Towards water operations of the future.
2018
Nowadays multiple use of “smart” word is provided in many fields including research. Sometimes it is a synonym for chic, elegant or straight. A smart water system is not the same as an elegant, glamorous or fashionable system. Instead it operates to fulfil the requirements of producing an acceptable product while keeping the energy and resource requirements at a minimum. However, while cost savings has up until recently been our primary aim of making water and wastewater operations more efficient, there is now a more pressing agenda of sustainability driving the smart agenda. The primary aim of developing our utilities into a higher level of smart is hence moving from a singular focus on co…
Cyber-Physical Systems for Smart Water Networks: A Review
2021
Author's accepted manuscript. 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 scienti…
Enhancing a Transition to a Circular Economy in the Water Sector: The EU Project WIDER UPTAKE
2021
A novel approach for resource recovery includes forward osmosis (FO) as a concentration step in municipal wastewater treatment. The current study investigates different pre-treatment strategies including biological treatment with a moving-bed bioreactor (MBBR) at different loading rates and particle removal by filtration and sedimentation. Membrane performance and recovery potential for energy and nutrients were investigated in laboratory-scale FO experiments in batch mode using pre-treated municipal wastewater as feed and 35 g/L NaCl as a draw solution. Initial water fluxes were in the range of 6.3 to 8.0 L/(m2·h). The baseline fluxes were modelled to account for flux decline due to concen…
