Detecting the end of nitrification in small and decentralized wastewater treatment systems using low-resource real-time control methods
Fox, S.; Clifford, Eoghan (American Society of Civil Engineers, 2018-06-12)There is increasing demand on operators of small-scale wastewater treatment plants (WWTPs) to improve biological nutrient removal and energy efficiency while being subject to unique challenges, including reduced resources. ... -
Development of a data driven FDD approach for building water networks: Water distribution system performance assessment rules
Mulligan, Sean; Hannon, Louise; Ryan, Paraic; Nair, Sudeep; Clifford, Eoghan (Elsevier, 2020-09-10)While fault detection and diagnosis is a popular tool in the process industry, its application in building water distribution systems is however still largely absent. In this study, a new set of Water Distribution System ... -
