Peter (WP6) – Multilevel parallel GPU implementation of SQP solvers for nonlinear MPC
In recent literature, it has been shown that thenumber of steps in a sequential quadratic programming algorithm for a non-linear model predictive control (NMPC) problem can be greatly reduced by a parallel shooting method. Theefficiency of such a parallel shooting method further dependson how the algorithm is implemented on parallel computingplatforms such as Graphics Processing […]
Peter (WP6) – Real-time demand forecasting and multi-resolution model predictive control for water distribution networks
In this work, we develop a water demand prediction model for MPC that reliably handles unexpected changes from the daily pattern by incorporating a dynamical model over the current measured demand, fitted using machine learning methods. Secondly, in alignment with the new demand estimator, we also propose a multi-resolution MPC prediction horizon. This improves the […]
Alessio (WP6) – Uncertainty-aware energy storage investment planning through arbitrage in DA and RT markets using novel block orders
Energy Storage Systems (ESS) represent capital-intensive technologies set to play a pivotal role in the future energy landscape. In competitive markets, ESS rely heavily on cross-temporal energy arbitrage within day-ahead markets and across multiple segments, such as day-ahead to real-time markets. However, their revenue potential is heavily reliant on the accuracy of renewable energy generation […]
Alaaeldin (WP4) – Current direction regulates ion transport across layer-by-layer one-side-coated ion-exchange membranes in electrodialysis
Polyelectrolyte multilayer (PEM) modified membranes can attain selective ion separations in electrodialysis with several potential applications, such as sustainable brine management. To understand the ion transport across PEM-coated membranes, we coated six different commercial cation-exchange membranes (CEMs) with PEM via the layer-by-layer technique. Coating one side of the membrane with a PEM leads to an […]
Sophie (WP5) – European approaches to wastewater reuse regulation: A comparison between Spain, Malta and the Netherlands
Wastewater reuse is encouraged and facilitated by legislation and policy across the EU. A recent example is the EU Regulation 2020/741 on minimum requirements for water reuse. This and other regulatory developments have gone hand in hand with an increase in research in technological innovations that facilitate wastewater reuse, including advanced water treatment technologies. Despite […]
Tjerk (WP4) – Going from inner-skinned to outer-skinned polyelectrolyte multilayer based hollow fiber nanofiltration membranes
Recently, hollow fiber polyelectrolyte multilayer membranes (PEMMs) have shown great potential for removing organic micropollutants from wastewater streams. Currently, these PEMMs are made with the selective layer on the inside of the hollow fiber. However, to reduce the physical footprint of PEMM modules, it would be beneficial to have the selective layer on the outside. […]
Jan (WP3) – Risk characterisation of chemicals of emerging concern in real-life water reuse applications
Water reuse is a viable option to address temporal or structural water shortages. However, the ubiquitous presence of chemicals of emerging concern (CECs) in natural systems, especially the aquatic environment, represents a significant obstacle to water reuse and the receiving environment. Therefore, an extensive literature review was performed to identify current water reuse practices at […]
Alaaeldin (WP4) – Counter-ion mobility in cation-exchange membranes: Single electrolytes versus mixtures
Many electrochemical technologies utilize ion-exchange membranes for water treatment (e.g. electrodialysis), energy conversion applications (e.g. redox flow batteries), and electrochemical synthesis (e.g. bipolar membrane electrodialysis). Ion mobility inside the membrane plays a primary role in determining the energy efficiency and ion selectivity of the process. We investigated the mobility of Na+, K+, Mg2+, and Ca2+ inside […]
Alessia (WP3) – Presence of micropollutants and transformation products during subsurface irrigation with treated wastewater assessed by non-target screening analysis
While wastewater treatment plant (WWTP) effluent offers a potential alternative source for irrigation, the fate of organic micropollutants (OMPs), including transformation products (TPs), in effluent-irrigated fields remains largely unknown. Using non-target analysis (NTA), we investigated OMPs in WWTP effluent and their distribution throughout a full-scale subsurface irrigation (SSI) field where effluent was used for irrigation. […]
