Britt-Marie Wilen

Biträdande professor at Department of Civil and Environmental Engineering, Water Environment Technology

Britt-Marie is a Professor and Head of Division at the Division of Water Environment Technology at Chalmers. She specializes in wastewater treatment, focusing on biological and chemical processes in activated sludge and biofilm processes.Britt-Marie researches separation processes with a main focus on disc filtration and activated sludge floc formation. She performs this work in collaboration with Gryaab to create a clearer water which meets the new guidelines that have been introduced regarding phosphorous.Britt-Marie also researches nitrogen removal processes, particularly the use of anammox when removing nitrogen during wastewater treatment. She also works with aerobic granular sludge. This work is carried out in collaboration with professor Malte Hermansson at the Department of Cell and Molecular Biology at the University of Göteborg.
