Project: Innovative removal of N, P and organic matter in effluents from recirculating aquaculture systems

Acronym CLEANAQ (Reference Number: call2015-81)
Duration 01/04/2017 - 30/09/2019
Project Topic CLEANAQ_x000D_ Recirculating aquaculture systems (RAS) provide technology for sustainable fish production in nutrient-sensitive areas such as Baltic Sea. Although RAS implies reduced discharge, most of the nitrogen (as nitrate) and some of the phosphorous and organic matter are, however, still found in the outlet of the production unit. Additional removal in terms of cost-efficient end-of-pipe treatment is therefore needed to reduce final discharge and comply with environmental conditions and regulations in the Baltic Sea._x000D_ Innovative solutions improving the efficiency and reducing the use of external resources are thus imparative for future development. Therefore, CLEANAQ seeks to develop novel technologies and procedures for brackish/saline aquaculture systems investigating and optimizing 1) Single-sludge denitrification using fish waste as carbon source 2) Carbon-free denitrification; using woodchip-supported denitrification and/or electrochemical removal 3) Removal of the phosphate load using organic flocculants._x000D_ To optimize the techniques, state-of-art stable isotope and molecular methods will be used for the analysis of microbial processes to support mass balance calculations in fish production using experimental and full-scale RAS. The technologies developed and applied through the project will support the design and application of resource-efficient technologies, ultimately allowing RAS to decouple fish production from environmental impact in the Baltic region.
