Specialties
Leiv was involved in the development of new control system design tools such as sensor models, sensor classification schemes, aeration system models, and process models. His work on fault modelling and fault detection strategies allows the design of more robust control systems. Intensive instrument testing and development resulted in improved sensors and the increased use of nutrient sensors in advanced control systems. He has full-scale experience from implementing aeration control strategies at wastewater treatment plants and developed a concept for a new generation of monitoring stations. Leiv authored more than 30 publications in the field of wastewater monitoring, modelling, and control.
