0.2 Hours CPD
Description
Gerald Teahan, Process Scientist at Scottish Water, presents an overview of aerated facultative lagoons and explores how engineered aeration, natural biological processes and ecology work together to treat wastewater.
The session draws on monitoring and research carried out with the University of Strathclyde across three Scottish Water lagoons at Errol, Tobermory and Bowmore. It examines treatment performance against regulatory limits, the influence of Scottish climate and seasons, and the practical demands of keeping lagoons running wel
Key Topics Include:
-
Outlining how aerated facultative lagoons work, from the biogeochemical processes to the role of aeration, and why they suit smaller and rural wastewater treatment works
-
Exploring the monitoring results for BOD, suspended solids and pH, the Errol case study, and the effect of Scottish winters and summers on performance
-
Highlighting the operational challenges and lessons learned, including sludge accumulation, short-circuiting and aerator maintenance, and the safety requirements for working on lagoons
