The aim of the project is to optimize operation of denitrifying woodchip bioreactors, which can be used for end-of-pipe treatment of aquaculture effluents to reduce discharges of nitrogen. Focus is primarily on reducing the environmental impact during bioreactor start-up by reducing the amounts of dissolved organic matter leaching from woodchips during the first month of operation, but also to investigate the bioreactors' ability to remove disinfectants (formalin and per acetic acid) to reduce the ultimate discharge of residual disinfectants from fish farms.
