Kim Joao de Jesus Gregersen

Kim Joao de Jesus Gregersen is an Academic employee at the Section for Aquaculture, National Institute of Aquatic Resources (DTU Aqua), Technical University of Denmark. His research focuses on water treatment technologies in recirculating aquaculture systems (RAS), including biofiltration, foam fractionation, and mechanical filtration.

His primary research interests include Recirculating Aquaculture Systems (RAS), Water Treatment Technologies, Biofiltration, and Microbial Engineering. He investigates the efficiency of drum filters, swirl separators, and foam fractionators in maintaining water quality, alongside the impacts of disinfectants like peracetic acid and ozone on microbial communities and biofilter performance.

Recent publications demonstrate consistent innovation in RAS water quality management, emphasizing biofilter optimization through compressible media and integrated mechanical-biological treatment processes. His work addresses critical challenges in sustainable aquaculture, particularly particulate removal and nitrification stability under disinfection protocols.

Gregersen participates in major research initiatives including BioMeka (advanced water treatment technologies), ProBiOzon (protein skimming and ozonation), and UVOXIRAS (UV-based oxidation). He supervises PhD student W. Qi in water disinfection and biofilm activity research, contributing to DTU Aqua's mission of reducing aquaculture's environmental footprint.
