging the important contribution Prof. Bott brought along more than 30 years to the development of the Chemical Engineering science, to the launch of CHEMPOR series and specially to the University of Minho. Prof. Bott’s inaugural lecture will address the importance of effective energy management in processing operations, particularly in the effectiveness of heat recovery and the associated reduction in greenhouse gas emission from combustion processes. The CHEMPOR series traditionally brings together both young and established researchers and end users to discuss recent developments in different areas of Chemical Engineering. The scope of this edition is broadening out by including the Biological Engineering research. One of the major core areas of the conference program is life quality, due to the importance that Chemical and Biological Engineering plays in this area. “Integration of Life Sciences & Engineering” and “Sustainable Process-Product Development through Green Chemistry” are two of the leading themes with papers addressing such important issues. This is complemented with additional leading themes including “Advancing the Chemical and Biological Engineering Fundamentals”, “Multi-Scale and/or Multi-Disciplinary Approach to Process-Product Innovation”, “Systematic Methods and Tools for Managing the Complexity”, and “Educating Chemical and Biological Engineers for Coming Challenges” which define the extended abstracts arrangements along this book.

Smart Urban Water Networks

This book presents the paper form of the Special Issue (SI) on Smart Urban Water Networks. The number and topics of the papers in the SI confirm the growing interest of operators and researchers for the new paradigm of smart networks, as part of the more general smart city. The SI showed that digital information and communication technology (ICT), with the implementation of smart meters and other digital devices, can significantly improve the modelling and the management of urban water networks, contributing to a radical transformation of the traditional paradigm of water utilities. The paper collection in this SI includes different crucial topics such as the reliability, resilience, and performance of water networks, innovative demand management, and the novel challenge of real-time control and operation, along with their implications for cyber-security. The SI collected fourteen papers that provide a wide perspective of solutions, trends, and challenges in the contest of smart urban water networks. Some solutions have already been implemented in pilot sites (i.e., for water network partitioning, cyber-security, and water demand disaggregation and forecasting), while further investigations are required for other methods, e.g., the data-driven approaches for real time control. In all cases, a new deal between academia, industry, and governments must be embraced to start the new era of smart urban water systems
